Best engine protection in an oil available! Change my oil once a year. Easy!

I have used only Amsoil in my 2005 Toyota pickup. I now have 205000 miles. I have never had a problem and still us no oil and have no oil leaks. Change every 25000 miles.

AMSOIL, the single best lubricating oil on the planet! The End

I use amsoil don all my vehicles

In my personal auto's

I can't think of anything negative to say

Made the engine run so quiet

Nothing really comes close to the performance of amszoil. I used for 15 years thsn switched the charger surpassed 1146000 miles yes million. After having trouble finding goid oil im back permanently...

You can put any oil in a new engine and call it good. I run my cars 200k+ that's when oil matters. Amsoil cools,cleans, seals and lubricates better than anything I have used and I have tried them all.

I drive for work 1,000 miles plus a week, I use Amsoil in my car along with my wife's... I have right at 300,000 on a 2012 Kia Soul and the motor is just as good and clean as the day I purchased. I save money as well... using any other other brand is crazy

Best oil on the market.

It goes in my 3.6VVT and my 5.4 2V and does wonders for engine noise, oil change intervals, and most of all performance! It doesn't matter if it's a modern engine or not so modern engine, it Works!

Run it in all my vehicles. Not only engine oil but the best transmission and gear oil ever made available for the consumer! Independent tests dont lie...if you become a preferred member for $16 a year, all their products are cheaper than mobile one and pennzoil.

I have used AmsOil exclusively for over 20 years. It's the best there is. My truck loves it.

It's the best hands down! Some people think it's all the same ! There wrong! 25,000 miles you can not bet it.

This is the best oil I have ever used in my Ram 1500.

I use in my 1999 Corvette because I like to use the best, and also in my 2016 Dodge pickup.

First thing I noticed right away was how it make an already smooth engine even smoother and quieter. I've always used Mobil 1 advanced 15k oil and have heard nothing but great things about Amsoil. A co worker of mine had a teacher in tech school who used to rebuild his engine every year after racing season. He switched to Amsoil and hasn't had to rebuild it in 5 years. As soon as I heard that I was sold. If you want the best Amsoil is it.

I use this every 5k miles. The car runs smoother and quiter than my previous oil changes. It doesn't lose it's slickness. I'm overall satisfied with this oil.
