Rislone Hy-per Fuel Fuel Injector Cleaner Concentrate (Pack of 12),4701-12PK

Fuel injectors need a cleaner/booster now and then. This one seems to work well. Thank you.

I have a 2019 Ford Explorer that fired code P0302 for a misfiring cylinder. Trouble shooting with a replacement spark plug and replaced coil did not fix the issue. Before taking it in to the shop I added 1 bottle of the cleaner to a half empty tank and drove around for a few miles. Check engine light went out and code was cleared. Will watch it for a few days but signs look good that I had a blocked or partially blocked injector that this resolved.

I had a motor sitting in the garage for a 16 months before it was installed. This stuff broke down the shellac and greatly improved my gas mileage.

good prodct

My Benz 300 was having symptoms of my fuel injectors needing a cleaning. I took it to my mechanic and he said everything looked perfect but suggested I use this to clear up the symptoms. I put this in a near empty tank and it cleaned up the injectors INSTANTLY. 10/10 would use again!

This product works quickly and better than other brands, hands down. IF you're having an "engine light" due to cold start, or rough idle and you suspect dirty injectors, use this product! IF it's simply dirty injectors, this stuff WORKS

Sirve Pero no se siente tanta su acción

I have a 2005 Frontier with over 200,000 miles on it. I rarely drive it now, and it was noticeably lacking power that it used to have during acceleration. I figured the fuel injectors were clogged (I do regular maintenance on it). Since this product was pretty cheap, I decided to give it a go. After I ran it through the tank and drove enough to do what it needed to do, I have noticed an incredible amount of acceleration power that this truck once had. Very impressed.
