My 2014 Chevy Impala Limited loves AmsOil signature series. My engine is running considerably quieter than when using Valvoline. Waiting to see what it looks like when I'm getting closer to an oil change to see how much oil gets used vs Valvoline. If you care about your vehicle and want it to last a long time, make the switch to AmsOil Signature Series!

Great motor oil! Have been using it for years in a 2013 Acura TL.

Great product will always and forever use it

Switched over to AMSOIL a few months ago and I'm very happy with the change. Would recommend to anyone, worth every penny.

This is an exceptional product, perhaps the very best. However the price is quite high. If I were not such an AMSOIL fan I would probably consider something less expensive.

Great wear with this oil

This is the grade that Whipple recommends and is perfect for my Mustang. Have performed several top speed contests, hitting 181MPH in the 2022 Spring Fling Arkansas Mile. Oil looks great and very little in the catch can.

First oil change in my 22 Silverado and I am always g2 run amsoil in it. Wish they had the right filter for me though

Best stuff out there. My Type R loves it! Only oil I will ever use!

Solid quality product best I can tell. Asides from the engine oil that came from the factory, this is the only product that has ever been in my wife’s 2015 Ford Escape. No problems at all!

AMSOIL 100% synthetic motor oil is one of the best engine oils on the market for any vehicle. Just like how clean blood is vital to the success of how our body operates, the types of motor oil you choose can also affect the success of your motor. After 6K on my AMSOIL 100% synthetic oil, I had an oil analyst test done on the oil. It passed with flying colors! The lab indicated, for my style of driving, it was suggested I could drive 10K-12K between oil changes with the current oil I'm using. I would never go that long between oil changes; however, I usually change my oil every 7K or every 6 months. It's reassuring to say the least to change my motor oil knowing that it is still capable of protecting my motor many miles beyond.

Best oil I’ve ever bought!

I can tell my engine likes this oil, runs very smooth and my gas mileage increased.

I have used signature series oils for many years in multiple different vehicles. Several of my vehicles have high miles logged every year but we also use in a couple pickups that do not see ideal operating conditions. We have not experienced any oil related failures.

I run thin in my 6.4 hemi and have no issues 100000 km's and going

Best oil made!! I have used AMSoil my whole life. I’ve always kept my vehicles 10+ years no problem with this oil.

Best oil ever I use on all my cars I have two honda accord and a civic . I drive my car 115 miles a day to and from work car has 220000 and still feels like new.

factory oil for my car is Ford's synthetic 5w50 but I have always run Amsoil in this vehicle and it has never let me down. Everything seems better than running stock oil on my car and with it being a performance turbo car it definitely makes a difference.

Simply the best oil out there for my 150k Toyota Tundra. Runs like new.

Vehicles are to expensive to go cheap on the most important thing you put into it.
