It will burn just as good as brand new oil, lol, it just dosnt lubricate as well any more. If you have an oil fired furnace it can be modified to burn used motor oil. I know of some shops who have them & use the oil for heat in winter.

 

Aww, Wikipedia has failed me! Well there you have it, it does burn.

 

no. Only vapors can.

 

same as gas.

liquid gas doesnt burn, vapors do

 

If ya want to get technical yes. How about we pour some oil over you & ignite the vapors. Just remember, the searing pain isnt from the oil its self burning, its from the vapors.
Wax dosnt burn either, its the vapors.
Actually if you want to get real technical nothing will burn w/o oxygen. There are metals like magnesium & chemicals that will burn in water or outer space but that is because thru a chemical reaction that the heat produces creates its own oxygen.

 

My pals and I pour our oil over a stack of wood to helpignite our bonfires.... gets rid of it pretty quick and we get to feel like we are doing our fair share to harm the environment with the black smoke it gives off for a couple of minutes!!

 

going by every action movie I've ever seen, itwill be AWESOME! lol
