Immediately:
* Stop the engine immediately. Do not attempt to restart it. Continuing to run the engine will cause extensive damage.
* Do not attempt to start the engine again.
Next Steps:
* Call a professional roadside assistance service or a tow truck. They are best equipped to handle the situation. Trying to fix this yourself could worsen the problem.
* Contact a qualified mechanic specializing in diesel engines. They will need to drain the fuel tank completely, flush the fuel system, and potentially replace damaged components. This is not a DIY job.
* Document everything. Take pictures or videos of the situation. Keep records of all communication with roadside assistance, the mechanic, and any expenses incurred. This may be important for insurance purposes.
The Damage:
Gasoline in a diesel engine can cause:
* Damage to fuel injectors: Gasoline is less viscous than diesel and can damage the delicate fuel injectors.
* Damage to the fuel pump: The fuel pump may be unable to handle the gasoline.
* Damage to the engine's internal components: Gasoline burns differently than diesel, potentially causing damage to pistons, cylinders, and other parts.
* Catalytic converter damage: (If equipped) Gasoline combustion can damage the catalytic converter.
The cost of repairs can be substantial, potentially reaching thousands of dollars. Prevention is key; always double-check the fuel type before refueling.
