I have a 30 year old Z28 and live in the heat of Florida. I use it almost every fill up in the summer, not so much in the cooler months. I notice a huge difference.

Have 2 Mazdas & 1 Honda

Quality product

works great!

Best to add prior taking a trip that is going to use more than a 1/4 of your full tank and you can actually see better mileage in your trip minder and you can actually feel better performance out of your engine. I highly recommend this if you want to clean your fuel system

I can't be 100% honest if it's actually doing anything. The only difference was the smell of gas & exhaust fumes. I've tried other brands & couldn't tell either. I hope it's doing the job as advertised it comes from a well known company that's in the high performance industry. I also use their Octane Booster that I can definitely tell the difference in boost😎

Good Stuff. With the less than acceptable gas at the pumps these days, it helps the engine run smoother.

VP injector/fuel system cleaner cost more than most injector cleaner products but is very effective. Liked that it was easy to pour in the gas tank.

Car ran better and smooth after use.

Try this in your vehicles to keep fuel injectors clean.
