Customer Ratings & Reviews

Fast shipping. Great product! Amsoil is the best!

Amsoil all in one service is very efficient, and quality of oils are top.

This is the only oil I'll use in my Tundra, keeps her running strong.

Great product

Run this in my 99 expedition 6.3L 250k+ and stillet not a problem with the motor. Change every 7500-10,000 and oil is still clean on the dip stick

It is a great oil did not burn I mean very little engin is very quit no matel grinding noice.

I have used XL 5W30 since this car was new. At 240,000 kilometers it uses NO oil between changes, gets great fuel economy and looking in through the oil fill cap it is clean as new inside. The GM oil monitoring system still says I am at 30% at 18,000k.

Used this in my 05 Sequoia for the past 20K miles. Never have to worry about my engine getting what it needs in any terrain.

Smooth running, saw gains of 0.5 mpg.

Great Oil wish it was a little cheaper

I use Amsoil in all my vehicles. Oil retains viscosity better then I even hoped. I do change at the recommended manufacture interval, but it is noticeable especially in my Turbo vehicle toward the end of the interval the manufacture oil would start to break down and Amsoil has maintained consistency.

Good value, great quality

First time using haven't changed oil yet. I use and oil in all my vehicles.

I like the fact that I change my oil twice a year with good protection and is priced as much or less than conventional oil

I have used this brand on and off for 13+ years in my 4Runner, alternating between it and the Signature Line. I finally settled on the XL and I prefer to change my oil twice a year and this model works well with my schedule and mileage.

Been using Amsoil on my motorcycle, car, truck and lawn tractor for years. Best oil out there IMO

Put Amsoil in all vehicles. Getting great gas mileage and runs smooth ... ?????????

I use Amsoil in everything I own. Even my lawn care equipment and generators. I've never had a oiling problem since I started using it in 1986.

its great products

I use this for both the Chevrolet Crate engine in my Chevelle and my Camaro SS LS3. Best protection money can buy. Wouldn't think of changing.
