Oil generally burns at a similar temperature to gas, but hotter than coal. The burning temperature can also depend on the specific type of oil or gas being used.
Fossil fuels (coal, oil and natural gas).
2 Cycle oil does not "burn" so that it leave behind a oil film when the gas burns off. you may see the words "ash-less" on some brands of 2 cycle oil. 4 cycle oil will burn and turn sticky, gumming up your engine.
