Using starter fluid on a diesel engine is generally discouraged. Diesel engines rely on compression for ignition, and starter fluid can cause pre-ignition or even damage the engine’s internal components. Instead, address the root cause of the starting issue by checking the glow plugs, fuel system, and battery health to ensure proper functioning.
