Customer Ratings & Reviews

I’ve been using AMSOIL products for more than 20 years in every car I’ve driven in that period of time and I’ve never had a major mechanical problem of any kind. My current personal vehicle, a Ford Explorer with more than 111,000 miles on it is showing no signs of wear. I will never use any product other than AMSOIL.

Great product and value. My mechanic advised that my valves were cleaned and better engine performance after using this product.

I’m usually pretty skeptical of some additives but after seeing how well it worked in my Harley and gator I’m convinced this stuff is worth the investment. I use it in all my gas engines now

All around impressive stuff and easy to use just wish it had a reminder sticker when to add the next batch. Other than keeping track odometer and writing down the mileage it’s a no fuss for win for you and your vehicle. Will for sure be using when needed again.

When I received the package the side of the box was wet with no signs of damage. When I opened the box it was obvious one of the bottles had been dropped and was leaking. You would think there would be some sort of quality control when it come to shipping chemicals. About a 1/3 had leaked out. Should have called but at the time I was to busy.

I have used this product in my 4liter Toyota 4Runner.. it cleans the injectors and keeps her running great. I have 178230 miles on her now.

Makes for some added fuel cleaner insurance!

Also used in 09 pilot . Improved performance and fuel mileage

fuel efficiency and engine conditioning.

Though the description states it works without using the funnel you need the funnel, I spilled a good bit before realizing I needed the funnel, Amsoil, please remove the "funnel not need description".

new product to me .. interested in finding results

NA

Just dumped it in the tanks to clean it up cars start easy and run well so must work

Great product showed positive results.

Used PI and my gas mileage got better immediately. Now I use it twice a year and never had any problems and always got better gas mileage than what the car was suppose to get.

Very good

Added this with my full tank bike seams to run much smoother. Highly recommended

First tank with this, still assessing

Have used it twice now and I'm getting one more gallon per mile.

First time to use this product, to soon to tell.
