What if gasoline is used in a diesel engine?

Answer 1

Bad Things Will happenEither something expensive or something very expensive is going to happen. Since gasoline is designed to be resistant to self-ignition, gasoline in a diesel engine either won't ignite or will ignite at the wrong time. Some diesel engines run leaner than gasoline engines (meaning that the air-fuel mix has a higher proportion of air than a gasoline engine). That increases the chances that the gasoline won't ignite and that unburnt fuel will be sent into the hot exhaust system--where, ironically, it could ignite, leading to possible exhaust damage. Even if you avoid that disaster, you can expect to pay $500 to drain the fuel tank, clean out the fuel lines, and refill the tank with diesel. Some types of diesel engine use the diesel fuel as a lubricant for the fuel pump (remember, it's a fuel oil). Running gasoline through such a pump could lead to serious damage or failure, leading to a very expensive repair.

Hi,your diesel engine will go really quick for a little bit.

NOTHING MUCH WILL HAPPEN, the engine will not run or run so badly that you will have to investigate. drain out as much of the incorrect fuel as you can and refill with the correct fuel. If it is a diesel engine, use the primer pump to extract as much gas as possible. You can then top up with the correct fuel with as much as about a 5% mix, starting will take a little time but take it easy, once the engine is running smoothly again you can apply power, but take it easy for the first few miles. IGNORE THE NAYSAYERS, NO DAMAGE WILL BE DONE OVER A SHORT PERIOD. I HAVE DONE THIS ON NUMEROUS OCCASIONS - THOSE THAT SAY OTHERWISE ARE JUST TRYING TO FRIGHTEN YOUR MONEY OFF YOU - I HAVE HEARD THIS COSTING PEOPLE THOUSANDS - ALL UNNECESSARY!
