Customer Ratings & Reviews

Having never used synthetic oil before, I can only give my thoughts on what I perceive to be the quality of this oil and my perception is that this is the highest quality synthetic on the market. Pricey yes, but when you consider the suggested time period between filter/oil changes, it's a wash money-wise for a far superior product. I have a 2011 Tundra 5.7 that mfg and AMSOiL recommends 7.9 qts. I bought 9 qts just in case. After adding 8 qts it was still 1 qt low. Good thing I bought 9 qts because it took it all.

I use Amsoil products for everything on my ZL1, I would almost say it gives me a little more power an definitely the best protection hands down 💪🏼 Running Amsoil I’m not worried at all when I hammer down hard on it 🔥. By far the best money can buy if you want to be number 1 💪🏼 I now run Amsoil in all 3 of my vehicles 😅 Thanks for making a superior product

It does everything I want and more ! Nice to have such good protection that you don't have to worry if you go a bit over on changes !

Have been using Amsoil for 40+ years always my first choice.

Quality product.. use in 3 vehicles

Great oil, Jeep runs a little cooler than the original conventional oil came with.

Good oil good service. Would be nice if you just included funnels with each oil purchase. For what people pay for oil, it would be a great item to just give to customers. They are almost always necessary

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

Best oil there is. Keeps my 220,000 mile corolla sounding better than people's 5 year old cars.

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

Great oil have used it for years.

Great oil have used it for years.

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!
