Customer Ratings & Reviews

Used it for the girlfriends civic hybrid. Keeps the eningw running smooth and happy and keeps me happy knowing it has the best protection in it especially with it's stupid stop and start garbage.

Very satisfied with the product and will always use it.

For over 12 years Amsoil is the only oil that I use for all of my cars. I can't really say if it has helped my mileage but just from the comparison specks and the way my vehicles run is proof enough for me. Better cold running, smoother idle, and longer change intervals are some of reasons the higher cost is justified.

I've been using Amsoil products for about 17 years now and I never cease to be amazed how it makes my high milage 05 prius with 322,000 miles run like new! I use the Signature Series 5w30 in it and in some of my other vehicles I use the XL for seasonal oil service! I've tried all those other brands.And they can't compare.I would say, I am a completely satisfied Amsoil fanatic and,So glad of it. Thanks Paul

I have about 2000 miles in this oil change in my 392 hemi. Most have been interstate miles and the rest are me driving like I stole it. And the engine hasn't blown up, can't ask for any better of an outcome.

I use it in my wife's Tahao, it is high mileage so a synthetic works great for me. It decreases the frequency of oil changes and improves engine performance.

I have nothing but good things to say about amsoil xl. It protects engine parts and holds up for the entire amount of mileage that It states. I use it in 3 vehicles and am quite pleased with its performance

2 of my cars have over 240,000 miles on them. I would never use anything other than AMSOIL! Nothing comes close. In my 1997 Suburban the ATF has not been changed in 10 years, still proving great protection!!

We use Amsoil products in all our vehicles. We like the benefits of synthetic oil and dealing with Amsoil is awesome.

I've been using Amsoil for over 10 years now in all my suv and trucks It's the Best !!!

I purchased my Wrx new, new the boxer engines and what oil to use I was recommended to amsoil co-worker said it would be perfect for the boxer engine, I have never had any oil consumption problems always runs great been using it for 5 years and love it. I also use amsoil in my transmission works flawless.

I put this oil in my 2012 Chevy Volt and I noticed a big difference in the performance of the engine it got very quiet and ran smoother

Great product. US Amsoil in all my stuff and most of my friends use it too

I run it in my truck and suv

I use it in 2011 jeep compass,and 2004 ford freestar .

Consider this. 6 to 8 dollars for a quart of oil seems high till you understand it is protecting a vehicle that cost 10 to 50 thousand. Then it sounds cheap.

I use this product for all my vehicles and will continue to do so.

Switched to Amsoil for my new vehicle based on its' past and current reputation. Hoping for a long ownership, the future will tell.

Used in my 2014 toyota Camry and so far so good!

I will continue to use Amsoil products.
