A cleaner diesel engine is a better-running diesel engine. Diesel Purge contains powerful cleaning agents that unclog injectors to improve starting, idling, fuel economy and acceleration. It also reducing smoke and other pollutants, so it's an excellent way to prepare for emission checks.
Diesel Purge isn't an additive, it's a unique formula that's designed to be run directly through the fuel system to remove corrosion and build-up within the system. Using it is an easy project for the do-it-yourself mechanic, but you can also have the work done by your dealer.
