No great surprise, the crap diesel we get from Pakistan which is full of parrafin and other crud, beginning to gel now that winter is upon us. Anyone aware of a site that discussess non commercial additives (ie gas, kero, or JP4 -we got lots of each) that can be added to make the diesel flow better. I saw one thread here that said 1 qt kero to six gallons, but a website would be really helpful. Apparently Mercedes recommends up to 30% gas in really cold situations.
 
If you post on www.agriculture.com a bunch of farmers will be jumping opn this with both feet, and a load of suggestions.

Gelling is primarily due to water contamination. You may also have microbial contamination witch is an equine of a different hue.
Diesel is a lot like mayonaze, and 2 problems occurr when Diesel is pumped, or moved. Diesel incorporates both air & water, and it takes about 12 hours for both to settle out.
Most problems caused by gelling are alleviated by fueling the machine at the beginning of the day rather than filling at night, and letting the machine sit overnight.
Observe aircraft fueling operations, they fill the truck from the tankfarm, and let the truck sit for hours to let the water and disolved parafin settle. Then they drain 5 gallons from the bottom of the tank, before fueling an aircraft. Aircraft do not sit around after fueling, they takeoff.
Gelling will rarely occurr on a running diesel, because the fuel that doesn't go to the injectors is circulated back to the tank.
Using gasoline and kero or jp as an antigell is a last resort. Different engines will tolerate different levels of dilution, so it would be best to check with the engine manufacturer.
Are you filtering your diesel before it goes into the machine? Filters will remove most of the excess parafin and most of the water if used properly. Also, a lot of problems can be eliminated by raising the pump pickup up in the bulk tank.
 
It is the parrafin that is clogging the filters, hence the requirement for a de geller, be it kero or something else. The filters are being changed almost everyday on our generators, the armoured vehicles fortunately were designed for operation in cold Canadian climates, thus they have heaters in the fuel tanks. What is happening is that the generators are stopping due to fuel starvation in the middle of the night because the filters are clogged with all the junk that is in this low quality fuel.
 
Jumper, is there a CB outfit around there?
Are the gensets air cooled or water cooled? If water cooled, it's simple enough to put fuel heaters onto the system.
Also, are you fueling from cans or a tanker?
