Either it will not run at all, or run very poorly. Either is likely to do severe damage to the engine.
The engine will knock.
It will stall the engine
after a while it would be irritating
Because petrol is a combustible substance. Water is inert.
Diesel, being a liquid, is non-compressible, and since a diesel engine needs to compress air for (adiabatic) ignition, it won't be able to compress it, so it will jam the engine. Unlike gasoline, it will take a long time for the diesel inside to evaporate, so the vehicle is stuck until you fix it. This can be remedied on most diesel engines by arduously loosening or removing the injectors and then draining by suction or by cranking the engine until enough is squirted out to allow the engine to turn over.
Have someone drain out the oil and replace the filter, now! Do not run the engine! This is not good for the engine!
Petrol will float on the surface of water, as petrol is less dense than water. So, it would be possible to set fire to a river, provided petrol is poured over the surface first!
If your husband poured barsleak in the crankcase, it probably stopped up the oil pickup screen. It is supposed to be poured in the radiator. The engine is probably ruined if you have driven it with the oil light on.
A conflict is like a 'fire'. Water puts out the fire. Petrol makes the fire stronger. Water or petrol poured on the fire(conflict )
you need to get petrol or it might be the engine or you need a new spark plug
Not very long because when sugar is poured into a petrol or gas tank it sits at the bottom of the tank and makes the engine run really badly and costs a lot to fix
I don't know if I should answer this, but antifreeze or regular engine oil would do the trick. But it won't happen right away it will take between 500- 1000 miles
