Customer Ratings & Reviews

Sure! Here's a brief example of a review based on a short experience using AMSOIL injector cleaner: "Recently, I decided to try out the AMSOIL injector cleaner to see if it could improve the performance of my car. I followed the simple application instructions, adding the recommended amount of the cleaner to my fuel tank. After using it for a few tanks of gas, I did notice a slight improvement in my car's overall performance. The engine seemed to run smoother, and I experienced fewer instances of hesitation or rough idling. Additionally, I noticed a slight improvement in fuel efficiency, which was a pleasant surprise. One aspect I appreciated about the AMSOIL injector cleaner was its ease of use. The bottle came with clear instructions, and pouring the cleaner into the fuel tank was a hassle-free process. In conclusion, based on my short experience, I would recommend the AMSOIL injector cleaner. It provided noticeable improvements in engine performance and fuel efficiency. Just be aware of the strong scent it leaves behind. Overall, I found the product to be effective and easy to use." Remember, this is just a brief example, and you can expand on each point or share more specific details based on your personal experience.

Had a high idle in my 1990 Mazda Miata that performance improver lowered after pouring this into my gas tank. I believe the engine is now running cleaner and stronger. Way better then store bought products like Lucus etc ..

Fixed a mild skip in my 03 Silverado 5.3. I’ll be using this at every oil change and fuel filter replacement.

I put this in a 2012 Mercedes GLK 350 that has 120,000 miles. We had loaned this vehicle to the father in law and it did a lot of sitting…often a couple weeks at a time between startups. We got the car back, added a bottle of this magic, and in no time the idle was smooth as new and the car wasn’t downshifting as much on the open road. This is the only time I’ve ever used a fuel additive and actually felt a difference.

I have used your synthetic oil for years I just put the new synthetic oil for car with 100,000 miles. I have 2012FordFusion with a 3.0 l V-6 with 97,000 miles and I just put in this new oil and we shall how much the engine will like the new oil. It run like a top and know I will recommend this synthetic foil to any one that wants the engine much longer thanks for the best oil for all gasoline engines

I have always used PI as a preventative solution to combat combustion deposits and a fuel system cleaner. Must be working as I have not had a fuel issue in 15 years.

Put it in a full tank and truck ran smooth idle smooth and just great results, highly recommend

I noticed the difference the first time I used it about a year ago. Give my engine better performance.

Truck runs better increased mileage great product.

I've used this product for a couple years with all my vehicles. I use it and run it through right before an oil change to make sure everything is clean as possible when the oil is changed out. Have had no issues with this, and pleased with results.

Great feel additive using all my cars

I am glad Amsoil has this additive for the gas, Performance Improver is exactly what it does, hands down.

I add this awesome product went from 37 mpg back up to 40.5 mpg on my 4th tank of gas now and it's staying in the 40mpg range 2017 Toyota Corolla 83,000 miles

Second time using PI. Fuel economy always goes up during and after its use. I add to tank at each oil service around 5K miles.

The PI does a good job at cleaning your fuel injectors and the heads in general.

Yet another good product by Amsoil

I used this product in my Nissan Murano and after buring about a 1/4 tank of gas. My motor ran quieter and it was quicker when accelerating and my mileage has increased by about 4% and I am loving it

Worked well in both 2014 Silverado and Honda

I’ve used this product for years in an ‘06 Tundra and ‘09 CRV and vehicles continue to perform as new. Highly recommend using this at least twice a year.

Performs just as it should.
