Start with Diesel Kleen plus Cetane Boost. Protect the life of your injectors, lubricate the injection system, smooth rough running engines and restore lost power and fuel economy with this year-round performance improver.

And Power Service knows that fuel and tank hygiene is just as critical to your diesel’s performance and longevity. Use quarterly to remove water and slime from your fuel system. Got equipment or fuel that sits for extended periods of time? Clear-Diesel will help with that too, so that your fuel is fresh when you need it.
