Can you mix diesel fuel with oil?
Yes, but don't put the two chemicals in the actual engine. It might actually combust and explode the vehicle.
You can't use it as oil in an engine. The engine will fail.
You can't use it a fuel, you will damage the injection system and engine.
I guess you could mix it for use in a waste oil furnace.
Diesel fuel is often referred to as "diesel oil" or "heavy oil". Do not confuse this with "engine oil for a diesel engine" which means "lubricating oil specially formulated for use in diesel engines". My first Ford Fiesta diesel's tax disc said - "Fuel - Heavy Oil". They've now realised that this term is anachronistic, and my latest tax disc reads "Fuel - Diesel". To be pedantic - Diesel fuel is an oil - Petrol…
thses 2 can be mixed, but to what reason do you want to mix them. if you are going to mix these and use them in a vehicle you are going to blow smoke from burning oil in deisel, or trash engine from using diluted oil in engine go to www.bluegrassfuel.net , they have all the info one would need to use motor oil as fuel.
You can try using corn oil for biodiesel. Corn oil is used for cooking and used cooking oil is used for diesel fuel. Actually, the process of cooking with oil performs the same process on the corn oil as crackling does in an oil refinery. Thus, it would be possible to take corn oil and mix it with petroleum in a refinery and create diesel fuel.
