20 Best Oil For Cars With High Mileage (2023 Updated)

I have used Mobile 1 since 1978 and it has been the best oil I could buy. It saved my butt on Christmas morning as there was a huge snowstorm Xmas morning in 83′. Expressways were shut down due to high winds, drifting snow and temperatures at -30 F.

We spent Xmas eve at an emergency storm shelter. That morning, out of 50-80 cars, trucks & buses. My car and one other were the only ones that would start. Mobile 1 oil does not thicken in extreme cold weather like conventional oil.

My engines never had sludge build up like other cars and I typically keep my cars to 200K miles.

The opposite of convenient. I have been doing the same thing with the same product with every other auto parts store for many years. The longest it ever took to get the – it’s ready to be picked up has been 30 minutes, until Oreillys.

It not only took several hours for someone to walk 20 feet over a jug of oil, they sent the email minutes before they closed, so I had to wait for something every other place had. When I did pick up the oil, the guy was a jerk.

I will never be back. In a nutshell – you are employed by lazy people who give people like me many reasons to go anywhere but your place to shop. You should all do 2 things as far as I’m concerned. Be ashamed, and find a new line of work.

I’ve used Mobil 1 from Auto Zone since I bought my 2016 Mazda CX-5. It’s performing like the day I bought it. Mobil One can be bought anywhere, but, when you buy from Auto zone you get mare than the others.

I usually buy a 5 quart container and filter. The one time I couldn’t get the 5 quart container, AutoZone gave me 5 one quart containers for the same price. Additionally the filter that came with the deal was out so they upgraded me to a better filter.

I’m a veteran and they applied the 10% discount to an already good deal.

My comments is not on the product BUT the delivery. There was a leak in one of the plastic container. You can see the stain on the brown box before opening. They must know because they place plastic liner to contain the leak; also the invoice, oil stained, in the box has somebody’s name and different price.

Since there was still good amount oil left I choose not to return. Too messy. Took pictures of the stained box. Should have replaced the leaking container.

I’ve got a ’91 Nissan Pathfinder with 305,000 miles on it and this is what I use. She’s still running the same as ever, so this stuff seems okay to me! Also, this oil was recommended to me by a mechanic that I truly trust (I know everyone says this), but he had nothing to gain being retired and living 4 states away from me.

I also use it in my BMW with 235,000 miles.

The 0W-20 oil I use in both a naturally aspirated four cylinder and a turbocharged four cylinder engines. The manufacturer recommends the 0W-20 synthetic motor oil. At over 120,000 miles, the naturally aspirated four cylinder engine burns NO oil and remains at above the “add” mark for over 7,500 miles.

The turbo four has less than 50,000 miles and does not burn oil. the average MPG is above the manuracturer’s claim. cannot recommend highly enough,.

I’ve been using Mobil 1 0W-20 AFE oil in my 2016 Honda Accord, direct injected 2. 4L since 6200 miles. First oil change after engine break in, OE oil came out and Mobil 1 AFE 0W-20 went in. After 6000 miles of service using Mobil 1 AFE, the oil level dropped about a quarter of a quart as expected.

The OE oil evaporated over 6,000 miles as well and is normal for anyone concerned. I check the oil at every fill up at the gas station and keep the oil in the trunk. I live in a dry, very hot, dusty climate and a lot of stop & go traffic.

Under my current environmental conditions, it doesn’t make sense to purchase a higher end Mobil oil and risk leaving the oil in for a year or when the oil life monitor says to change the oil. 5 to 6 thousand miles or every 6 months between oil changes in Phoenix is cheap insurance.

I change it for peace of mind and ensure proper care of my engine. This oil has excellent flow at low temperatures and when you start your car after sitting overnight. Engine is very quiet and smooth when first started.

Quick flow is what prevents wear during starts and Mobil has it figured out with this oil. MRV viscosity @ -40 degrees Celcious for this oil is 9200, never seen a spec like that. Most other brands usually only list specs down to -35.

A lot starts happening that is important at these extreme low temperatures and there is a big difference in oil performance between -35 and -40 celcious. Hard to beat the specs of Mobil 1 AFE. Great product, readily available, competitively priced and just as good if not better in my opinion over OE oil.

Mobil 1 always seems to perform with high end products, highly recommend!.

we like this convenient packaging holding 5 qts for an oil change. Standard oil for regular older cars. No complaints good product. Name brand since it is Castrol!

I worked for Mobil and ExxonMobil in their Lubricants and Lubrication Sciences RD for 22 of my 41 years in this line of work. Mobil always had a no compromise attitude about MOBIL 1 engine oils. This one is their Premier Product in the MOBIL 1 engine oil line – you can be guaranteed it is great ! ! !I witnessed two BMW 318i vehicles run on Mobil 1 for over 1 million miles back during the 1990s and when the engines were torn down afterwards, the lubricated parts all appeared actually like brand new – still had the original machining marks ! ! ! Now that is great testament to a great engine oil ! ! !.

Bought my 2011 Nissan Frontier in 2014 with 48,000 miles. Used Ester oil until it became 15. 00 qt. Savey mechanic said use Mobil 1 full synthetic high mileage up to 20,000 miles. Glad I did, my truck now has 202,700 miles on it and actually runs better then the ester oil did.

When I took it in this last time the mechanic said he could not believe how clean my engine was for the amount of miles it had!!! Let me know my engine is still strong. Of course the dealership tried to get me to trade it in.

hahahaha NOPE.

I only use the top 4 brands now, Mobil 1, Pennzoil Platinum, Castrol Edge and Valvoline. Been very impressed with all of these full synthetic oils after using many different brands in 4 vehicles over the yearsI change my oil at 10k mile intervals.

OEM oil from the dealer and other name brand drained out so black light wouldnt pass thru it. The top oils I mentioned still have transparency at drain after 10k milesI even use this in my old 2000 truck with 206k miles.

I get better mpg when using the top brands like this.

This brand is top notch for your vehicle. It has a proprietary ingredient that elevated it’s performance above the others. It will properly lubricate your car, prevent the viscosity from changing to a disadvantageous thickness.

Cleans your engine. Works while you put your vehicle under stressful working conditions or if you are a daily driver. Helps engine to last much longer. It really works. If you haven’t been using it by now, start.

You will notice a difference. The price you pay for this is worth it down the road when you don’t get a CEL costing your hundreds, if not thousands. Helped my old 03 pilot get to 316650 miles with OEM tranny and engine, that’s a rare sight with that year.

No problems when I sold it. I told them to keep it going, use Mobile 1.

My girlfriend at the time had a Hyundai Sonata and was long overdue for an oil change. This oil along with the ExxonMobil brand gasoline is the only motor oil/ gas that goes into the motor. As a result I’ve noticed slight gains in the maintenance time-frames; I’ve also seen a dramatic difference in how the motor idles and performs under high pressure and excessive use.

As a Dasher this is the only oil I trust to keep me in the race!.

IšverstiShow in original languageSwitched at 170K to Pennzoil 5W-30 High Mileage. 1) Up until 168K I had been using Pennzoil or Castrol synthetics. 2) I just changed at Toyota: – plugs – coils – plenum gasket – valve cover gaskets – front VVT solenoid – coolant NOTE: Pictures of front valve-train show differential heating/drain-back of oil.

Right-hand side to left (towards timing gear) the color is “med-amber” to “brown,” no sludge, but some “crusting”; above average in cleanliness, BUT what appears to be a design error in even oil flow.

First highway trip after work by Toyota dealer engine used 3qt of Castrol 5W-30syn in 700mi. Stuck ring?! (Note: most it ever burned was 0. 5-1. 2qt synthetic in 3,000-3,500mi; have owned the little truck since 48K) Post atypical oil consumption: 3) Put in Castrol 10W-60 syn.

NO oil loss on road trip of 900mi. ZERO loss. 4) Followed with 4:1 Pennzoil 5W-30 High Mileage + Marvelous Mystery Oil. (rolled around town for 1 week to clean out engine –first time) 6) Changed oil to correct weight & filter (Penn 5W-30 High Mileage + Toyota factory filter as usual) 7) Second road-trip to same destination, 900mi.

ZERO oil consumption. NOTE: Toyota mechanic and I know the engine design and sludge problems associated with this engine class. My oil change interval since purchasing has always been 2,500-3,500mi. plus I change the coolant per the recommended time/mileage.

Main engine seals replaced at 90K with timing belt. (Did not replace valve guide seals. ) MY MECHANIC (former NASCAR Master Tech, now with Toyoda’r, recommended switching to conventional high-mileage oil to see it is would solve the recent consumption.

Switching to Pennzoil appears to have done just that –no consumption. CAUTION: I have been told that once you switch to high-mileage oils to never switch to non-high-mileage oils. Apparently the oil seals once they “swell” need the additives to maintain that state.

Heck. Pennzoil High Mileage seems to work and it is totally inexpensive! The Toyota oil filters are good for 7,500mi. I think I will just drop the oil every 2,000-2,500 at the local outdoor place before changing the filter at the 5K mark.

I am off the extreme long life of keeping my precious Red Line ester-based OR Pennzoil Ultimate synthetic oil in the pan for some extend period (which for me was 4K/oil change). —I am just going to do the OCD guy-thing and change my oil every 2,000 with this Pennzoil.

Why not?!! -David in NC 3/2016.

IšverstiShow in original languageIt all began when procrastinating for exams or not quite wanting to settle down a do my taxes. It was a situation of “Let me do something useful before getting back to the real work.

” Bob’s the Oil Guy was introduced to me by tech friends and it has always had some degree of informative factual knowledge. However, what it really was missing was a definitive, comparative TOP 10 list for gas/diesel/marine/aviation.

(That’s really all we need. Certainly it is interesting to now know that products like Red Line use fully synthetic base stocks, and that some filters have X-micron filtration, but for 95% of situations we just want the go-to products which will give us better/best lubrication and long-term peace of mind.

Pennzoil: after an adolescent tour of competing oil brands, I have settled on a simple rule of thumb for all of our family cars: (1) use factory filters (2) change the oil every 2,500-3,500mi, because most people will not actually do it until 4,00-5,000mi (3) use conventional oils (4) if you are actually changing at a 2,500-3,500 interval, then don’t bother changing the filter each time -use it twice (most factory filters for gas engines are rated for 5,000-7,500mi) (5) Main point – quality conventional oil, frequently changed, beats any fancy ideas of $15-20/qt synthetics.

IšverstiShow in original languageI have been using pennzoil high mileage oil in almost all of my vehicle’s since 2006 and i will continue to due so. Back in 2006 i bought my first car a 1992 mitsubishi eclipse 1.

8. When i started it up for the first it poured smoke from the exhaust pipe, but for 500 bucks i didnt expect much. My father told me to go down to the auto parts store an get the supplies to due a full tune up.

Standing in the autoparts store looking confuse at the massive selection of oils i asked one of the clerks which oil would be best for my vehicle, he told me ” anything but quaker, how many miles are on your car? ” i told him 147xxx.

He then asked if that was my car that had the mushroom cloud follow me in and i reluctantly said yes. He then told me to grab a big gold bottle of pennzoil. The funny part is that after about 1000 miles i noticed the smoke started to go away.

After 3000 miles it would only smoke lightly at idle and 2 oil changes later you would swear the motor had been completely overhauled. I have never been more impressed with a product. I have 3 vehicles now and all of them use some type of Pennzoil product.

My 94 Acura Integra GSR i purchased from the original owner 3 years ago. Since i have owned it has never had anything other than Pennzoil high mileage and it runs like silk.

I have been using this oil since my first vehicle 20+ years ago. The price is good, quality is better and the life and viscosity hold up as good if not better than any other oil on the market. I run 5 quarts of high mileage oil and 1 quart of Lucas high mileage heavy duty oil stabilizer.

Living in Michigan you have major temperature swings from really cold in winter to really hot in the summer. It holds up great, not to mention all but a couple vehicles I’ve owned have rolled 300,000+ miles.

I own a1997 Camaro with a 3. 8 engine and been using Quaker State high mileage 10w30 for the longest time. Upon my last oil change I noticed that the oil itself didn’t look the same as a synthetic Blend should look.

I’m a mechanic and see a lot of different oils and this last formulation from QS was NOT UP TO PAR! Certainly I will let them know about this. My engine was even noisier due to now junk I put in. Anyway now to good news, did my research on Valvoline HM oil, bought it, just changed oil after 3 days on what I thought was good oil and what a tremendous difference!!! My engine never ran this smooth ever! Listen do it yourselfers.

This oil is way more than I expected. Try it and be impressed just even within the first 10 miles. Big difference. Thanks Valvoline for making this oil. Fantastic product and keep up the great work you do as an synthetic HM oil makers!!!.

I like this synthetic oil because my vehicle have a lot of mileage and is very dureable. The price of the product is important for me , autozone have a very prices and offers than help me a lot for me , with my economic situation, some times the workers in autozone help me when I have a duda, because I don’t know almost nothing about the cars.

Thank you autozone.

IšverstiShow in original languageFirst Id like to mention Project Farm on YouTube, who does small in home tests using coffee pots, freezers, and a spinning lube test. These tests prove instant results for the small amounts of stress theyre put through.

The tests dont prove the longevity and cleaning aspects of engine oilsMy review:I went on this quest on YouTube and forums online to find the best synthetic 5W30 for my Tacoma. I checked out Home Deliveries USA Basics and Shell Rotella as well as this Mobil 1 and Supertech.

All are great oils, I found that the Shell oil had slightly miniscule more harmful metals than Mobil 1 but less than Home Deliveries USA oil. I also learned these companies will take out or add different things to have the SN plus badge which may take away from the longevity of the lubricating or cleaning qualities.

Home Deliveries USA doesnt have a write up for their oil like most other companies including Wal-Mart which is supposed to be the same Warren oil. For that simple fact I took it out of my choices. Home Deliveries USA and Wal-Mart are known to find the cheaper oils to resell and may end up changing in the future from Warren.

Mobil 1 is a trusted name and has all the requirements of a synthetic oil anyone should need. I have not experienced burning or loss of oil in either of my vehicles, one of which has 270,000 miles on it.

I dont run my oil 10 or 20,000 miles or whatever people are doing lately. I change my oil between 3 and 5000 miles which I know for certain is good and healthy maintenance to keep my engine running clean and strong.

I recommend that for everyone regardless of what these companies are claiming. I trust myself and my maintenance schedule. None of these companies are going to replace my engine if what they are claiming is false.

Mobil 1 is the oil Toyota uses from the factory and this along with my small research is enough for me.

IšverstiShow in original language1998 Tacoma, I used to drive this truck for 250miles/day, Using Castrol-GTX/3000miles. Soon as it reached 1500miles, gpm went from 20 to 17. I tried every things that people recommended on the internet to improve gpm.

sparkplug changed every 25k-30kmiles(do not use Bosh Platinum, just OEM Nippon Denso plug). Nothing worked. Soon as I switched over to Mobil1 Sync with OEM oil filter. My truck drove better, smoother, quieter and gpm remain @20gpm until the next oil changed which is 10Kmiles.

You can see the Viscosity of the oil remain the same, just darker. So I switched all my whole family vehicles(5 Toyotas, sedan-truck-van-SUV) to used this type of oil since 2000. Since I maintenance all vehicles myself, this 10kmiles oil change save me a lots of times and $$$$.

Let me tell you an impressive story about this oil. I gave my son the truck for his college years, in 4year. When the truck did not run(because of the MAF sensor clogged), he called me to come checked the truck, there was no oil on the dipstick.

DRIED!!!! Soon as I cleaned the MAF, I cranked the engine, it started right away. there is no issue with the engine. I still driving it now. over 200kmiles/24yrs still running like new. why buy new vehicles since mine run and looks like new plus paid off.

This oil brought my dog back to life. It was amazing how he’s been dead as hell for 8 years then a crusty dog skeleton just climbs out of the ground like that. Highly recommend if you’ve ever killed something or someone I’m not judging.

Brings em right back.

This stuff seems to work like it has synthetic properties even though it’s “premium conventional” oil; in fact it seems to make my 383,000 mile (yes you read that right) 99 Nissan Maxima’s engine run smoother than the full synethetic I tried at my last oil change, and I still don’t have to change it at any less than about 8,000 miles.

One more thing–there are a LOT of people on the review thread for this product mistaking this for Mobil 1 full synthetic oil which it is NOT–it’s not even a blend–it’s a “premium full conventional” oil, but it works as well as full synethetic at least in my opinion for a MUCH cheaper price.

I own a Cub Cadet GT3200 tractor with a 25 HP Kohler engine. I have used Mobil 1 since breaking in the tractor. Today my dealer replaced a blown head casket and I have un retouched photos of the inside on this engine.

Amazing as to the cleanliness. I would like to send them to you so you could use them in a commercial.

with this only being conventional High Mileage Oil It still gets twice the amount of miles between changes of the standard 10w/30 Mobil motor oil. Toyota Tercels with normal motor oil you have to change them between after 2500 to 3200 driving miles.

upgrading to the high mileage over 75k on motor has also extended between oil changes to between and after 5500 to 6800 miles as I look at the condition of the oil on the rags when checking the oil on my 1997 Toyota Tercel ce starts getting dark at 5500 and darker at 6500 change you oil as you see fit between 5500 to 7000 k using this oil.

I have three Lexus automobiles and I wouldn’t use nothing else but mobile one. I always felt that’s spending a little bit more is well worth it. I will never change. Mobil 1 forever

Have used these oils in my cars for decades. One Honda has 240k and it is still going strong

I like AutoZone, but I went to buy full synthetic and preferably high mileage full synthetic oil. The shop had no 5w20 synthetic, and of course it was the sale product etc. I asked at the display near check out about more, and got pointed to the back.

I floundered around in the back of the store, found this product as a weak substitiute, asked again at checkout and got mostly shrugs. Nobody seemed to know why 5w20 was so scarce nor had any idea on where to get it.

I’ll try a more friendly helpful store next time.

I have been using Valvoline every sense I was a young man. It has never failed me. I drove one of my vehicles to 178,000 miles , had a manifold leveling. After taking off the manifold the mechanic ask me what type oil I used, I told him valvoline.

He said it was one of the cleanest motors inside that he has worked on. I use ,Valvoline in everything I have, cars, trucks, motorcycles, and 4 wheelers. I will never use anything else.

I’ve used this for my 2005 Chevy Tahoe when it had 150k mile and now I just picked it up for my 2013 Dodge Charger v6 with a little over 100k miles. I wouldn’t do full synthetic unless you got 180-200k miles so anything under that, I recommend “Synthetic Blend!” And valvoline is my only choice when it comes to oil! I also combine it with an STP high mileage filter too!.

Mobil oil has been a leader in the industry for decades and one of the first to pioneer full synthetic oils which have longer life and keep the engine running very well. My 3. 0L Ford is VERY happy to have such quality oil and purrs like a tiger with it.

This oil seems to keep internal engine clean unlike paraffin and clay based oils from competitors which gum and clog up inside the engine. Having torn down and repaired or rebuilt over 100 engines myself, I can spot a quality oil from a cheap oil instantly.

I’ve been changing my own oil for 34-years. That’s the ONLY way to ensure my precious engine isn’t subjected to the vicissitudes of 1/ incompetence 2/ sabotage in the oil-change industry, sadly. My research showed that Mobil 1 is the BEST most-affordable synthetic.

I only use Mobil 1. I only use 5W-30. So when I saw BJ’s great price, I was grateful. THANK YOU BJ’s! P. S. DIY your own oil changes. Oil change is NUMBER ONE preventive maintenance for your engine’s longevity.

Keep good records. Change your own oil.

I did call autozone. About. This. Issue. I bought this. Mobil oil 5w30. 5 Q. It was. Used oil. The 5 Quart. Was open the oil was used oil I call for investigation from autozone. No body call me back.

Autozone store has a. Camera. Can you. Guy’s investigate this issue.

IšverstiShow in original languageI have used MOBIL 1 SYNTHETIC in all my Porsches (street and track) since the 80’s, but that is another story. This story is about a lawn mower which I bought new and ran “wide open” as a residential “bush hog” for 32 years.

I changed the oil every spring with MOBIL 1 SYNTHETIC and noticed each year the oil while dirty (because of the atrocious operating environment) the engine used no oil and performed flawlessly. I became fascinated at about 20 years when I realized this lawnmower was falling apart in every way, wheels, carb, housing sheet metal, studs and bolts backing out of the engine, it was a complete wreck EXCEPT: it burned no oil and suffered no mechanical failures after running for decades and thousands of hours wide open (wished I had a HOBBS).

To say the least, I loved this mower, my friends and neighbors howled at my eccentricity, but I paid them no mind, I know and understand true devotion, PLUS I had an ongoing SCIENCE PROJECT which I was going to push (literally and figuratively) to its conclusion.

At 30 years the mower deck was “fully ventilated” and was probably dangerous, it needed its third set of wheels and the whole affair was just simply “string and bailing wire”. None the less, I was not giving up on “The Red Devil”.

I had owned this mower half my life and I was beginning to wonder who was going to be the last one running. I had hoped to open the engine one day and examine the wear index. However, at 32 years my better half insisted that “The Red Devil” had to go.

I presented it to a young ARMY vet (who had admired it from afar) with the understanding that he would only use MOBIL-1 SYN and contact me IF the engine ever needed to be taken down as I wished to see the mysteries within.

In great solemnity he assured me he would honor the terms and nervously loaded The Red Devil it into his truck. I take great comfort in knowing that if there is a heaven for lawn mower engines, “The red devil” is holding court! I concluded years ago that The Red Devil’s longevity was 100% due to MOBIL-1 SYNTHETIC.

To this day, I can not hear a mower run without harking back to all the good times with The Red Devil. In spite of all my pleas, my attorneys say I do not have a case against MOBIL and have suggested therapy.

IšverstiShow in original languageI always use Mobile 1 10,000 mile oil. I use it on the lawn equipment, wood chipper,and snowblower too. For my car its lasts about 8,000 before I change it. When I change it it is very dirty so maybe I shod do it sooner but I wait for 8000.

On the pickup, milage is low so I leave the oil for 1 year all the time. Done this on 4 cars over the past 20 years wirh no problems.

IšverstiShow in original languagePrice difference. I don’t mind paying a little extra, but when I saw what I could have paid i was a disappointment ,I was shopping at Sam’s club and just happened to find the exact oil Mobil one full synthetic at 6.

99 a quart. And realized i paid 9. 99 a Quart. At Oriellys. I was very surprised.

I’ve used mobile 1 since I can remember. My Z just turned 202k. Been running mobil 1 in it since I purchased it with 25k on it. I’m very tentative about how I change oil as well, I drain, refill with new, run it for a few minutes to clean out what’s still in the cooler, block & lines etc, because I just don’t believe in dropping the plug and draining what’s in the pan.

Then after it’s run with the new oil I drain it and use compressed air thru the oil filter Orpheus to completely rid every drop of oil remaining in the system. People poke fun and say I’m crazy, but they then wonder why my vehicles last ridiculously amounts of mileage never requiring repairs.

I’ve done this with all my vehicles and it’s proof that it works, and Mobile 1 products are what they say they are. Ive disassembled engines after running mobile 1 products and am always amazed how clean they appear internally.

Laugh all u want about my method, but my odometer always tells the tale and dispells the haters. Mobil 1 products are the ONLY products I will ever use in my vehicles, hands down no question.

I wanted to change the oil on my 92 F150 before it went to its biennial smog check. My truck has well over 150000 miles, and the oil was pushing over 3000 miles of use and several years of inactivity.

My man Scotty Kilmer, on YouTube, recommends changing the engine oil as an item that will help a vehicle pass inspection. I purchased not only this quart but also a five-quart jug of GTX High Milage 10w-30.

The 351 takes just under 6 quarts. In my neglectful maintenance, the oil I drained out was very dirty, but now, a week later with new oil and filter, it is running fresh and clean. So yesterday I passed my smog check at Honest Smog, and I am all set to pay the DMV.

I am puzzled why Castrol GTX Motor Oil is in my list to review for beauty products. I am going to review it though because I have used this product. I have to make this clear. this IS NOT a beauty product.

It is a motor oil that I used in my car and I can highly recommend it as a motor oil for a vehicle. My brother is a mechanic and recommended Castrol GTX and I used it for the life of my car and my car never had any oil issues.

I changed my oil every 3,000 miles and I never had a problem. I highly recommend if you are looking for a motor oil, but ask a professional before using first.

What can I say about synthetic motor oil? Aside from the color of the container and the pretty label, it didn’t look any different than other synthetic oils on the shelf. Since my vehicle is “mobile”, I purchased the “Mobil” oil.

Wasn’t too concerned about the mispelling because the pronunciation was the same whether the “e” was there or not. The price did make me question why I have a vehicle that requires synthetic motor oil.

Holy boogers it is pricey. Nonetheless, I’m almost certain the cost is worth it, or I’m just as stupid as everyone else buying “the best” synthetic motor oil. Well, I bought 2 quarts, a big oil conglomerate made $20, it’s in my engine, and my engine didn’t complain.

Surely, it would have spit it back in my face had the flavor been off or it was expired and stinky like warm sour cream. The truth is that I was so excited to put this oil in my engine that I forgot to put the oil cap back on.

200 miles later, I went to check the oil and low and behold the cap was sitting right there on the fan shroud. Silly me, I’m an idiot. But gosh darnit, my engine is full of oil, it’s running the same as it did before, and I’m sure this oil had nothing to do with it except raise the oil line on the dipstick.
