Kerosine, or K1, is a middle distillate and has an end boiling point (~550*F) between gasoline (437*F) and diesel fuel (640*F). Essentially, kerosene is jet fuel (Jet A) and becasue it's nearly all straight-chain paraffin, it has no real octane number and will lower the octane rating of your fuel by roughly the volume amount you add to your tank. I've heard in the 1930s farmers would start their Model A trucks on gasoline and then fill them with kerosene to run the rest of the day (hauling vegetables and fruit from the Hudson Valley to New York City). But with an end point of ~550*F, it's doubtfull it will completely combust leading to oil dilution and washing of the cylinder walls and carbon buildup in the ring areas. Personally, I wouldn't put kerosene in my tank (but then, I don't use MMO either).
