Customer Ratings & Reviews

I started using this oil many years ago. When first bought it I used your oil filter and oil I put in my Ford 150 pickup truck 2002. I left in my truck for 6 weeks and drained the OIl and put in new filter and oil this cleaned the inside of my motor now the oil stays very clean. I now have over 363,000 miles on my truck still running strong

Best synthetic on the market. It's the only thing I use in my truck.

I always say that if Amsoil don't know how to make Synthetic Oil NO ONE does.. Because they have been the first since 1972..

Use for my car

Super impressed with all The Amsoil products. Extebdes oil change intervals makes it a no-brainer. vehicle Vehicle runs so much smoother, better gas mileage, it's a win-win

Great products

Amsoil protect my crankshaft when my oil pump failed and I get better gas milage, epa rating for my car is 35 mpg and I repeatedly hit 40 mpg.

2010 Toyota sequioa w/ 200k on the clock. Doubled oil change interval to 10k, doesn't use a drop between changes. Frequently idle and tow in hot Mississippi weather. Noticeably quieter valve operation over other top shelf synthetics. I just did a 200k service and noticed there is zero sludge in the engine. It was as sparkly as a transmission. I expect 300-400k out of this engine but it is a Toyota not a Ford!

I use Amsoil in everything machine I own. That Amounts to one diesel pickup to three gas pic up and two mustangs one being a 2011 Shelby GT500

300000 miles with once a year oil change. Amsol is the best

I say this product would out perform Mobil 1. Great to extended your drain intervals

The best oil I've ever used.! Hands down!

2013 Kia Rio o my has a 3.5 qt capacity. Best oil I've seen for this scenario

Used for engines and trans. I researched oil products IE: Royal Purple, Mobil 1, and Amsoil. Amsoil won.

Only Oil I will every use on my high performance cars

This is a great oil. I use this oil in two of my cars. I use Amsoil products in all my cars, truck, tractor, atv, and lawn equipment.

I use it in every engine i own. Cars, trucks, jet skis, power washers and lawn mowers.

I use this in a 2007 supercharged Mustang with good results and no problems.

My new Outback calls for 0-20 oil. This is a difficult thing to believe in considering I am old sckool and would rather have a heavier oil in the motor. So if I am going to put thin oil in this new car, then I want the best I can get. I been using AmsOil products for a while now and have no complaints .

My 302 race engine loves it! My old oil would barely last 1,500 miles but signature series is still golden after 5k! Thinging about swithing everything i have to it and see how a stock engine does up to 15,000!
