Diesel fuel for oil furnace?
My neighbor totalled his pickup truck, and is going to junk it. The truck has almost a full tank of diesel (about 28 gallons.) He asked me if I want the diesel (free!) for my #2 oil fired furnace. (He has gas heat.) He claims #2 oil and diesel are virtually the same, and I have always believed that, too. But I wanted to get other advice first!
Will diesel wreck my oil burner??
