Customer Ratings & Reviews

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.

Amsoil is the absolute best oil for GDI Turbo motors. Science not opinion supports this. 2nd best oil may surprise you, It is Pennzoil Ultra platinum. But I will stay with AMSOIL for my LUXURY and Sport Cars. There is absolutely none better.Hey the invented synthetic

Great product

My Nissan Frontier 2010 is at 368000 km, and runs smooth like a sewing machine..started this oil about 2 years ago..also used amsoil oils in drivetrain...rear and front diff, transfer case, and transmission..definetely worth paying more! Should have used all these products from the get-go!

I run this in our 2017 Honda Pilot. The best on the market. On a downside still waiting on the EA15K13 oil filter

I love this oil formulation as well. I use this in my older Lexus, and it runs awesome after nearly 200,000 miles. Fantastic

I've been using AMSOIL for many years, and it's the best in my opinion. All of the formulations are top notch I will continue to use AMSOIL

I've been using Amsoil since the early 90s and it's never let me down.
