I've used just about every store bought "cleaner" type product with underwhelming results. Needless to say I went in with low expectations because of that. After using the injector cleaner per instructions and adding the tune up to my gas tank I've noticed a slew of improvements on my vehicle. My mystery miss-fire is gone, smoother idle and acceleration, and I even added a bottle to my transmission and have noticed an improvement in shift points. This stuff works. 205k miles and going strong.

used to clean sludge from a 96 ford ranger 2.3l with 300k miles with one tune up and the fuel injector cleaner worked wonders. no more piston rings blow by and sucking up and burning oil on decel. used the other tune up on a 2011 dodge grand caravan with 175k with sludge build up from original owner doing oil changes every 8k-10k miles. Ive used other brands like seafoam in the past but that come nowhere close to motor purr. Got to thank Dalton of PBG YT for the discount code.

After watching PBG and others use this project repeatedly I'd figure I'd give it a try on my 1998 jeep with 214000 and my 2000 k3500 with 180000

I used the fuel injection cleaner and tune up in the crankcase on each followed the easy instructions have noticed that both idle and run better as stated by motor purr and the others will definitely continue to utilize it as outlined by motor purr

I got the tune up kit for my 94 explorer. It had been sitting almost ten years and when I got it going again the MAF sensor went out and made it run super rich and I limped it home. With that replaced I gave it the tune up to give it a good clean and now it runs better than ever!

This is my second time buying these products, and bought one of them for a friend. My cars GDI and this stuff WORKS! Over 200k miles and still going strong.
