The wax in cold winter times solidifies and clogs supply tubes.<br />See my own findings about as I been in Petro Industry all my life in Arctic as well seeing engines suffer:<br />Jet Fuel & Diesel Fuel?<br />Jet fuel of types A and A-1 is composed of mostly kerosene, and Jet B is a naptha-kerosene mix. Diesel fuel is approx. 75 percent kerosene, with added lubricants and a low-sulfur content.<br />Diesel has lubricant additives to promote healthy engine function–using kerosene or Jet-A fuels in a diesel engine may cause damage due to its lower levels of lubricants.<br />Engine Use - Conclusions<br />While many attest to using 50-50 ratios of jet/diesel in diesel engines, this will cause the engine to run hotter and have a lower mpg rating. It will also void many warranties by the manufacturer. Jet-A is more similar to Diesel #1, which is lighter than Diesel #2 (automotive diesel), and so is not a perfect substitute, but in emergency situations is a potential fuel source. Jet-A usage will not cause instant physical damage but long-term wear will increase due to lack of lubrication, different burn temperatures and energy output.<br />The viscosity specifications for the two fuels is different. Jet-A and Diesel #1 tend towards lower viscosity than Diesel #2. Lower lubricity is likely as the viscosity decreases. This may not cause catastrophic instant damage, but it may cause long-term wear of pumps, injectors, etc.<br /><br />To overcome the problem when Jet fuel A is only available Mix with two stroke engine oil.<br />Standard Treatment Rate: 1 to 512 minimum (.25oz per gallon of fuel)<br />Recommended Rate (cold weather): 1 to 256 (.5oz per gallon of fuel)<br />1 quart treats 64 - 128 gallons of diesel fuelThu, 05 Sep 2024 08:13:00 GMTsimoncurrin
