I'm going to leave the car in a garage for 2 weeks while I head off on a trip. Does it matter if the fuel tank is full or close to empty or should it be half-full during that time period? How much gasoline should there be in a tank when you leave a car alone? Or it doesn't matter how much fuel will be in the tank?

If I leave a vehicle sitting for any length of time, I always fill up the tank right before I park it. For two weeks, I wouldn't sweat it this time of the year. In Alaska, in the winter, I would fill it due to condensation, even if it was only sitting two weeks. But only if it was outside or in an unheated garage. In a heated garage, so sweat.

I wouldn't worry about it for just two weeks but if you are going to store any gasoline for a longer length of time whether it's a lawnmower, gas can or your car it should be full. In addition to the condensation issue already mentioned the air will also react with gasoline.

Two weeks? I leave my car sitting in a airport parking lot for a few months with around a half tank of gas. When I fly back in, I stop and fill it up and within a week get a oil change. fwiw it's a Toyota/Lexus vehicle.

2 weeks is nothing. Just park the car with whatever gas is in it, and come back and start it up and continue on.




My current garage queen has gas in the tank from 2 years ago and it still starts up and runs on it without issue.

I leave my cars without being driven for up to a month at a time in some cases. I wouldn't even consider it a factor (IMO).

Not an issue for two weeks. More importantly, when you get back, check the air in the tires.

We always fill our tanks before we go on vacation.
Just a personal preference, with all the hassle of flying, delays and whatnot; we don't want an added gas station stop.
