I run Amsoil in my truck and snowmobile.

Never in doubt...

My car runs way better and bring out lots of power

My bmw 328 run super great ... incredible in cold temperature....thanks

Hands down the best oil I've ever used in all my trucks and suvs I saw improvements in fuel mileage Lower rpm at idle Cooler temperatures I will never use anything else but Amsoil

Signature Series oil is unbelievable. I have had multiple vehicles with two hundred to three hundred twenty-five thousand miles on them and Amsoil keep clean like new. I also have 22 and 38 year old tractors that use no oil.

I use Amsoil Signature Series in all of my cars, from my truck, daily drivers and four various Porsche models. Nothing better and I will never switch!

It's expensive but for protection it's worth it. It seems to be the best wear protection of any oils I've tried in my various vehicles

Use it in all my cars, only oil that my cars don't drink like water.

I have a 2016 Camaro ss that started to burn a little oil with the valvoline full synthetic I was using. I started using Amsoil and two oil changes later the car hasn't burned a drop of oil and the oil seems to hold up a lot better. I will only be using Amsoil in my cars from now on.

Been using this oil for years.

Switched over to Amsoil in my F-150 with the 5.4L Triton. Switch over with just over 100k on the truck. I did use the engine flush per recommendation. I did notice that it is quieter on start up at sub-zero(-20f) temperatures. I have oil pressure at turn key! A must have in the Northern area.

I use this 5w30 in a 2006 explorer with over 200,000 miles and have no issues.

Good for my older vehicle

Best oil in the market use it on all our cars!

Best oil on the market. Buying anything else is foolinness.

The type of oils and fluids that go into my vehicles etc hands own #1 in the business you want the best from your vehicle then you have to use the best.

Excellent oil, I use Amsoil in all my mechanical equipment and they last a long time!

I am a relatively new user, but the research I have done has all been positive and enthusiastic, both from friends and online.

I find its a good product except i am disapointed about one thing. My friend's father was a distributor before and he was selling the serie 2000 that was better. The price is not lower
