Can kerosene be used in a diesel truck for fuel?

No, kerosene should not be used in a diesel truck. While both are petroleum-based fuels, they have significantly different chemical compositions and cetane numbers (a measure of ignition quality). Kerosene has a much lower cetane number than diesel fuel, meaning it ignites much less readily in a diesel engine's compression-ignition system. Using kerosene will likely result in:

* Poor or no combustion: The engine may struggle to start, run poorly, or not run at all.

* Damage to the fuel system: Kerosene can damage fuel injectors and other components due to its different properties.

* Reduced engine performance: Even if it runs, the engine will likely produce significantly less power and efficiency.

In short, using kerosene in a diesel truck is a bad idea and could cause significant damage. Stick to diesel fuel.
