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!
The only time it would be an issue is if your evap system decides to check the integrity of the system at the same time you are refueling. It pulls the fuel tank down to vacuum and watches to see if the system bleeds back to atmospheric pressure. If you have the gas cap off, it cant pull vacuum and would set a large leak evap code. You could just clear the code with a code reader and move about your day. But the likelihood that it does this at the same time you are refueling would be extremely low in the first place.
