Customer Ratings & Reviews

My wifes subaru used to burn the oil to the point of being black within less than a 1000 miles after an oil change. Tried Amsoil, at the time of the oil change it came out looking slightly darker than than fresh oil....incredible! Her car also used to use 2 quarts between oil changes, now only uses 1. When I put it in my F150 the engine was noticeably quiter! I'm definitely sold on Amsoil!

I finally talked my Friend into trying an oil Change to Amsoil. After changing he told me that his truck seemed to be running better, starting much easier, and he thought he was getting better milage. A few days later he told me that now he knew he was getting better milage, about 2mpg. His truck is an older Chevrolet half to 4wd extra cab. I personally was converted a few years ago but thats another story. We can call my friend Brent, He has been building hot rods and high performance motors for years. He wanted one grade higher in weight than was recommended for his truck because of the high miles but now thinks he would have been fine. He is converted and wants to get gear oil and atf so he can change all his fluids to Amsoil products. We will both be changing differentials and transfer case lubricants at the same time.

I have been aware of Amsoil since the late seventies. It is a superior product and the only synthetic I use.

The 5.7 sees some harsh use during the summer. Towing, extended idling time and dusty roads tend to abuse oil. The Amsoil stands up to the job. Because it is still under warranty I do not exceed the manufacturer recommended service intervals but lab tests show the oil can go well beyond that.

I love this oil and use it in my 3 cars and truck,with the 25,000 mile oil filters.I use this oil in my tractor also.I feel that AMSOIL is the best around and I've been very happy with it.

I use for my family cars, and my boat

Always the best choice for my Nissan Van. Runs so smooth, even with all the miles.

BETTER FOR MY SUV

ExcWeds my needs. Works great only thing I would chage is look at kits for cars like you do for motorcycles and a lower price would be nice.

Awesome Product Nothing but Amsoil

Many years ago I had an 87 ford f150 with lifter noise at 100k miles. I ran across an Amsoil dist. at that time, I changed to Amsoil, noise went away and I put another 150k miles on the truck and the engine was still quiet when I sold it. All I ever did to it was a new timing chain. Been using Amsoil ever since in every vehicle.

Great oil and great price.

It runs great in my car, even after 10,000 miles it seems to stay clean. Helps my cars engine idle and run smoother, just a super good product.

Use in my HD Suburban It actually made the truck run cooler and quieter!!

I use this in my 2013 GMC Sierra 1500 Z-71. It's been a great product. Living in cold temps, and usually making short trips, this fits the profile my truck needs.

use it in our Honda, very pleased

For years, I used mobil1. When the time came, I switched to Mobil 1 high mileage. About 2 years ago I started to get a subtle knock coming from the bottom end of the motor. It also started to use oil between oil changes. When I switched to Amsoil, not only did the knock go away immediately, my now 170,000 mile engine consumes no oil between oil changes.

The best oil money can buy

I've been using this for some time and never had any issues what so ever.

use it in my truck so far so good
