What to Do If a Gasoline Car is Filled with Diesel?
1 Answers
If a gasoline car is filled with diesel, to avoid engine damage, it is best to drain all the fuel from the tank, clean it thoroughly, and then refill with the appropriate oil for the vehicle. Here is some relevant information: 1. Studies have shown that if the proportion of diesel added to gasoline does not exceed 5%, it generally does not cause significant damage to the engine. However, as the proportion of diesel increases, knocking and stalling may occur quickly, and in severe cases, it can lead to cylinder scoring. 2. The working conditions of gasoline engines differ from those of diesel engines. Gasoline has a lower ignition point, and gasoline cars typically ignite the air-fuel mixture via spark plugs, with lower cylinder pressure. Diesel cars, on the other hand, compress diesel fuel through a fuel injection pump to produce high-pressure diesel, which is then injected into the cylinder via the fuel injector, resulting in higher cylinder pressure, rougher operation, and larger clearance gaps. Therefore, the requirements for oil differ between gasoline and diesel engines. Gasoline engines require thinner oil with better fluidity, while diesel engines operate under higher pressure and harsher conditions, producing more carbon deposits, thus requiring oil with stronger cleaning capabilities, larger clearances, and thicker viscosity. Hence, gasoline cars should not use diesel engine oil.
