As colder weather approaches you need to use fuel additives to prevent fuel jelling. Fuel additive should be added anytime the ambient temperature is below 32 degrees F. Power Service and Penray are popular manufactures of fuel additives and both companies have two different products available through Navistar and Idealease locations.

Power Service:

• The “Red Bottle” is Power Service 911 and is to be used only when the fuel in a unit has been jelled and NOT TO BE USED AS A PREVENTATIVE MEASURE TO KEEP FUEL FROM JELLING.
• Power Service Diesel Fuel Supplement + Cetane “White Bottle” is to be added to the fuel at each fill when the ambient temperature is < 32 degrees F.
• This is the additive you should use on a regular basis during the winter months.
