Milk In A Gas Tank: What REALLY Happens?! (Explained)

Milk in a gas tank will damage the car’s engine system. It is because milk is heavier than gasoline, so that it will sink in the bottom of your gas tank. 

So what will happen if you put milk in a gas tank? First, if the milk is already inside your gas tank, it will sink; now, the milk in the gas tank will get picked up by the fuel pump and sent to the engine. 

As soon as the milk reaches your engine injectors, your car’s engine will die. It is because milk will create curd, which will stick and clog the passageway of your car’s engine.

Long Term Effects

If you let the milk sit in your gas tank even though you already know that it’s inside, your car will get damaged permanently.

However, if you want to prank someone by putting milk inside their car gas tank, you make their lives miserable.
