1. Engine damage:
* Fuel system clogging: Oil doesn't mix with gasoline. It will separate and clog the fuel lines, fuel filter, and injectors. This can lead to a restricted fuel flow, poor engine performance, and even engine stalling.
* Engine damage: If oil reaches the engine cylinders, it can contaminate the combustion process, leading to:
* Premature wear and tear: The oil can coat the cylinder walls, leading to increased friction and accelerated wear.
* Reduced engine power: The oil can prevent the spark plugs from igniting the fuel properly, causing misfires and reduced power.
* Engine seizing: In extreme cases, the oil can cause the pistons to seize in the cylinders, requiring a complete engine rebuild or replacement.
2. Other issues:
* Fuel pump damage: The oil can damage the fuel pump by clogging its filter or even causing it to seize.
* Emissions problems: The oil can affect the catalytic converter, leading to reduced efficiency and increased emissions.
* Costly repairs: Cleaning the fuel system and repairing any damage to the engine, fuel pump, or other components can be extremely expensive.
What to do if you accidentally put oil in your gas tank:
* Stop driving immediately.
* Do not start the engine.
* Contact a professional mechanic. They can assess the damage and advise on the best course of action.
Remember:
* Prevention is key. Always double-check your fluids before adding anything to your car.
* If you notice any signs of engine problems after adding oil to your gas tank, seek professional help immediately.
