Scotty said: “I’m gonna tell you why you should never fill your tank all the way up to the top when you’re at the pump.
“And it isn’t just because you don’t want to make a mess and get gasoline all over the place.”
The short clip then cuts to a view of the opening of a car’s petrol tank.
Scotty explained that there are two holes on the inside of the petrol cap.
He said: “If you overfill your tank, you put petrol in the Evap – Evaporative Emission Control System – canister.
It is used to prevent petrol vapours from escaping into the atmosphere from the fuel tank and fuel system.
The expert warned that it can cost hundreds of pounds to replace.
Scotty advised that when your filling up and the pump clicks off, stop filling your tank.
