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.

Not very impressed
I’m switching to a different additive because I’ve gelled up 2 years in a row now. 2 different vehicles, 2 different fuel stations, and I get left stranded. Winter blend at Casey’s 1 year with this additive, and Cenex 50/50 this year, not even below 0, and my pickup didn’t make it very far before it lost fuel pressure. New AirDog lift pump and new high-pressure pump, as well as new injectors, so I’m fairly certain it’s not a fuel system issue, but more likely the fuel itself. I’m adding a fuel heater and switching to a different additive because it’s frustrating being unable to trust my diesel pickup in these cooler winter temps.

Maybe Early to Tell
I am still on the first tank of fuel so it may be too early to tell how well this fuel additive works. It also hasn't gotten really cold yet but there does seem to be a reduction in cold start clatter which I was hoping for. My order was quickly filled and arrived promptly. If I had anything that I might change it would be having the option to buy a case, not looking for a 'case discount' but I could have easily ordered a few more or less bottles and had the product arrive as packaged by the manufacturer rather than a number of bottles in a plastic bag, in a loose-fitting box. It would have been easier to keep them in my truck that way as well. I do have to say that the bottles all arrived in fine condition and nothing leaked, the case idea just occurred to me as I was unpacking the bottle and thinking about having 10 of them sliding around in my truck.

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.

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
