Year Round Maintenance Schedule

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 improve fuel economy up to 8%.


If temperatures are below 30°F, add Diesel Fuel Supplement +Cetane Boost for winter operability. This Arctic Formula will prevent fuel gelling and protect against fuel-filter icing.

In a winter emergency

Use Diesel 911 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.

If microbial contamination is present

Treat with Bio Kleen Diesel Fuel Biocide to kill the microbes and Clear-Diesel Fuel & Tank Cleaner to remove the residual water and contaminants.
