Kerosene is blended with diesel fuel to improve winter fuel operation. Kerosene blended diesel fuel is mixed with ratios from 80 parts diesel, 20 parts kerosene to a maximum 50 part to 50 part mixture depending on the severity of cold weather. While kerosene has an ignition quality similar to #2 diesel fuel, it is too thin to work well as an engine fuel alone and has poor lubricating capabilities inherent in heavier #2 diesel. Kerosene can be mixed with diesel fuel by the truck owner or operator.
Looks to me like you should sell it - not use it - at least not in your diesel engines.
