I have never turned my vehicle off while pumping gas in my life and have yet to have an issue. Especially coming from a Northern state where it gets pretty cold you see a lot of people doing the same thing. What is the potential risk or is it all just a myth?
It’s bad for the Emissions system. When you open the gas cap while the car is running you can cause the ECM to think there is a leak in the Vacuum System. Don’t be lazy.
Just turn it off.
