Petrol engine mixed with diesel.As a result of the petrol being mixed with diesel fuel, the car will certainly stall, provided that the diesel fuel mixed with the petrol is in large volumes, because diesel fuel is a type of low explosive so that the spark plug cannot burn gasoline, especially if its character is low compression.However, this will be different if diesel fuel is mixed in a small volume, this will result in a sound in the engine or daily workshop language tickling.

Petrol mixed with diesel fuel Petrol mixes with diesel because the flash points of diesel and petrol are different. This condition makes the spark plug that should be able to burn become unburnable.Diesel is non-volatile and does not mix well with the air, once injected into the combustion chamber. Hence the spark from the spark plug does not cause combustion.So at the end of the compression stroke, the diesel still doesn’t ignite. The injected diesel is no longer in the form of mist but liquefies, then sticks to the surface of the piston, which ultimately makes the engine not start.The characteristics of diesel fuel can evaporate at 149 degrees Celsius. That’s why Diesel engines have high compression to create pressurised air, and high temperatures so that combustion occurs.Petrol can evaporate at 40 degrees Celsius. In other words, without much compression after being atomised in the engine room, petrol can burn immediately.
but for the safety of your car engine if this happens then the most appropriate step isIf this happens, the right step is to immediately drain the diesel that enters the petrol tank immediately.therefore pay careful attention when you want to refuel your vehicle with the right type
