I have about 35 gallons of various viscosity motor and lube oil saved in one of those blue polycarbonate barrels. Some may know this: mixed motor oil, diesel fuel, gasoline and dissolved sponge-like packing peanuts makes for a very sticky and highly flammable liquid. A gallon inside a 5-gallon bin makes a handy "pot a'feu", nes't pa?" Hey Kids! Don't try this at home! You'll burn the neighborhood down!
