Customer Ratings & Reviews

I have changed both vehicles over to Amsoil in the engines and the differentials,transfer case and transmission on My pickup and will soon put in Amsoil coolant.

Great oil for your vehicle. Wouldn't use anything else

I have used Amsoil 0w 30 in my 1998 Corvette and now I have 213000 miles on it and there are no unusual engine noises. I change my oil once a year. I have three boats 2 Corvettes,1SUV and a motorcycle all use Amsoil products. I virtually have had no powertrain problems. I use nothing but Amsoil and will continue to do so. I appreciate Amsoil technical papers as they show the science behind these outstanding fluids and are useful to convince others of the merits of Amsoil.

Excellent product and protection. After doing much research will only buy this product to protect my classic sports car, and daily driver.

Long life. Oil stays clean.

I have been using Amsoil in my vehicles since 1986. After having to change a timing chain in an earlier vehicle...it was clear ( internally ) how good Amsoil actually is. The chaincase was as clean as if it was just made. That vehicle continued on to + 260,000km with no oil leaks or other loss. Amsoil....I am a fan for life!

I love all AMSOIL products

I use Amsoil in all my vehicles, and I have many. From my Shelby GT 500 to my ATV and lawn mower. Best oil you can buy!

Been using Amsoil Signature Series 5w20 for over 18 years and have been extremely happy with it. I go 15000 miles between changes and never use more than a half quart between changes. It's the BEST.

I use this in both of my vehicles; one specs 5W-20, the other 0W-20. It gets down to -15 degrees where I live in upstate NY and I depend on Amsoil to provide effective lubrication at temperatures where other oils struggle to perform. I generally put over 250,000 miles on each vehicle, and have never had one consume any Amsoil. Totally satisfied.

I have to use the best oil. The cost of not using Amsoil will put me out of business

I do 10k mile oil changes per Toyota, but this oil comes out still clean, not even black. I have no doubt I could use it up to 25k miles.

I've used this oil in my vehicles for at least 10 years and they have performed as promised.....also haven't had any leaks from the engine ....wouldn't change!

This is by far, the best product on the market.

My 16.5 year old truck still started in the cold Iowa winter when plenty of other vehicles even newer ones wouldn't. Have to give credit to good synthetic oil.

Every oil change gets Amsoil

Extended drain intervals, combined with my bypass filter, I'd drive this thing to the moon if I could figure out how to get it off the ground!!

Good cold weather starts

made a grate difference engine is quiet with a 10% better on gas can't wait for my next oil change

07 FJ cruiser with 150k miles, as soon as I dropped this stuff in, lifter rattle was gone
