Customer Ratings & Reviews

We run this product in the hardest and harshest conditions, run extensive oil analysis per all the cars we have and it’s liquid gold. Nothing comes close, nothing else replaces it.

I used Amsoil scene 1974 never lost a motor. Dragrace for many years too

I love it oil. Have been using this oil since 2011 on all my cars. One of my cars has 292k and another one has 262k. Never have any of the engines burned oil or have any type of leak. It is a true testament of the quality of this oil. Best of the best.

28 plus years running this oil. Feel confident its doing its job protecting from heat and wear,

A friend recommended AMSOIL, I’m a customer for life. Instantly noticed a difference in how smooth my truck ran. Highly recommended.

Missing 1 quart of oil from case I just got to open case to change oil before long trip and noticed I quart missing.

Awesome products!!

Very pleased with Amsoil products. Lots of science and technology that goes in to everything they sell. My engine runs very smooth and quiet. I have been slowly switching everything we own over to their lubricants

Never had problems with this oil!!!

I've used Lubrication engineers products for 40 yrs,but I always said if I cant get what I want from LE I'm changing to amsoil and that's what I did.It's great stuff.

The motor developed a head gasket and head failure at 125,270 miles. When the Ford mechanic removed the cylinder head the top of the head, i.e. cams, followers, springs, retainers, overall head surface were clean with absolutely no debris of any kind evident. Also the cylinder bores still had much of the cross-hatch pattern of the original cylinder honing remaining. The Amsoil Synthetic performs fantastically.

One of few products that I fully trust.

I have been using AMSOIL for many years now. I have 2 old cars 04 and an old Harley. Everything runs quieter and SMOOTHER AND GETS BETTER gas mileage. I will use it til I am gone thanks

Been dying for my warranty to get over to add Amsoil, but I couldn’t wait any longer. My car was begging for this stuff, had to be done. The car wants what the car wants!

good value, quick ship

First time using this. Immediate results as far as less noise and smoother running engine on my 2006 Yamaha Rhino 660.

Great product!. Nothing better for a supercharged Mustang GT. The #1 product out there.

I highly recommend Amsoil it is a superior grade of oil it seems to make it run better and quieter

Simply the BEST! Nothing but AMSOIL in my ZL1!
