Customer Ratings & Reviews

Better gas mileage and extended oil change intervals. Would be nice if Amsoil would offer a 2500 mile oil filter to go with the 2500 mile oil.

I have used AmsOil products on 3 vehicles, i have used their oils, ow20 ss, motor oil, change intervals 10, 000 miles, also, my mechanic checks to see if it has stayed protective. i'll not use another product, because it is protecting my engine. Great Product and the folks at AmsOil backs it up!

Love this oil and actually feel the difference.

Received quickly and worked perfectly.

I use Amsoil in all of my vehicles and have no complaints. The oil seems to make my machines run cooler and smoother.

This works very well from a mileage and use for my car

I have been using AmsOil for about 10 years now and I have tried all the others. I am completely satisfied with all of their products. I use it in all my cars and toys.

I switched from other brands to amsoil and I haven’t looked back..

328000 miles and counting👍

Quality product

I have been using Amsoil in my cars and trucks since 1972. I have never been disappointed in any of their products. They have the best varieties and weight for any vehicle. If you want to change oil according to manufactures specs, or every 6 months or once a year Amsoil has what you need.

After watching ProjectFarm's videos on AMSOil and how it performs against its competitors, I was convinced this is THE synthetic oil to run in my truck

Put a friend's rav4 he says motor is quiet with less motor noises

First time using Signature Series. Very impressed. I noticed an immediate gain in MPG of 1 to 2 mpg. Would recommend.

The Best engine oil money can buy, in my opinion. Engine runs SMOOTH!!

BRING BACK THE GALLON CONTAINERS FOR THIS GRADE!!! Top notch oil that always gets glowing reviews from oil analysis done after every oil change at 10k-12k miles or 1 year in my 2017 Focus RS. Gallon containers have not been available for this oil grade for some time now, reason unknown?? The gallon containers are far more convenient for refilling the container for oil recycling and less waste of plastic.

The only oil I choose for my 2.0 liter eco boost motor. I have let the oil intervals go up to 11,000 miles using this stuff and still comes out brown never burnt. And oil needs to start developing a filter that can catch up to the oil lifetime! Great product nonetheless a customer for life!
