Customer Ratings & Reviews

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.

I've used this product for about a year now and the intervals between oil changes continue to grow. I use my trucks gauge to see when it is needed. First couple of times I didn't really notice a difference. Now I'm on my fourth oil change and it has really made a big difference in the mileage between the last change. Great product. Keep it coming.

I started using Amsoil in my '84 Volvo at around 150,000 miles. I drive the car about 70 miles a day, hard use. I spend far less time doing oil changes and I almost never have to add oil.

Ok, I am an Amsoil customer for life... Seriously! In February when it was still wicked cold here in Maine, I was having some engine starting and idling problems with my SUV when the overnight temperatures were 15F and colder. The engine would default to a safe "limp home" mode, and I was facing some expensive engine overhaul costs. My mechanic was very sure the symptoms had to do with dirty cam phasers. He suggested using Amsoil Engine and Transmission Flush to clean the engine (including the cam phasers) and switch to Amsoil Signature Series Synthetic Oil. I followed his advice and the results have been AMAZING! After the treatment I have had zero starting problems. And even better, the rattling sound that I thought was the water pump turned out to be the timing chain... no more noise! The Amsoil Engine Flush and motor oil solved both problems and they have given my 135K mile engine new life. I plan to treat all of my vehicles with these Amsoil products, and that includes the transmissions as well. If that wasn't reason enough to use Amsoil products, when I made my first purchase I decided to register as an Amsoil Preferred Customer. I saved much, much more than the registration fee over the cost of Amsoil products at the local auto parts store on that first purchase alone. Engine problem solved and low prices equal CUSTOMER FOR LIFE!! Thanks Amsoil!
