Customer Ratings & Reviews

I am not a chemist or engineer, so I cannot speak as to what's inside the bottle. However I am a mechanic and can speak as to what's inside a engine, transmission or differential. I've used Amsoil on and off over the years alone with other bands of synthetic and conventional oils. I've never used anything that didn't work. However, I've found good oils last longer. Being a fleet mechanic I change a lot of oil and get to see what it looks like under abuse. Amsoil always holds up. That's why I use it.

I have been using 0W20 in my 2014 Mitsubishi Outlander since it was new. I have noticed no loss in power or performance and my dealer comments on how clean my engine is!

Seems like good oil; we'll see, when the odometer turns 400k.

Keeps my truck running smooth and strong. Won't use anything but amsoil

I use Amsoil motor oil in both of my vehicles and I use Amsoil oil 20-50 for my Harley.Excellent product tons of research done without a doubt the top of the oil food chain.

use I 2 Tacomas

I ran a purple brand for 10 years. I've always heard good things about Amsoil so after feeling like the product quality of my previous brand was going downhill I decided to try it out. As a preferred customer I can get Amsoil cheaper than my previous brand. My truck runs smoother with less engine noise. Great product with superior performance!

I use it in my daily (2018 Jeep compass) and my project trucks (98 ram and 83 s10)

I have tried many types of oils and read a ton of reviews, which can be hard to decipher with everyone giving their personal comments and feelings. But hands-down without a doubt Amsoil is the best product out there, tested over and over again. I know this is the only oil I will trust in my vehicles. Now, I wish Amsoil will create their own waterless radiator fluid so that everyone will enjoy all the fluids in their cars are coming from a trusted source.

This is just one of Amsoil products that I use. I have used Amsoil synthetic oil for 20 years, and every time I get a new or used vehicle, I waste no time in switching the crankcase to Amsoil. I have 267,000 miles on my 2005 Camry, used Amsoil since it had 300 miles on the speedo, and it's still purring like a kitten and not burning oil. I am a very satisfied customer.

So far so good. Ben 3k miles since change. Oil still looks clean clear and new.

I have used other oils but was sold on Amsoil after a cross country trip where unbeknownst to me all the coolant leaked out of my vehicle. I never noticed because my engine never got hot. I drove all the way through the Great Smokey Mountains and hot Texas heat without my diesel engine ever getting hot even though I was towing a trailer. Great Stuff. Thats the kind of performance I like.

I run this in my Jeep JK. The Jeep runs smooth, quiet and cool. It's a comfort thing knowing I'm protecting my engine with Amsoil.

I have a 2009 ZO6 Corvette that is notoriously hard on oil, however the Amsoil is standing up to the abuse, and has also lowered operating temperatures by 6 degrees. Very happy so far.....

i run this in my truck! won't put any other oil in it!

Better than regular synthetics. With the Preferred Customer discount, it works out to slightly less expensive than the store bought brands.

Use it in everything I own. Great stuuff

I use Amsoil on my 2 cars and my deisel boat. I've never had a reason to question its performance. So far, so good.

This particular viscosity I've only been using for a year in a new car. However, I've been using Amsoil products in everything for probably close to 25 years. My last Jeep Cherokee I bought new and had 268,000 miles before selling it with no engine issues and the previous Jeep closer to 300,000 miles. Same deal, still passing inspection, no engine issues. I also use the compressor oil in 2 large air compressors at work. Both came with there own MFR synthetic oils. After 5 or so years they started seizing on me. I switched to Amsoil and haven't had a problem in either one for close to an additional 6 years now. Nothing but Amsoil.

I run Amsoil in my truck and in a buddies truck. On both vehicles we have seen improved fuel economy and better cold starts. The truck has no issues starting in -30°f and below even when left unplugged over night. I have seen increases all over the board.
