Customer Ratings & Reviews

There's nothing more to say! I run Amsoil in my engine, and Amsoil ATF in the transmission, and my car has never run smoother!

I use this oil in my 2013 f150 ecoboost. These engines have known problems with timing chains and phasers. I have been using this oil consistently and currently have 120,000 miles with no rattles or failures. I will continue to use this oil on my ecoboost.

This is some of the best oil i have used in my vehicles over the last few years.

Almost 2 years using amsoil 5w30 engine oils on my Lexus and Toyota.

For years I have been a fram and either castrol or valvoline guy in all my vehicles but I bought a new silverado high county and thought I want to see what the best stuff is like so a pulled the trigger and got the full amsoil treatment with wix filter and my next oil change it was almost like my oil was just changed so now I am running amsoil in three of my four vehicles and when its time for oil change I am going to run it in there

Great customer service & a phenomenal product! Thank you AMSOIL!

Recommend alot

Excellent quality oil. A little pricey per quart but the member price makes it reasonable. A must have oil for any consumer looking for maximum engine protection.

Using in my 20118 Corvette. Better than Mobile 1.

Started using this oil and immediately started having issues With the engine and carbon buildup was way worse than with cheap oil

I have been using this oil for years in all my vehicles. I trust Amsoil to supply me with the best products to protect my vehicles. I have never had an issue with any part of my vehicles that are Amsoil protected.

First time using in a GMC with a 6.2L. Have not noticed any changes but really like the extended time between changes.

Been using 5W-50 on my 2017 Hyundia since new, because of 2.0 turbo. Has not used any oil and engine and turbo have no problems so far with 50K miles/5 years. Use it with Amsoil 15K oil filter and only change my oil once a year.

Has been in my engine for a few days now. Runs great. Can't give much scientific feedback right now. I would buy again.

The amount of power to stay with the flow of traffic is noticeable and occourse the tach reading. Can help to think a gas saving's.

as advertised love this product

I've been using Amsoil oil for a long time and that's all i use in everything including air compressor pressure washer and handguns. Its a great performer and it will never let you down.

Been using Amsoil for 40/50 years it's the best anywhere in the world. I've use Amsoil in 2016 Tundra W/ Supercharge, 2006 F-250 V10 290,000 Miles/ Chevy Cruze 2013 85,000 miles/ Toro 8000 Amsoil 15/50, Grass Hopper Mower Amsoil 15/50 Th You make a Great Product`

After we did this change (from Mobil1, so not from a regular oil, and she’s always used synthetic) in my daughters CR-V she noticed immediately smoother running as she did a few three hour road trips. I use it in all my vehicles, cars and motorcycles.

I switched my 2010 Jeep Rubicon to synthetic 5W-20 and it runs much smoother. Installed an Amsoil filter also. I will draw a sample and change the filter every 7500 miles and have it tested in a lab. Lab results will determine when I change the oil. I also changed the front and rear differentials to a synthetic Amsoil.
