Diesel itself has some lubrication quality and it lubricates the precision parts in the fuel pump and delivery system while petrol goes the other way, thus the bad thing is the nature of the fuel. Now when driver miss-fuelled, his next question would be what do I do now?

Simply shut your engine off and call wrong fuel assistance as you need to remove this fuel out of the fuel tank now. If it gets into the fuel lines and injectors, it can cost you up to 1000gbp depending on your vehicle type.

Filling petrol in a diesel-powered car is far way dangerous than vice versa. As discussed earlier, petrol combust earlier and it also acts as an anti-lube agent while diesel itself works as a lubricant for precision parts. You can face misfires, bad cylinder lubrication and sudden drop in power on the go.

There would be no significant benefits to doing this.

In the hot weather and long driving, the high octane fuel can help by adjusting the engine timing and adding some longevity to the engine. However, the extra money should be spent somewhere else rather than on the fuel.
