I recently decided to test Redex Diesel Fuel System Cleaner after hearing good things about it from other drivers. After a few uses, my engine feels smoother, and the fuel economy has slightly improved. It also seems to reduce the rough idle I used to get on cold mornings. What I like most is how easy it is to pour into the tank — no mess or complicated steps. Some people claim Redex Diesel Fuel System Cleaner helps extend injector life, and I can see why. It’s a small investment that keeps the fuel system running cleaner for longer.
