1. Engine Damage: Diesel engines are designed to run on diesel fuel, which has different properties compared to gasoline. Mixing gas with diesel can cause damage to the engine's components, such as the fuel injectors, piston rings, and cylinder walls.
2. Reduced Performance: The engine may experience a loss of power and efficiency when running on mixed gas and diesel. This is because the combustion characteristics of gas and diesel are different, and the engine's fuel system and engine management system are tuned for diesel fuel.
3. Incomplete Combustion: Mixing gas with diesel can lead to incomplete combustion, resulting in increased emissions of unburned hydrocarbons and soot. This can cause the engine to run rough and produce excessive smoke.
4. Fuel System Issues: The fuel system may experience problems such as injector clogging or fuel filter blockage due to the presence of gasoline, which can affect the fuel flow and engine performance.
5. Engine Stalling: In some cases, the engine may stall or refuse to start if the proportion of gas in the mixture is too high.
6. Reduced Lubricity: Gasoline has lower lubricity compared to diesel, which can increase wear and tear on the engine components, especially the fuel injection system.
7. Emission Control System Issues: The emission control systems, such as the catalytic converter and particulate filter, may be affected by the presence of gasoline in the diesel fuel, potentially reducing their efficiency.
It is important to note that running a diesel engine on mixed gas and diesel is not recommended and can cause serious engine damage and performance issues. If you suspect that your diesel engine has been run on mixed fuel, it is advisable to have it inspected and serviced by a qualified mechanic as soon as possible.
