How long can I leave my Mazda6 car engine without starting? I'm going on a trip for 5 days.
Probably a year or 2 ... I know someone that left theirs for 5 years and needed a jump for the battery ,,, it started right up
If you were going to be gone for 6 months or more, I would recommend using a fuel stabilizer in a full tank of fresh fuel, a battery tender and jacking the car up on all 4 corners so the tires didn't touch the ground. Since you are going to be gone for only 5 days, don't worry about it.
