Before you heckle me - no I’m not stupid, and under normal circumstances I usually would turn the car off. In this particular instance, however, my car battery died because I was away for 6 weeks, and there’s not enough gas for me to take it on the highway and get to where I need to go tomorrow (after I try jumping the car). Since if i turn the engine off there’s a large likelihood that the car will die and won’t turn back on again, turning the car off while I fill my tank isn’t a very viable option. Can I get away with it one time, or will I ruin my engine or blow up my car?
If it makes a difference - 2020 Land Rover discover (sport). If that’s not viable, what are my other options for charging my car up enough with only <30 miles in the tank so that I’ll be able to also refuel my car without the battery going out?
Thanks!
It will throw a check engine light for a few weeks.
No it won’t
Depends on the vehicle, engine temp, and a few other factors, but yes theres a chance it will. If the car happens to run the vac/pressure test as you open the tank, then it will, but i would say, maybe 10% chance.
Unlikely with doing it for the duration of getting gas, but even if it does, it should clear itself within a couple of drive cycles once the computer is satisfied the issue is resolved.
