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 for Kioti Tractors!!
We are a Kioti dealer in New England. All new tractors cannot use denature alcohol in them. It ruins the injectors. This has been a life saver for our customers on these cold winter days.

Questions and Answers

Fuel gelling problem at 30 below zero I was recently in temperatures of 30 below zero F. with my Dodge 3500 with 5.9L Cummins. I used one ounce of XDP polar formula per 30 gallons of fuel. My fuel line froze up and I had a heck of a time getting it running. What is the amount of XDP Polar needed in 30 gallons of fuel to prevent gelling at 30 below zero?
View Staff Answer 

Diesel fuel can begin to cloud around 32ºF and gelling can begin as high as 10ºF - 15ºF (depending on fuel quality and location). Gelling of your fuel is often referred to as the CFPP (Cold Filter Plugging Point). With just 1oz of our Polar-D additive in 8 gallons of fuel you can lower the CFPP by at least 10ºF. (Add prior to filling the fuel tank to assure proper mixing)\

*Keep in mind that our fuel additive is designed to help reduce the problems associated with diesel fuels in extreme temps and extend the temperature rang in which a vehicle can operate. (Fuel quality, location, and the temperature of the fuel prior to mixing can all make a difference on the additives reaction)

Can i use this product year round?
View Staff Answer 

The XDP Polar-D Winter Formula Diesel Fuel Additive can be used year-round, but better prevents fuel problems that are related to winter operations. The XDP Diesel Power Plus Fuel Additive is better suited as a year round formula. Click Here to view the XDP Diesel Power Plus Fuel Additive

What is the "shelf life" of a new bottle of XPD -D polar? On occasion I run up to MN in the winter and would like to keep in my truck. Will summer heat (Texas) decrease the efficiency of the product?
