Purchase XDP Polar-D for your vehicle today and get the winter blend your diesel engine needs. XDP Polar-D is formulated to prevent waxing and gelling while enhancing lubricity and cetane so starting your diesel engine in cold weather is easier. The result of a rigorous R&D period, this powerful fuel treatment increases overall fuel system performance in freezing weather conditions.  

XDP Polar-D is the perfect cold weather treatment that allows the use of number two diesel fuel year-round. Polar-D prevents common fuel problems related to cold climates, such as gelling and freeze-up. These issues are addressed by using wax modifiers that help prevent the formation of ice crystals, which prevents filter plugging. Polar-D contains special water-converting agents that address fuel system freeze up and prevent free or emulsified water from freezing. XDP Polar-D is enhanced with cetane to improve combustion and cold starting to help restore power and efficiency. 

The national Cetane number average is 45, so the added cetane means your diesel operates more efficiently. Fuels with a higher cetane number have shorter ignition delays which provides more time for the fuel combustion process to be completed. Higher speed (RPM) diesels operate more effectively with higher cetane number fuels.

Great product at a great price.
Just filled up my first tank while using XDP Polar D. I must say, so far, so good! Truck runs great and starts right up! Truck is not plugged into the block heater, and last night it was in the teens. Truck started right up!! XDP Polar D must be doing its job!! Was using Diesel 911 but am definitely going to be switching my diesel treatment to the XDP stuff. The guys over at XDP definitely know what they are doing!
soo the temp has been around -20 with a windchill of -45... no fuel bowl heater, no intake heater, everyone else is having problems with keeping their fuel from gelling.. well i run the XDP Polar D and i not once had a problem with Gelling! not in these temps! truck starts right up thanks to this additive! id recommend this to everyone! well worth it for a winter additive! truck starts up so much smoother in the cold! LOVE THE STUFF!

XDP Polar-D is a cold weather treatment that allows the use of number two diesel fuel year round. It prevents fuel problems related to winter operations, such as gelling and freeze up. The winter problems are addressed by using wax modifiers that prevent the formation of ice crystals, thus preventing filter plugging. It contains water-converting agents preventing free or emulsified water from freezing, and therefore addresses fuel system freeze up. XDP Polar-D is enhanced with cetane to improve cold starting capacity and to restore power levels found in good number two diesel fuel.

What is the lowest temperature to which your product will prevent gelling? Will it prevent the gelling of diesel fuel in our filter of our above ground 500 gallon tank while it is being dispensed?
View Staff Answer 
To lower the Cold Filter Plug Point (CFPP)
Diesel fuel can begin clouding and waxing at 32ºF and gelling (CFPP) between 10ºF - 15ºF depending on fuel quality
1 oz. added to 8 Gallons lowers CFPP by at least 10ºF
2 oz. added to 8 Gallons lowers CFPP by at least 20°F
Treating a 500 gallon tank would take 60 bottles to lower the CFPP by 20°F (Making your gelling point roughly (-5)ºF - (-10)ºF
