What are the effects of adding a small amount of gasoline to a diesel car?
2 Answers
If a diesel car has only added a small amount of gasoline, it can still be driven, but the power may decrease or the engine may experience shaking. Below is relevant information about engine oil: 1. Grade introduction: S indicates suitability for gasoline engines, with N being the highest grade for gasoline engine oil. C indicates suitability for diesel engines, with F being the highest grade for diesel engine oil. 2. Oil introduction: Engine oil, also known as engine lubricant (English name: Engine-oil), has a density of approximately 0.91×10³ (kg/m³). It serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption for the engine. It is hailed as the 'blood' of the car. Engine oil consists of two parts: base oil and additives. The base oil is the main component of lubricating oil, determining its basic properties, while additives can compensate for and improve the shortcomings of the base oil's performance, granting it certain new properties, making it an important component of lubricating oil.
Last time I refueled, I accidentally added some gasoline to my diesel pickup truck, and the result was quite a scene. The car struggled to start, panting like an old ox, shaking violently, with no power when driving, and emitting puffs of white smoke. Scared, I immediately pulled over to check the reason—turns out gasoline and diesel don’t mix. Gasoline’s high volatility interferes with the diesel engine’s compression ignition process and can wash away the oil’s lubricity, damaging the high-pressure pump and injectors. I quickly called a tow truck to take it to the shop. The mechanic inspected it and spent several hundred dollars cleaning the entire fuel system, warning that driving it further could have destroyed the engine. This taught me a lesson: always check the fuel pump color before refueling—don’t cut corners and make mistakes. Developing a habit of setting a phone alarm reminder can also prevent such mishaps.
