I bought a cheap little kerosene lantern at Wally Worl for $5 the other day. the gallon of kerosene they sell costs $10 so i thought I could just burn diesel in it instead. It is outside right now running but it's not throwing much light and is putting off pretty good black smoke and is turning the glass black as well. I have the wick just about 1/16" up but it still smokes. I assumed that since diesel and kerosene are very similar fuels I could substitute one for the other and save money, but the excessive smoke and lack of light may have me re-thinking this. Anyone else care to throw in some wisdom?
