Customer Ratings & Reviews

Less valve tapping on cold start ups and seems to run a couple of degrees cooler. Love this stuff. I use it in everything I own.

These products work as they should never need to question

My next door neighbor got me started using Amsoil some years ago. I now use nothing but Amsoil in all my vehicles. It is an excellent product and it is really cheaper to use than conventional motor oils because of the extended change times. I have run Amsoil as long as 24,000 between changes with no problems. I now change my oil when the vehicle computer tells me it is time to change and that is usually aroung 9,500 to 10,000 miles.

The best thing I found out about using this product...cost savings... with my membership and having only to change the oil 2 times a year ( on 3 cars ) as a Preferred Customer and the ability to go 12,000 miles between oil and filter changing I save $$$ dollars compared to buying synthetic oil from local auto stores..I usually go every 6 months between the oil change because of the change of weather in my area and I very really put 12,000 miles a year on any of my cars so it does keep that worry off my back when I know the oil has enough life on it if I run a bit late changing it .

Been using this product for several years now. My vehicles run like new, quiet and cool. Talked my boys (2) into using it as well an d we use the products on 3 motorcycles. All vehicles run great. I change filter on the cars every 6k and the oil, yearly, regardless of miles. Works just fine. use Wix filters for everything.

I have used Amsoil products since y2k without fail and recommend it to everyone I know. Motorcycles, yard power equipment and my latest suv adventure story... have you ever ran out of oil or burned your engine out of oil, I have with regular oils and those vehicals were dead afterwards. Short here is no oil high temp oil came on nightmarish lost 6 quarts of Amsoil... 3 months later and with replaced Amsoil as if it never happened

Currently have 433,000 miles with the same engine. I only use Amsoil in my car!

Best oil on the market

Before i used amsoil my engine had a loud and very noticeable tick. After switching to Amsoil synthetic the tick went away and the SUV sounds like a new car. When stopped you can barely hear the large 5.9L V8 idling away, it so quiet.

If I go past my oil change I don't have any concerns because the oil still looks new and protects my engine.

This is a great product and works well in any vehicle.

I use it in my f150 and I love it

I used it in my motorcycle and it quieted the engine right down and it ran smoother than ever.

changed from 10/30, works like a champ in my 2005 Silverado 225,000 miles pressure stays constant even under load

In all types of trucks, cars, boats and motorcycles

My truck mileage increased as soon as I switched from Mobil 1, truck has 260000 miles on it

Put this in my light duty, full size pickup. Noticeable difference right away. Engine quieter and clean.

I've been using Amsoil products for over 30 years. I had stopped for a period of time. I've been using this product now in my 2015 Focus since I got it. 30,000 miles and the inside parts of the engine I can see through the fill port are as bright and shiny as the day I bought it.

I have been using Amsoil for years. Everything from Signature Series to XL. All of my vehicles out-last anyone else's I know. I gave my daughter a 1997 Toyota Corolla years back and just put it to sleep with 387,000 miles on the clock. I have a 2005 Acura RL with 168,000 miles and it too runs like a top! I attribute the use of Amsoils synthetics to its longevity and have no doubt there's another 168, 000 left in her. My 2004 Dodge Ram has been on a once per year oil change interval since I bought it. It too will easily give me another 100,000 of service! 2012 Prius V. with 105, 000 miles and the oil still looks clean after 10,000 mile change intervals.

Car runs good with this oil and better fuel m8leage
