Customer Ratings & Reviews

Turbos make great sense for us living at high altitudes. The AMSOIL Signature oils have the right detergent package to avoid LSPI and the shear strength to keep engines lasting a long time.

Amsoil is the best, best by far of any motor oil

A never fail oil/filter purchase. I run this truck hard in both work and play, Amsoil keeps everything under control.

This is the best engine oil I have ever used for my Dodge Challenger. Thanks!

First time using the Signature Series 5W-30 and I like it so far 2014 Ford Taurus SHO

Excellent oil. I have used for years.

Amazing has my Dodge Challenger scat pack sounding great, and running smoother then when I got it. Definitely recommended!!!

16 year old Lexus engine sounds quiet and runs smoothly 👍🏼

Truck runs better than ever

Products are top notch and customer service excellent and shipping is fast and dependable.

I put this in my 2021 Toyota tundra 1794, as well as aired the Goodyear wrangler (stock size) tires up to 47# rear and 50# in the front, followed by unplugging the negative side of the battery overnight. After I hooked the negative back up, I drove several trips using the sport mode(as soon as I put it in gear I bumped it up to 6th gear and left it. This allowed the motor to not rev up when slowing down. After a week of driving this way I went back to d and not sport mode. Result= the truck went from a steady 12 mpg or lower up to a steady high 15 mpg up through so far 19.+ on state route easier driving. (Looking ahead to let off the pedal at times coasting made more since to stop) avoid cruise because it uses the engine to slow the truck down so it waste fuel mileage.

Use amsoil in everything I own. One car with 5W-30 has over 370,000 miles, going strong.

Great stuff, it's expensive but I'm gonna buy it anyway.... 🤣

Seems to keep the engine quite clean. No issues running 91 on a 2.7 T

Only oil I trust , to hold up to it's viscosity, wonder what's stronger, this, zrod or the dominator racing oil

Will use nothing else but the best!

It hasn't let me down yet. I recommend it to all of my family & friends.

When you use the very best oil it only makes sense to use the very best oil filter. My vehicles are only get the very best it’s worth paying a little more but the outcome saves money because less expensive breakdowns.

Have been using it for years In my Toyota vehicles. Have 442,000 on my 2008 tundra

I’ve used Amsoil for over 30 years. Will not use anything else.
