The best oil since motor oil🏌🏿‍♂️

Great oil, but not sure I want to go 25,000 miles on it. I've gone 18,000 and did another oil change. At 18,000 oil was black and I just didn't trust it anymore. I think next time I'll change at 15,000, not pushing it more than that.

i have been using this oil for years will not use any thing else

Great quality oil from day 1! Had to source oil after a track mishap back in August. Car ran great and all the numbers were spot on.

I use this 0-20 signature in my 2020 4 runner also in a 2020 Honda Civic awesome product get you some. Don’t compromise with the cheaper oils out there if you’re keeping your vehicle long term.

I’ve been using Amsoil oil and products for more than 20 years. Never a breakdown, higher fuel mileage, quieter running and peace of mind.

I've been using Amsoil 5w30 (among other viscosities too!) for over a decade. When I first switched over to using it on my turbo Miata, I did a few Blackstone oil analyses at oil changes. After 5k miles there was plenty of oil life left & TBN! My friends laugh at me that I kept my OCI @ 5k miles, even though the Amsoil could easily do 10k miles, but its cheap piece of mind! Always recommend Amsoil to all my friends & family!

My order was delivered very fast. Thank you

The best oil on the planet

This in my opinion is the best oil on the market. I have used all amsoil fluids in my 1992 Harley and just recently bought a 1988 iroc that I will be changing all the fluids to amsoil.

tried this and some of the competitors 5w-30 synthetic oil, this stuff outperforms everything else by a mile.

Good solid trusted brand, with their preferred member discount it is very well priced.

Totally worth it. My engine runs way smoother now. I can even feel a difference when I downshift the engine doesn't seem to Rev as hard when I get into gear. On top of all that the highest average for my mpg has increased by a whole mile without having to chamge the way I drive at all. 100% worth it!

Best synthetic oil on market with best prices

Outstanding Products and Customer Service. Will not use any other oil products.

Wish I'd started using it along time ago

This oil hands down is my favorite and I will only use it why?because it is the truth!!!

I put this oil in my 2010 Subaru with 125,000 miles on it and I just changed it a few weeks ago. No issues it lasted a year and performed flawless! I can’t wait to put Amsoil in my 2021 Tundra! Just waiting for the free dealership oil changes to expire!

Our third vehicle uses 0W-20 synthetic Amsoil and nothing else! great gas mileage too!

Only synthetic oil I have used in both our vehicles for years now and am amazed at how clean it looks after an extended oil change!
