This is the first time I'm using this product and I notice in the end of my tail pipes there's a bit of black carbon in my chrome pipes, that means it's cleaning not just my injection it's cleaning my catalytic converter has well. Kia 2021 stinger GT limited 3.3 GDI turbo

I added this after engine flush and oil change. I could feel the difference right away. I highly recommend this product

I’ve used PI on everything that has a gas engine after lots of mikes I pull the injectors and inspect the cylinder bore and piston you would believe what regular use does for keeping them clean

I was surprised that after Just 1 bottle it stopped the hesitation when starting out at slow speed. I now use a bottle about every 4 thousand miles.

Anytime my fuel injected, turbo Buick starts to idle a bit rough, I add one of these at the next fill up. Smooths it up, and I also notice a mpg increase.

Saw huge mpg improvements for the first co up 3k

After I put this product in my car I noticed an improved throttle response.

I tried other Amsoil products so why not this?

I have run this gas treatment 2 times in my 2017 2500HD. I honestly have noticed no difference in motor out put, Horse Power or better MPG. I will try this in my Ford Ranger to see if there is any noticeable difference in the near future. If I could get my money back for the 2 bottles I purchased I would. This product might work for others but I was not impressed.

After use one bottle in each vehicle I have noticed our engines running a little smoother. Very happy.

I've used PI both as a maintenance product (every 4,000 miles) and as an emissions passer (annual NY state inspection). Works as advertised.

Made a huge difference even after the first treatment.

Similar to the upper cylinder lubricant, this stuff is a great fuel additive. I've also used it in three vehicles and the results are amazing. Regain in HP and smoother idle are easily noticed as well. Highly recommend.

Have not had enough time on this to give a good account

IT WILL CLEAN YOUR ENGINE LIKE NONE YOU HAVE EVER USED

Incredible product! Lives up to its description in every way.

Been using this gasoline additive in my 2011 Honda CRV every 3000 Miles and works great. Take care of your car and it will take care of you.

I use it right before a long road trip

Use it and you will start to believe that not all oils and products are made the same

I used this product second time on my 2009 toyota rav4 with 260, 036 miles. I feel significant difference in acceleration, responsiveness and economy. M gonna continue to use and you should try it.
