Penray Fuel Prep™ Diesel Fuel Conditioner is a year-round fuel treatment that combats sludge formation and disperses existing sludge in fuel tanks. Fuel Prep™ also conditions less stable diesel fuels by allowing them to burn cleaner and more completely, thus improving emissions and injector spray patterns to help extend diesel particulate regeneration cycles. Fuel Prep™ also reduces the accumulation of unburned carbon particles so engines stay cleaner. Regular use of this conditioner also reduces lube oil dilution and contamination.
