How often should I use Power Service diesel additives?

Our recommended Year-Round Maintenance Schedule is:

Every time you fill up:

• If temperatures are above 30°F, add Diesel Kleen +Cetane Boost (silver bottle) for maximum performance. This Max HP Formula is loaded with cetane, detergent and lubricity improver to provide peak diesel performance.
• If temperatures are below 30°F, add Diesel Fuel Supplement +Cetane Boost (white bottle) for winter operability. This Arctic Formula will prevent fuel gelling and protect against fuel-filter icing.

(Use our Seasonal Tip: White for winter, silver for summer!)

In a winter emergency:

• Use Diesel 911 to reliquefy 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:

• Add Clear-Diesel Fuel & Tank Cleaner to remove water, disperse contaminants and stabilize fuel 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 residual water and contaminants
