Customer Ratings & Reviews

Will take a 3000 mile trip in may. So far no issues.

Seems to make my 2002 Tacoma run smoother. Pricey but would recommend if had discount codes.

It’s becoming expensive but I believe it is still the best out there. If you can afford it buy it. No regrets.

I've used this for several years now, and it continues to live up to it's description!!

This is the best oil I have ever used my engine oil temperature is running about 8 degrees lower engine is also running smoother and quite I will continue to use Amsoil highly recommend

Product as advertised, shipped as expected, received in tact & without issues.........you get what your willing to pay for !! : )

Not an engineer, yet I believe this to the the best oil I can buy for my higher rpm street car.

So many years I’ve used other oil brands until I found amsoil I’m glad I’ve found the best oil for my vehicle amsoil has the best products I love it

I use and change this oil, once every year, in all of my small engine equipment. When changing the oil, I always mix 80% of this oil along with 20% of Duralube Engine oil. I believe that this oil is far superior to any non-synthetic or synthetic oil that is currently available on the market today.

I use and change this oil every 15,000 miles in my truck. When changing the oil in my truck I use 4 quarts of this oil and add 1 quart of Duralube. This combination/mixture seems to keep my engine running smooth. My truck currently has 150,000 miles on it and it doesn't burn or use any oil.

Engine work perfect

Have used nothing but Signature Series 0W20 in my 2019 Toyota Tundra 4x4 Platinum since first oil change (self change) and AMSOIL oil filters! These products are unequaled in the industry for performance, longevity as well as other AMSOIL products I use, MP HD Metal protector, glass cleaner and silicon spray etc. Will use AMSOIL EXCLUSIVELY if results and expectations are continually met with superior products!

Amsoil synthetic 10w 30 is the best oil I ever had. The engine runs smoother.

Great oil, I have been using Amsoil for almost 40 years.

This is my first time using a Amsoil product and since using this oil the engine seems not as noisy on cold starts. Time will tell me if this oil was worth the price

I would recommend amsoil for all vehicles I use it in all my vehicles.Tractors and snowmobiles also have amsoil in them.

The only oil I would use in my cars

I am very happy with the product!! Outstanding product I did the routine oil change 2 weeks ago and the motor oil still very clean in my opinion this product meet the criteria necessary to be the best motor oil in the market without any competition.

Using Amsoil products for my vehicle is as good as it gets in my opinion. For me it's a piece of mind knowing that you're using the best there is for protection.
