Diesel and kerosene are the same product. Its kerosene is dry.. No lube in it. Wont harm the pump if you lube it with oil or atf but add something to lube the pump. Kerosene comes off the fractionation tower a little higher up than diesel so its lighter and cleaner. Gasolene is higher up than kero and white gas is even higher up...
Not exactly . Kero is close to number 1 diesel, that is always blended for winter use with number 2, but never used straight because it will kill the fuel system, and even number 1 diesel has some added lubrication, although not as much since that is one of the things that leads to gelling straight kero is WAY too dry to run in diesel systems without added lubrication. They'll burn it ( heck, they'll burn just about anything (, but you need to throw some kind of oil in with it or you are begging for trouble
