What happens when you pour brake fluid in the gas tank?

Brake fluid is typically not compatible with gasoline and can cause damage to the fuel system and the engine. Here is what can happen when you pour brake fluid in the gas tank:

1. Reduced Engine Performance: Brake fluid can alter the fuel mixture and reduce the engine's efficiency, leading to poor performance, sluggish acceleration, or engine misfires.

2. Corrosion and Damage to Fuel System Components: Brake fluid can have corrosive properties and can damage components such as fuel lines, fuel filters, and injectors. This can lead to fuel leaks and other issues.

3. Clogging of Injectors: Brake fluid can clog fuel injectors, hindering proper fuel flow to the engine. This can cause engine performance problems, hesitation, and rough idling.

4. Damage to Fuel Pump: Brake fluid can also damage the fuel pump, which is responsible for delivering fuel to the engine. This can lead to fuel starvation, engine stalling, and difficulty starting.

5. Hydrolock: In severe cases, if enough brake fluid enters the cylinders and creates a hydraulic lock, it can prevent the pistons from moving freely. This condition is known as hydrolock and can cause significant engine damage.

It's important to avoid mixing brake fluid with gasoline and take caution when handling these substances. If you accidentally pour brake fluid in the gas tank, it is recommended to seek professional assistance from an automotive mechanic to safely remove the contaminated fuel, flush the fuel system, and make necessary repairs to prevent further damage to your vehicle.
