Year-Round Maintenance Schedule
To ensure peak performance of your diesel, Power Service recommends this Year-Round Maintenance Schedule. Check out our video for more information.
Every time you fill up
If temperatures are above 30°F., add Diesel Kleen +Cetane Boost (silver bottle) to clean injectors, boost power, lubricate pumps and injectors and restore lost power and fuel economy.
If temperatures are below 30°F., add Diesel Fuel Supplement +Cetane Boost (white bottle) for winter operability. It prevents fuel gelling and protects against fuel-filter icing.
In a winter emergency
Use Diesel 9•1•1 to reliquify gelled fuel and de-ice frozen fuel-filters if your vehicle will not start or gain power in cold weather.
At least quarterly or as needed
Treat with Clear-Diesel Fuel & Tank Cleaner to remove water, disperse contaminants and ensure fuel is stabilized for long-term storage.
