However, diesel is heavier and oilier than the gasoline so, when you pour the gas engine with diesel, the injectors feed the engine with loads of diesel as it sank inside the engine.

Moreover, forcing the engine to ignite might result in the burning of some parts and even the worst like fire catching. In addition, severe timing and cylinder issue might also occur.

So, never try to put diesel in gas engine as they both serve the different functioning of the engine and have different properties.

2. Signs of Diesel in Petrol

2. Which Engine can Bear More?

Diesel engines are normally stronger than the petrol engine but, when the petrol gets in contact with the diesel engine, it acts as a thinner, which automatically dries out the engine. This results in the fuel and the engine to wear down through friction. After facing this situation your engine might never work or the damaged parts need to be changed. The chances for big problems are high. Therefore, taking the maintenance tips from the experts is essential.

In this situation, where the diesel engine has no lubrication in it, trying to start the engine can make some additional damages due to pre-explosion. Diesel requires high combustion to ignite, as the petrol is more volatile, the too much pressure inside the engine makes the petrol to combust prematurely. This, as a result, forces the pistons to go out of their natural order. This type of condition might be hazardous as many components inside the engine are blocked.

All the above guidelines regarding the damage of pouring the diesel in gas engine, signs of diesel in petrol, and of course, the worst results of filling petrol in the diesel engine, will help you find the best car for you with a compatible engine.
