If any of the above is true, why don't people, today, put gasoline into their diesel engines, considering the higher cost of diesel fuel?


I own a diesel F-250 and wouldn't dare do that. I previously, years ago, owned a Mercedes 300-D and the manual actually stated that - during cold weather - (I think it was so qualified) one could mix UP TO 30% gasoline with the diesel fuel. I suspect this was to help prevent the diesel fuel from congealing.

I have heard stories, unverified, that a diesel will "run away" on gasoline and over rev the engine, possibly disassembling itself, internally if not externally. A diesel operates at much higher pressures than a gasoline engine. The gasoline is far more explosive than diesel fuel. The diesel uses no spark plug to ignite the fuel. Instead it uses pressure to explode the fuel.

A web search of diesel engine might give much more detail and better advice. I'm also sure others will explain this much better. Just DON'T TRY IT, unless you can afford to replace the engine! :-)
