Customer Ratings & Reviews

I am using it in my Challenger RT plus and my RAM 1500 sport, both hemi motors and it helped quiet the valvetrain down and increased gas mileage by a couple mpgs, along with feeling a little more freed up ponies from under the hood. Will definitely keep using it!! Plus the reassurance of being able to go 6000 miles and above between oil changes knowing my motor is safe.

I used Amsoil for my race motorcycle. It's practically unbelievable that I raced that motor for over 80,000 miles. All my vehicles use entirely and only Amsoil fluids. My work truck, over 200,000 miles, runs smoother and more dependable then the day I bought it. With a clutch strong enough to screech the tires and a temperature gauge that never goes above the quarter mark on a hot Florida day. I cant thank Amsoil enough for saving me thousands in vehicle maintenance.

Great product we have a soul in everthing from lawn tractors to snowblowers and generator. Thanks Amsoil

I have been a fan of Amsoil for several years after switching to if after using Mobil 1. At oil change time, Mobil 1 would pour out like water. The first time I used Amsoil and did a routine oil change the difference was startling. The oil had maintained the same consistency, minus color, as when I first added it to the engine. Upon cleaning out the oil drain pan, the used Amsoil oil was so slick, it actually appeared to not have broken down at all. Don't buy any other product, buy Amsoil and you too will use nothing else. I use there products in all of my vehicles, lawn mowers, leaf blowers and snow blowers.

Wonderful product!! Slowly getting all my fluids in all my vehicles switched to amsoil

Use that in my wifes Honda, and their other products in my Cummings, VW & Subaru.

I use the XL 0W-20 in my wife's daily driver but use a variety of the Amsoil products in performance applications ranging from airboats to drag race cars. I am always pleased with the performance and always receive the products quickly after submitting an order.

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!

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
