Wrong Fuel In The Car?

First of all, if you’ve ended up pumping the wrong fuel in, no need to panic. A frustrated mind can get you and your car both in trouble by not taking the right decision and as a result, you might end up doing something which you weren’t supposed to.

Difference between diesel and gasoline combustion mechanism

Most people think that diesel and gasoline have no major difference and both work on the same mechanism. However, the real story is quite different. Diesel and gasoline combustion takes place quite differently.


Diesel, apart from powering up your engine, works as a lubricant as well. The diesel mill then compresses the diesel to ignite.

On the other hand, gasoline is only meant for combustion. It doesn’t have the tendency to lube the engine parts. Therefore, if you filled diesel in a gasoline car it won't start easily and problems like clogging may occur. Same happens when gasoline is pumped in a diesel car, which isn't capable of lubricating the engine. The situation will get worse due to increased friction in certain engine parts.

But as we’ve already told you, there is no need to worry. Accidents happen and it is not a major threat to your vehicle. Given that you follow the below-mentioned instructions carefully.
