My truck has the cam phaser knocking for the last 60-70K miles. I decided to try AMSOIL so I ordered the signature series oil and filter. My truck started using a lot more oil after that. Not sure why. This time I switched to the xl series oil. Now it's not using as much oil. I'm not sure if it's a coincidence or what but I'll stick with the xl oil for now.

I've been using AMSOIL for years, and will only ever recommend/use AMSOIL products for any and all of my fluid needs.
The oil completely blows my mind. I change the oil every 5k on my '04 Mazda 3, despite Mazda recommending 3k. The oil still comes out clean, this stuff never fails to amaze me.

Since redline is around 7,400 rpm on my TSX Acura I want to make sure I'm using one of the best oils made. The car uses no oil between changes and the valve train is very clean. I have 118,000 miles on this car now and it still sounds and runs like new. I'm sure Amsoil is part of the reason.

I used to use castol oil. then my wife said "why don't you just take it to the quick oil place in town. Well, they changed hands and I did know it. I finally saw what they used in my truck. Looked like coffee. Needless to say I had a friend at work who uses Amsoil and he said to try it. I love the way my truck runs now. I am a customer for life.

I average about 6,000 miles on each of my vehicles per year. When Amsoil reformulated this oil to go as much as 1 year/12,000 miles between oil changes,I switched from Amsoil's top tier oils to this.Still great engine protection while saving some cash too. Happy customer !

I drive for Uber and Lyft averaging 1200 miles per week. Also, before retiring, I owned and operated an automotive repair facility for 41 years so I am well aware of how important lubricants are to the vehicle. Don't take my word for it, read the studies that have been performed on Amsoil products. They don't lie!

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 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.

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.

Wonderful product!! Slowly getting all my fluids in all my vehicles switched to amsoil
Reviewed by Johnny Comet:
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.

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.
