Best on the market

No oil beats this. The oil station I change it on my vehicles loves Mobil one. I try to get them in this brand Amsoil. I always bring my own oil. Thanks for a great product!
Excellent product- when I need my engine to go the distance this is the real deal! Never had an engine go bad using Amsoil!! That’s hundreds of thousands of miles in all conditions!!
Love the products but only thing I have an issue with is the lack of stock on and oil filters! When I order a oil change kit I don’t want the wix filter if I wanted that I’d go to the local parts store
Bottom Line
Yes, I would recommend this to a friend.

Great for hybrids

I have been using this in my 2024 Kia Niro hybrid since new. With the on / off operation of the gas engine I wanted to have the best protection possible. I put on about 5,000 miles per year and change the oil once per year. 0W-16 is a thin oil so I want top quality. So far it has been great.
This product claims a lot so far using it. I don’t see a big chain difference motors a strong motor a 57 hemi Chrysler motor have used many products, including what factor recommends have a couple more weeks of Used on the Oil after I run a few test on the Use I’ll give a better feedback if it has a better feedback.
I started using this oil in 2009 in a Toyota Avalon with 230k miles. That same car now has 456k miles and runs as smooth as a top! I run the oil for 20-25k miles, changing the filter in the middle of the interval. I would not put anything else in my vehicles!
Bottom Line
Yes, I would recommend this to a friend.

I have been told this oil is the best of the best. They say I can go 20k on an oil change. Do I trust that? Not really. But I try to use the best products that I can afford. Do I see or feel a difference? No. I just have to take their word on it.
Bottom Line
Yes, I would recommend this to a friend.

I use this in my Granddaughters Kia. She loves the fact of only one oil change a year. She is really busy with work and school . She does not want to be bothered a few months with an oil change!
I have been using Amsoil 5-20 in my 2014 150 and my wife’s 2013 Eacape since we bought them, 2015 & 2016 respectfully. The Escape will lose about a qt a year and my truck loses none! I swear by Amsoil, like a famous saying, I use that S!|t in everything!
