Customer Ratings & Reviews

Just switched over from 0w30 to 0w40 big difference. Smoother, no rev idle on cold start doesn’t drop suddenly.

I'm changing this oil every 10,000 and oil analysis showes it still has a long way to go! Stuff is great just as I expected. No oil consumption and no burn after 10,000. Buy it you won't regret it.

I changed the oil on my newly acquired Porsche Boxster. I chose this product because it meets the Porsche A40 specification. It was not cheap because this car carries 8 qts. I use Amsoil in all of my vehicles. The Porsche likes the oil as it seems to rev easier.

I changed the oil in my Mercedes Benz which has 490550 km's on it. Since 1998. From motul oil to Amsoil. I noticed an increase in overall performance, smoother starts, and the combination of the gas additives, with your oil did the trick.. thanks to Jay at Below Zero synthetics in Alberta.

I have used this exclusively in two MB with the 3.5 liter V6. One has 205k miles with no issues. I add (not recommending this, just my system) some Amsoil 5W-50 to raise the viscosity and HTHS to 4.0 or above...

When you want the best you buy the best AMSOIL

I’ve ran this AMSOIL since I got my hemi engine broke in on my dodge ram truck and it’s always seemed to perform well. I beat on my truck a lot haha so I wanted a above average oil that I knew could help with the abuse my engine takes

I have used nothing but Motul since owning the vehicle but I didn't realize that BMW had switched to a new specification, BMW LL-01FE. Since I had used Amsoil in other vehicles with great success I decided I would switch this vehicle over to the right specification as well as switch to Amsoil engine oil along with their engine oil flush. The engine sounded differently almost immediately and after a few hundred miles runs completely different. The vehicle runs completely different and is much more responsive and powerful. Well worth the money.

I ordered the incorrect oil at first, but the exchange process was easy and professional. Shipping was outstanding and that makes for a happy customer who gladly order again, thank you AMSOIL.

I have tried 3 different kinds of oil to eliminate or reduce oil loss in 2.0L Turbo charged gas burner in my 2018 VW Passat. I had in the shop multiple times because it burns a quart of oil every 4000 miles so I constantly had to carry an extra quart of oil in the trunk. The service department manager said “It is normal” for that to happen…Why hasn’t it happened with any other new vehicle in my entire adult life? I checked the oil at 2000 miles and zero oil loss and the oil looks like brand new!

I've been using this oil in my Mercedes Sprinter 6 cylinder turbo diesel for 80,000 miles. I've been using 15,000 mile change intervals. It can still go between changes without ever needing to add a quart.

Good quality oil engine runs more smoothly in my 4 cyl turbo i would highly recommend this product

After 36,000 miles of dealer-performed maintenance services and oil changes, I switched to AMSOIL for my 2021 BMW G01 XE with the B46 engine. I now replace the oil every 8,000 miles and, based on lab test results, at 74.000 miles _now, my engine remains in pristine condition internally. I plan to keep this car for over 10 years, aiming for 250,000 miles while maintaining its 'like new' performance. My previous experience with AMSOIL was with my 2004 BMW X3. Using AMSOIL's European Car oil, I clocked 280,000 miles, and the engine continued to run strong. This new oil is the best on the market. Thank you, AMSOIL!

Purchased this vehicle with about 80,000 miles on it using another synthetic brand oil. I switched to Amsoil at the first service interval and have not suffered any ill effects. I still use the Mercedes change interval determined by the ECM which is usually about 10,000 miles. No measurable consumption between service intervals and the vehicle now has 150,000 miles.

It is the outstanding best in quality

RETIRED 43 YEARS AUTO TECH AND USED ALOT OF AMSOIL ESPECIALLY UROPEAN,ALSO I USE IT IN MY MOTORCYCLE AND FOUR WHEELER.GREAT PRODUCT.

This oil was exactly what I needed for my 1.4L MultiAir engine. I just used it to perform an oil change after purchasing my car from its previous owner. I could tell an audible difference on the new, smoother startup. The gallon jug saved me the fuss of having to fiddle with a bunch of pesky seals and was easy to pour in a sideways orientation. Will gladly be purchasing as an oil change bundle in the future.

I only use amsoil, nothing else

It is the best of 5w40 engine oil for my audi b5s4. Quality is better than the other brands. At list for now. Hope it will stay and won’t change

I love the product and company both the best on both sides of the Mississippi. I'll help you sell more in Laguna beach. Land of Mercedes Benz etc
