I work from home so I don't drive that often.
I might drive once or twice per week to go into town that is 22 miles one way or go drive 11 miles to a friends house every few weeks or so.
I can get by usually filling up my car once per month but sometimes I'll fill up sooner if the gas tank is getting near 1/2 tank.
I always want to make sure I have gasoline in my car in case of an emergency though.
Because there can be times that gasoline may not be available during bad weather or emergencies and I may need to evacuate so it's best to keep the cars gas tank full.
