Power Service Diesel Kleen + Cetane Boost, 6/80 ounce case, is a technologically advanced diesel engine performance improver that cleans injectors, boosts cetane and lubricates fuel injection components. This Max HP Formula restores lost power, smooths rough-running engines and improves fuel economy up to 8%. This fuel supplement can be used year-around, but it is not a diesel fuel winterizer or antigel. When winter temperatures drop below + 30F use Power Service Diesel Fuel Supplement + Cetane Boost (in the white bottle) to provide maximum winter protection for your diesel engine. It also has the following benefits:

• 1, 80 oz. bottle treats 250 gallons of Diesel Fuel
• Cleans dirty injectors and prevents injector sticking in all engines, including High Pressure Common Rail (HPCR) systems
• Boosts cetane up to 6 numbers - engines run smoother with less power lag and faster cold starts
• Boosts power - reduces need for downshifting during high-load conditions
• Improves fuel economy up to 8% - fuel savings exceed cost of additive
• Contains Slickdiesel Lubricator for maximum fuel lubrication - protects pumps and injectors from accelerated wear
• Stabilizes stored fuel
• Prevents thermal/oxidative breakdown of diesel fuel - protects against sludge formation that plugs fuel-filters and injectors
• Effective in all diesel fuels, including Ultra Low Sulfur Diesel (ULSD), biodiesel and biodiesel blends
