Engine runs smoother and fuel economy improves. Even in high rev, high horsepower vehicles

Ams oil is the best motor oil on the market today.

I switched to the 10W-30 because my F-150 5.0L has always used oil and I’m trying to reduce oil consumption. So far it has made a huge difference over the 5W-20. I feel the 30 weight is definitely the way to go. Great oil !!

Great performance, great in my wife’s Acura. Highly recommend AMSOIL.

I have been using Amsoil since 1994 and it has worked flawlessly.

This product works as claimed, I only run this in my 30yr old Jeep and my family car

Noticed an immediate improvement in engine performance in the Mustang and my 20 year old F150. Valve clicking vanished in the old truck. Changing all 3 vehicles over to Amsoil!

Keeps my truck’s engine clean. I’ve noticed that as my engine gets older (113,000+) the oil I’ve consistently used in my truck has been free of burnt, or thick sludgy oil. My truck runs great, and I’m sure I’ll get another 113,000 miles out of her.

I know that no corners were cut in producing this high-quality oil. This oil has kept my engine happy and almost wear-free because of its chemical properties. I can't wait to do a partial tear down of my engine to see how well it performed because of performance upgrades. I will continue to purchase.

I purchased a 2018 GMC and from the first oil change nothing but Amsoil has gone in! Best oil around.

I’ve used Amsoil for years in my various pickups, have used in my street car as well.

I have a 2007 Mercedes-Benz C230 Sport, and this is the only oil that I have ever run in it. I’ve never had a motor problem.

Good oil so far first vehicle to run amsoil. But 44k and running. Mostly high or idle.

I have been using this oil for 6 years with absolutely no issues. It has made the engine quieter and has great cold weather starting. Absolutely the best of the synthetic and all oils.

The oil protects the engine against severe wear in all types of weather conditions, I will strongly recommend this oil

I have been using Amsoil products for over 15 years. It all started with the 100 to 1 two stroke oil. Never had a problem. Had a Lawn-Boy 2 stroke mower that was 30 years old and it still had the original spark plug in it. Took it apart to clean the exhaust port and it did not need cleaning.

Amsoil Signature Series 5W-30 is by far the best oil for my LS1 engine! The engine runs quieter and promotes less valve ticking noise! This oil along with a Wix XP filter or Amsoil filter is the answer for extended life to the Trans Am!

Appears to be a good oil...

It took a few weeks but I could really tell the difference in the motor , Especially when idling next to a window

I have used Amsoil products for some time. I used to live in the northern parts of Canada, and switched to synthetic oil due to the extreme cold. I tried numerous name brands, but found amsoil not only provided great cold weather starting but was the only product that made a noticeable gain in the fuel economy of my vehicles. It is well worth the slightly higher monetary investment.
