Best Injector Cleaner

For over 6,000 miles I battled various mis-fire codes on my '02 Camry. I had finally determined that it must be the fuel injectors. I ordered new injectors and, while I waited, read a review on line that said I should try an injector cleaner. I've used a variety of brands over the years without much success, but decided to give it a shot. I bought a bottle of Regane High Mileage Fuel System Cleaner, still unconvinced that it would work. A quarter of a tank later, my check engine light went off and my car is running smooth. I can't recommend this product highly enough.

'94 Mercury Grand Marquis

Pleasantly surprised by the effectiveness of this product. Put this in my mother's aging Mercury with 157k on the clock because it developed a light ping during summer months under mild acceleration loads. RxP has been my preferred product to blow out carbon, but it didn't work on this engine. One treatment of Gumout High-Mileage eliminated pinging under most conditions. When it does ping it is much more subdued than before. Very impressive. Five stars.

Better Gas Mileage

I use Gumout Regane pretty much after every Jiffy Lube oil change, it keeps my Jeep running tip top. Unlike paying $100 for a fuel system cleaning by the pros, I just pour this into my tank and it keeps the fuel system clean. I first tried a few years ago when my car was hesitating. What I found was that it clean up the fuel injectors but also improved my gas milage...now its a must.

Best fuel system cleaner

I've been using Regane for years , because it has the best combination of ingredients to get the job done that it takes several other brands combined to do.
