Customer Ratings & Reviews

Have always used either Amsoil or Mobil 1. Both are great oils and and every other oil change at 7500 miles in my Toyota Tundra, Lexus, Mazda and Honda CRV. I send the old oil off to Blackstone for analysis. The analysis of Amsoil and Mobil 1 both always show excellent wear and Blackstone recommends that I could go much longer between changes. Thus I usually buy Mobil 1 because I can get it at Costco, don't have to pay shipping and this makes it much cheaper.

Have used synthetics in all my vehicles for quite a few years now. You can tell the difference the first time you change over to synthetics.

I use this in my Chevrolet Silverado and Kia Optima Hybrid and follow the manufacture recommend oil change interval.

Love the whole product line, I use amsoil in everything I own down to my power washer. Never fails.

Love the Pease of mind of only having change my oil twice a year. My 2005 Ram is approaching 200K miles and still running strong.

I use these products in all my vehicles and marine apps.

Plan to use Amsoil for the life of my vehicle to help it last a very long time. It's the best available.

Love this in my truck, only having to change it once a year is awesome.

All my vehicles run on Amsoil. Just something you do if you want them to last.

Very easy to look up vehicle or toy. It's very convenient for me to order oil and filter and send it to the house.I use it in all my vehicles also my sons trucks.

I use amsoil in everything, it has unbeatable protection and as a preferred member it comes at a great value

The XL gives me another choice. New vehicles get the premium oil but older,lower useage cars can use the XL

I am glad that ams oil asked. I drove my car 12,000 km in 7 months with the same oil and in top of that there were minus 24 celsius degrees outside, job well done.

Excellent oil for those looking for a bit more protection that regular oil. Excellent in high milage vehicles especially.

I use there motor oil in my 454 in my 92 suburban along with there fluids in my diffs. Eventually will be switching to the trans fluid too. And I run it in our kia made the engine run alot quieter then the factory oil

This is the Oil I use to put in the other 3 family Kias . 2 collage kids and wife's Sorento . One spotage turbo and one non . The mileage intervals help poor ol dads pocket book .

My vehicles run better, the engines are clean

I started using Amsoil in 2000 when the garage I started working at sold it,haven't used anything but since then. It's a wonderful product and I love the longer service intervals for an oil or tranny change especially since I don't have a lift at home

Got this for my 2007 Pontiac Solstice 2.4L that's been turbocharged with a custom K04 turbo kit. Engine runs great!

Have been using Amsoil in the Mark LT since 2006 and it has 130,000 miles and engine is good and does not use or leak oil.
