I found Amsoil about 2 years ago and figured I've tried everything else why not give it a try. I bought oil along with amsoil engine flush . I flushed my engine and seen all this gunk come out of my engine It was unreal . Then I put Amsoil 5w30 oe oil in and drove it for 5000 miles . I flushed agian with Amsoil motor flush no gunk came out . It seem I had my answer other oils had impurities in them and would leave sludge in the engine and that's not good. I thank everyone should give it a shot. The proof is in the oil

As a father to 4 kids it sometimes feels like I'm a fleet mechanic. I do all the oil changes and basic maintenance on at least 6 cars so getting value for my dollar is very important. Amsoil OE is my go to oil for basic service on most of my family's vehicles. It meets the requirements of the newer GM cars and works great in older vehicles as well. I use it in everything from a 1993 pickup to a 2015 4 cylinder turbo car, everything here gets Amsoil!

I've use AmsOil in several cars now and have never had any issues related to oil, all the cars have had high mileage, one was even a high performance engine that had several times of over heating and the oil held up.

I have used this in my 2019 Lexus ES350 and the vehicle ran smoother quiter and my mileage went up. I change the oil every 5 k and this has made a drastic improvement on how the vehicle runs. I just change the oil on my Sienna and noticed the engine run smoother and quieter.

Attention to maintenance is central to longevity. Amsoil products are our choice.

You can tell the difference. My engine runs better.

This is hands down the best lubricant for any internal combustion engine.

This product works like a charm, my engine runs smoothly and feels a lot quicker. I give this motor oil a big thumps up....

after changing oil to amsoil 5W20 OE engine runs quieter and raised oil pressure very happy with purchase

Honda requires 0W20 blend or 5w20 dino. I use 5W20 full syn in a 120k CRV and 0W20 in my dad's 40k CRV. Quiet starts, free-revving engine. Premium real synthetic.

Great oil fairly priced seemed to quiet down valvetrain noise will be buying again

I have been using the OE line in my vehicles for several years now at normal vehicle change intervals. I will not pay for anything else unless it is a higher end Amsoil product. Quit looking for expensive oil and buy the best......Amsoil!

I used this oil in a Range Rover 5.0 after head gaskets and head work. After 3 heat cycles on dyno oil switched over to Amsoil product. Engine is VERY smooth and no rattle at startup. I’m pleased with this product.
