Customer Ratings & Reviews

I'm a trucker by trade and I was traveling through Pennsylvania when a Amsoil distributor passed me. What caught my eyes was the slogan, "The first in synthetic, the last motor oil you will buy." I got the distributor attention and he pulled into the rest area and to make a long story short, he placed his hand on his engine, I was completely shocked and sold. It is the best.

I do lots of stop and going here in town with my 2011 F150. Give it a try, you'll see and feel the difference with the performance

Every spring I use Signature Series in my cars and motorcycles. Before the next spring the cars will need 1 to 2 quarts added. The XL oil provides an economical answer to a short term need.

Use amsoil in everything.

Worry free oil

I use XL in my 2013 GMC Sierra and My 2011 GMC Terrain, The 5w30 keep them working like new!

Both my 2001 honda accords seemed to run smother after first oil change with amsoil

I've used nothing but Amsoil in my vehicles for many years. Wouldn't change.

I prefer to use other products that are not as expensive

Oil doesn't break down as fast as other oils

For years now I have used Amzoil. The Jeep I have has a high performance Chevy 350 that had cooling issues. A few times it went well above normal temps. The oil did not break down, no damage was done to the engine.

Amazing oil! Has troubles with my silverado having lifter tick when it was cold out. After I used this oil and the amsoil filter,the tick went away and has not come back at all even on the coldest wisconsin days! Definitely shocked and amazed

I visited your booth at a Goldwing Rally and signed up. I used the Motorcycle 10W 40 in my Valkyrie and it shifted so much better and over 5k miles it didn't change. Made a believer out of me. I have 3 motorcycles, 2 cars and a conversion van. Using Amsoil in all of them.

I use Amsoil in my vehicles, Harley, and my zero turn mower because it's the best oil and keeps my engines running smoothly.

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

Great oil. Superior performance. Recommended
