So does it work? I have no clue. I ran several of these additives through my vehicles, but Im not 100% convinced that there was any improvement in the performance or mileage of my vehicles. I added 1 bottle to a tank in my Cayenne S before visiting friends in AZ. Another bottle while filling up again for the way home to LA area in CA. Mileage didnt increase at all, ( 23mpg hwy) and performance didnt seem to increase either, but maybe my Porsche was already max clean from using name brand fuels. In any case case, I tried it in a non DI vehicle, ( Porsche Boxster S) and it didn't shine there either. So as a preventive maintenance measure I'd say go for it, but in my case, I have not notices any difference in performance whatsoever.

I use this a couple of times a year after an oil change, seems to put the pep back in the step!!!

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.

Use this in our Camry LE every 2000 miles or so Increases mpg and engine runs smoother

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!

Although this product does do the job, you’ll pay handsomely for it & there are similar products on the market that are just as good for less.

Tried this product on a whim and it worked great! Enough so that I purchased multiple bottles of it again.

Usually everything goes well and deliveries are within 3 business days which is awesome, but I have been waiting for my order now for two weeks and no sign of it, had to cancel service on vehicle because order was a no show, no tracking number to check on status just that the order was shipped. We don't live that far away so I am not happy and very disappointed.

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
