Customer Ratings & Reviews

Use this in a bunch of different cars year round. Works great! Quiets down the engine compared to name brand oils. Lasts longer, better wear results then big brands. Worth the money! Fantastic oil.

My truck ran good before but now its great

I use this on a V8 that is supposed to get 10w-60 but I really don’t see a reason for it since that second number shears down fairly quickly. This is quite stable after a year. I only put on 2500 miles annually so it’s nothing.

After using mobil1 for years, i noticed it wasnt lasting as it should and it would let the valvetrain make more noise. So i decided to try this in my freshly cammed L99 with a GPI VVT SS2 cam. Now, theres absolutely no valvetrain noise, my oil temps are actually lower, and my pressure is more stable. even on the hottest days i hold 28psi hot temp. Ill stick to using 8qt of this stuff from now on.

Put this in the 3.6L pentastar in the jeep, and boy did she get quiet. mobil1 and valvoline would always let the top end sing its song. Now, Shes nice and quiet down here in FL.

I’ve been running amsoil in my 2019 f-150 2.7L ecoboost since new would would different recommend this to anyone with an Ecoboost engine truck has 90,000km changing the oil ever 8-9k i do about 45,000km a year and this keeps the truck running like new. My last truck 2016 5.0 f-150 had 150,000km on if all on amsoil with no problems

Changed all my oil in the truck to AMS

it's good so I buy it, at least until I find one better... they want a bunch of money for it so if they keep making it good then ill pay. "A" stands for America and if u don't agree then get out.

I wanted to put the highest quality oil in my truck and only changing it once a year was something I really liked. I changed the oil at 4,000 miles also used the Amsoil filter. Something that I didn't expect is that the engine runs better. It ran good before it's like new with only 4,000 miles. But the engine purrs like a kitten. It's amazing to me that oil could make that kind of a difference. I'm telling everyone.

Use this oil in all my vehicles except old blue which I use 10W-30 which is what the owners manual recommends. I think Amsoil is the top of the line in synthetic oils. Has protected my engines for a few years now.

My son had not kept an eye on his 94-F150 and ran it out of oil. I found it because the oil gauge dropped to 0 when I accelerated, then back up. After adding 9 quarts of oil it ran like a charm. 2 years later replaced transmission, but engine runs great. I swear by this oil.

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.
