Customer Ratings & Reviews

I have using Amsoil since 1979 in all my vehicles. I had a 1981 Toyota 4X4 SR5 that I used Amsoil from day one. I had to rebuild the tranny at 30K & 60K miles (no fault of Amsoil-Toyota used a Celica tranny that was very underrated for the 4X4). When I removed the parts the syncos and gears looked like new. The main problem was the input bearing was to small and chewed itself up at 30K and 60K miles. Never bought another Toyota since they would not honor their 30K warranty.

Great product and gives your vehicle a clean out and a mileage boost.

Put this in all of my cars and they got better gas millage.i recommend this product to all of my friends

I used this on a company car that only drove short distances around the work site (Orlando Airport). I used this product on my personal car and liked the results so I used it in this company car and WOW!!! The results were phenomenal. No more rough starts. No acceleration lag. It was like a totally new car.

I use this product every other month and it keeps all my vehicles running great.

Excellent

I put Amsoil in everything I own. I found that my vehicles and equipment last longer and perform better. My vehicles gfet better MPG, and handle all kinds of wear and tear.

I use this in all of my vehicles, but I really know it works when I had a motorcycle that was used very little. The carbs were gummed up and it wasn't running right. I really didn't want to tear the carbs apart, so I ran a few tankfuls of gas with PI in it through and it cleaned up the carbs. The motorcycle now runs right!

Wifey left her flagship Mercedes Benz unused for a long time and the engine was really rough. I poured in 2 oz per tank until the idle was smooth. I recommend putting a little in at a time in case injectors get plugged with a whole bottle. So start slow for the first tank and then increase. Lovely stuff.

Install this in your gas tank and your milage might just incress .

Have used this product for years have never had any fuel system problems.

I've used amsoil ever since I bought my car new. And the fuel injector cleaner joined with the oil has kept the car running great and like new.

If used as directed it does a great job

Good product thanks amsoil

WORKS VERY WELL

Used in a Scion tC, cleaning agents inside work very effectively. Can feel power being restored to the car over the course of the tank of gas. I use 3/4ths a bottle every 5000 miles to make sure everything is clean and pristine.

My Honda Accord, EX-L had a hesitation problem for some time. I tried other additives that did not work. When I tried Amsoil Gasoline Additive it worked and is still working. Next treatment is at 4000 mile after first use.

Had a slight hesitation after shifting into 2d gear for the last year. Added bottle to full tank of gas and by a 1/2 tank the hesitation was gone and has remained gone.

I use P.i. every 5000 miles because it's easier to track that frequency on my odometer. I have over 130,000 miles on my 2007 Silverado and have experienced zero fuel injector problems.

Am using this stuff every oil change. Will update as I go
