Customer Ratings & Reviews

Amsoil is a must for all engines. Especially GMs direct injected ones with DOD and AFM technology. Save yourself the headaches of failed lifters and high trans temps and swap out of of the other fluids and replace with Amsoil signature Series. Well worth the worries and investment.

Good product, fast shipping

Been using this oil in my Subaru for years and it’s always been great!

This is my first time using Amsoil for my life on my new 2024 Subaru Forester Wilderness (Odometer: 1500 miles). I quickly realized this oil is much smoother than the stock oil while revving up and also quieter during idle. After 3000 miles of usage, I will send this used engine oil sample to Blackstone lab for analysis and finish this review.

Gale Banks talked about this while I was doing jeep stuff and I am thankful that AMSOIL is here in the US and I can get it on this website. Now back to jeep stuff

Just bought a new Jeep and used my first three free oil changes at the Stealership, now I can use this for the rest of its vehicle life!

Will buy nothing other than Amsoil for my vehicles and motorcycles.

AMSOIL always has everything thing I need and fast delivery

Works great

I have the notorious Hemi cold start tick. I’ve used other full synthetic oils such as mobile 1, Pennzoil, and eventually the Walmart oil. AMSOIL eliminated the cold start tick!

Performed as advertised!

Good selection of oil packages with quality filter, and less expensive with home delivery than purchasing at local auto parts store. Will do this again next oil change.

Would not but anything else in my vehicle

With this oil and filter combination you really get you moneys worth.

I use Amsoil and everything my motorcycle my lawn mower and my pickup

I run AMSOIL in all my engines. I am always impressed with the improvement in engine noise and longevity of the oil quality.

I have converted another person over to Amsoil. Ive' used it for years without any issues.

On time and exactly what I needed.

I have been using Amsoil motor oil in my 1993 k1500 5.7 for over 15 years. My truck has over 250,000 miles and it as never had any internal engine worked done. Still running strong.
