Thx guys order as been perfect every time so far and keep up the great work 👍 👏

After a few UOA tests when I first got the truck @65k miles, I came the realization that I am going to change the oil based on fuel dilution not necessarily the oil condition. This came out to around 5k miles. The main difference that the 5w-30 OE Motor Oil did that others didn't was that it maintained 30w viscosity even with the fuel dilution. The increased cost of the oil vs others is marginal for the benefit of how well it works.

My best friend is a recently retired life long mechanic. He has always used Amsoil and referred me to it . I used it in my 2011 Ram 5.7 hemi, and it was amazing, better milage and performance. Recently upgraded to a 2016 Ram 5.7, about a week into the oil change the performance seems awesome. I feel confident in Amsoil and the oil lasts longer.

Good quality and good price on the website

Brought this car new in 2015 have always used Amsoil. Car has 257,000 miles and have never had any engine problems or oil useage. Put over 300,000 miles on our 1999 nissan altima before we sold the car. I would never use any other oil.

Best oil...had never used it b4, the quality is excellent, I get better mileage because it reduces all the friction, and it supports high temperatures better than others.

It was very good experience, fast delivery, no issues with the product, well packaged. I will definitely buy it again.

I started to use Àmsoil a few years back for all my cars and never had a problem. They all have over 200 k ànd run like new.

I like the comparison it had with a cold, poor drain, like the fact that it moves quicker when it's cold. I like they makeup of the product

AMSOIL rocks!!

I put the oil and filter on a 2017 GMC Sierra with 115,000 miles. It is a daily driver that my wife drives about 75 miles a week. I replaced the oil when the truck sensor said to change the oil and it worked out to about 7500 miles. Pleased.

I have been an Amsoil customer for many years, all I can say "satisfied" every time

I’ve used AMSOIL on this vehicle since it was purchased! Because of lifter problems due to gas saving cylinder cutouts problems have occurred usually starting off with clattering of lifters! I have not noticed any!!

i am happy with the oil but the promos like free hats or tools are not within range of the person buying for 1 car at a time dollar amount too high

This is good oil for older higher mileage vehicles and it’s mail so of course it’s great oil

As always Amsoil products are the best you can buy!

I just bought a Gmc canyon pickup with low mileage. It had a slight tic when idling so I used the Amsoil engine cleaner. The oil.came out black and drain fast like water. I put in the oem 5a30 and the tic was gone! Runs like new!

I have researched a lot of different oils. Amsoil stands out to be the best offed. I put Amsoil products in every application offered. 3 trucks tractor, lawnmower, small equipment. Giving my equipment the best chance of survival

Came packaged well even received stickers and gloves for oil change

I use these oils in all of my vehicles. Signature series for the newer vehicles and XL for the others. This lady decided to give it a try with the original..thumbs ip
