1. Stop immediately. Do not start the car. Driving it could cause significant damage.
2. Do not turn the ignition key. Avoid even trying to crank the engine.
3. Contact a roadside assistance service or a tow truck. Get your car towed to a qualified mechanic *immediately*. Do not attempt to drive the vehicle.
4. Inform the tow truck driver and the mechanic about the mistake. Clearly explain that you accidentally put ethanol fuel in a non-compatible vehicle. This is crucial information for them to properly assess the situation and take appropriate action.
Why is this so serious?
Ethanol blends higher than E10 (10% ethanol, 90% gasoline) can damage certain car components, especially those made of rubber and plastic parts in the fuel system. These parts may swell, crack, or dissolve when exposed to higher ethanol concentrations. This can lead to:
* Fuel leaks: Potentially dangerous.
* Engine damage: From malfunctioning fuel pumps, injectors, and other components.
* Expensive repairs: The cost to replace damaged fuel system components can be substantial.
Do NOT try to:
* Drive the car: This will almost certainly worsen the damage.
* Add gasoline to "dilute" the ethanol: This might not be enough to prevent damage and could complicate the repair process.
* Attempt any DIY fixes: This is beyond the capabilities of most individuals and could lead to further damage.
The best course of action is to get professional help as quickly as possible to minimize the extent of the damage.
