Customer Ratings & Reviews

Mustang GT running a little rough. Ran treatment and it smooooothed out and runs stronger.

Works great has never failed me.

I have been using PI for several years in both of my Corvette ZO6s. It eliminates carbon buildup and helps the engine run smoother with regular usage. I use only Top Tier gasoline. It is very noticeable if I run out and don't add PI every third or fourth tank of gas...I have a 2006 and a 2015...both cars react similarly to the additive. Plus, both get a little better gas mileage, too! I will not run them without using PI regularly...very satisfied customer.

I notice about 1.5 to 3 MPG increase for 3 to 4 tanks after using this additive.

I used this in my truck which runs great. I used this mostly as a preventive maintenance item. I did not see any improvement in performance but I will definitely use again

Always is good to know the fuel injectors get some cleaning when this is in the tank.

HAD A ROUGH IDLE AND HESITATION PULLING AWAY FROM A STOP AND DECIDED TO PUT SPECIAL JUICE FROM AMSOIL IN GAS TANK! CLEARED EVERYTHING UP AND NO PROBLEM NOW! IT MUST HAVE CLEANED UP SOME CARBON BUILD-UP SOMEWHERE IN THE FUEL SYSTEM!

I could tell the difference on the first bottle excellent product highly recommended

I use the PI in my lawn maintenance vehicles when I forget to treat the gas b 4 I put them up for winter! Put it in the can and fill my tanks and everything smooths right out with the first tankful!

I was having trouble with my truck running ruff so I tried this even though I don't normally use additaves. This was because I trust Amsoil. It worked great, I noticed the difference within 30 or 40 miles. I plan on adding this to my tank every oil change moving forward.

Good

My vehicles run smooth as new after 156,000 miles. But, I use Amsoil fluids and oils everywhere in my cars. I know my vehicles are protected.

You have to use it to know what it is. I used it for 16 years on my Intrepid and ran it for 567 KM. without any service to the injectors. I would have run that car to million if it had not met with an accident.

Just put in my gas tank, so not really able to comment yet

I think is a good product definitely has my vehicle running a lot better

My car’s 16 years old with almost 150k miles. I was averaging 20.5 ish mpg, i put a full bottle in my tank at fill up and after that tank I’ve been seeing 23-24mpg and my car runs incredible. Would HIGHLY recommend to anyone wanting to treat their car right.

Even though my vehicle takes 91 octane, this treatment improves my gas mileage.

Man this restored the MPG and horsepower in my moms 2010 Camry LE 2.5! It’s made my BMW 428i get better mileage as well and in my other car, 2018 Camry SE, it’s better than the EFI additive they put in at the dealer when they do the service every 5k miles. Paired with the OE 0W-16 oil from AMSOIL as well, I’m getting almost 45 MPG in a petrol car! Amazing results in all my cars and the best fuel cleaner on the market.

Truck runs smoother and mpg’s have improved in the first use of this product!

Your Amsoil gas additive works very well considering a lot of gasolines have a lot of impurities and some water in their gasoline's ! Personally I use higher octane in my gas tank and a name brand gasoline. that way it helps clean fuel injectors stay clean. Your product cleans my fuel injectors and impurities in my engine and I also use a synthetic oil. Thank you Amsoil Gas additive high quality product. I highly recommend this putting in your gas tank at least once a month or every two months. Especially for those people who are on the budget and use regular gas.
