 I've never had a feeling either way. I certainly don't recommend putting it in near empty, okay? You want your fuel pump, if it is in the tank, and again, some of the older cars it's not, but if your fuel pump is in the tank, you want your fuel pump sitting in fuel. So you don't want your car stored empty. But it doesn't have to be full either. Half a tank or more is probably fine. Okay.
