Customer Ratings & Reviews

Been using amsoil products for years and I’m a firm believer that it prolongs the life of your engine. Had gas trucks with north of 400k miles on them by using these products. Hands down the best oil out there

This is the first time that I have used Amsoil. Defiantly will use again.

It works excellent, it takes along time for the oil to get dirty when I noticed other motor oil gets dirty in the first few thousand KM.

Very user friendly online ordering. Arrived on promised date. Continue the good works.

Excellent product and protection to my GMC PU. Will not use any other product in my vehicles.

My 2013 Mustang GT loves it !

Works great in my 2015 jeep Cherokee!!

Again, this is the best oil you can buy. It will help prevent and stop leaks, improve mileage and overall improve ride

Blackstone Labs did oil test after 12,000 miles and oil was still serviceable

Over 200,000 on the truck I use this oil in and it will probably go 200 more great products.

It’s a good product and great service.

I use amsoil in my 2014 Ram with a 5.7 hemi, this engine is known to have oiling problems that cause it to fail. I have 113000 miles on it and no lifter or cam failure yet.

I use the 5W-20 XL to do oil changes for my daughter's 2009 Kia Sedona. She bought is used a few years back and after she had the dealer do her first oil change and I noticed they were using a bulk 5W-30 I told her to let me take care of it. I have done one initial Amsoil Flush and am using the specified 5W-20 since. I use Signature Series in my cars, but I to give my daughter a break on price the XL series is a good option. I inspect the filter pleats and the detergency of this oil continues to clean this engine as I find carbon debris, but less with each oil change. Been using Amsoil since 2005!

I own a 2004 Mazda RX8 and this was my first time running a synthetic oil. After the oil change, car ran extremely smooth. The car idle smooth, vibrated less, an accelerated seamlessly through the RPMs. Great product worth the money.

Excellent performance. Smoth cold start. Love it

I have used Amsoil for 30+ years; diesel tractor/various cars, trucks, motorcycles, and boats. My 6th, current truck is a 2013 Ram, 90k miles; my 10th, current car is 2010 Lincoln MKX AWD 110K miles. My 13th and current motorcycle is a 2006 Victory 8 Ball, 38+k miles, and one trip cross county in summer of 2008. I have never had an oil related engine problem.

Love this product a lot I use it in my truck every oil change recommend highly
