Can my unleaded engine run biodiesel fuel?

Question

I'm really interested in biodiesel fuel. I have an old ford explorer that runs on unleaded gas. Is there a kit I can buy to convert my engine to biodeisel fuel? The only kits I've seen convert diesel engines but not unleaded.

Answer 1

Running an unleaded petrol car on diesel is never a good idea

You may have time to start the car and get off the petrol station before it cuts out and refuses to start again

Answer 2

No, no more than it could run on diesel.  You would probably have better luck with alcohol.

Answer 3

NO!

Answer 4

No.  You will need a diesel engine and a fuel system that can withstand the solvent properties of biodiesel.

Answer 5

no

Answer 6

I'll third no that.

Generally it takes alot sturdier engine case/block to survive diesel combustion

Answer 7

Absolutely not. Diesel fuel is ignited by compression while gasoline fuel is ignited by spark. The space between the pistons and the top of the engine is much smaller on a diesel since it must compress the fuel to the point that it spontaneously combusts without any other source of combustion. A gasoline based engine also compresses the fuel but not as much as a diesel engine. A combination of the compressed fuel and a spark provided by a spark plug causes the fuel to explode and drive the piston downward.  Putting diesel fuel in a gas engine will only gum up the engine causing it to stall but will not generally destroy it.  Putting gasoline in a diesel engine will nearly always destroy it.
