Customer Ratings & Reviews

I have been a mechanic for over 40 years on everything from lawnmowers to autos and mostly class 8 trucks with Cummins, cats, Detroits both 2 and 4 stroke, Mack and Volvo diesels. also every type of heavy equipment from all the major manufacturers. I have rebuilt hundreds of gasoline and diesel engines. I know very well how important top quality engine oil is but I didn't think you could hear a difference in engine sound until I put 0w20 xl amsoil in my 2011 honda crv with 110,000 miles on it. I didn't expect to feel or hear any difference as I never did at any other oil change in my life but the first time I brought it up to speed on the highway it sounded quieter than usual so I done a few rapid accelerations and was convinced it was definitely quieter so I changed it in my 2012 crv with the same results. This amazes me that oil can make this difference as after thousands of oil changes in my life I had never experienced this before.

I have been using Amsoil in particular the XL series for many years. I have 2 vehicles over 500000 km. Both vehicles are running good. The engine is going to outrun the rusty body!

Great synthetic oil. Become a member and take advantage of pricing benefits. You'll be very happy.

Have been using amsoil products in my cars, pick up trucks, and motorcycles. Always pleased with performance, no problems at all. Price is fair.

I run Amsoil in all of my on road and off road vehicles.

I use Amsoil in all my vehicles. Engines run forever on Amsoil.

I have been using amsoil oil in my 2011 pick up for 2 years and change it after 20k kiss or so. I have been using them highest grade due to long oil change frequency but decided that I would go for one level down. My truck seems to like it more and my mileage has gotten better also I saved a little money in the purchase. Love it and all of Amsoil's products

Great Oil!! Hard to believe a Oil change would make so much difference but IT does! Great oil!! Our Vehicles run better and better! I tell all my friends about it.

To bad can't buy locally. One great product.

Proudly use AMSOIL products

I run this oil in my boosted truck and work trucks and can't praise it enough!! This is the only oil that i trust!!

I've used Amsoil in my previous Silverado of 18 years which was running great when I sold it and a new truck. Logged over 220K miles and never had an issue with oil leaks or major engine trouble.

I did the switch from a competitor to AMSOIL over a year ago now. This not only meet expectations but surpassed them. Love being to go long between changes which saves money as well.

Running quitter, longer and better fuel economy.

I have Amsoil in everything from my air compressors to my weed eater. Every truck, car and boat I have ever owned has used it, and my 2 street rods have used it since I built them in 1990! If you want the best, like me, then this is the oils for you! I refuse to use anything else...

I use this product as my regular run of the mill oil for my daily driver autos. We put about 2500 miles per car per month.

The perfect oil fom the mileage I drive.

So far I have a good impression but I will reserve my comment till my next change.

Have been using Amsoil for the past year and I feel a difference in my vehicle. It's runs so much better, especially when it gets really hot and cold here in Vegas.

No noticeable difference in power like some have told me, but it is still a good oil and keeps my fuel economy up. Will definitely buy again and I recommend this or the Signature Series to others. I wish they made this weight (10W-40) in Signature Series.
