Concentrated, detergent-based fuel additive cleans injectors, carburetors, valves and combustion chamber deposits with a concentrated blend of the most powerful high-temp and low-temp detergents available, 15 Ounce (4 Pack)
The fuel system cleaner seems to be working well, but I was disappointed with the delivery time. It took longer than expected to arrive. The cleaner is effective, though, and I could feel the improvement after just one use!

Great value in a 4-pack!
I love that this cleaner comes in a 4-pack! The Red Line system cleaner works wonders for my car, making it run like new again. It's easy to use, and I can just pour it in with my fuel. Highly recommend it for anyone looking to maintain their vehicle!

A noticeable difference in performance!
I bought the Red Line Complete Fuel System Cleaner for my older car, and I’m really impressed with the results. After using the 15-ounce bottle, the engine runs smoother, and I even noticed better gas mileage. Definitely worth the investment!

Not sure about the hype
I’ve used the Red Line fuel cleaner a couple of times, and while it does seem to clean the engine, I didn’t notice a huge change in performance. Maybe it takes more than just one 15-ounce bottle to see significant results. I’m on the fence about repurchasing.

Arrived damaged and messy
Unfortunately, one of the bottles in the 4-pack was damaged on arrival, which made quite a mess. The product itself seems good when used, but I was really frustrated with the shipping issues. I hope I can get a replacement!
