coming up on "cheap" gas is overrated
let's say you came across a gas station that was 20 cents cheaper per gallon... most cars are like 15 gallons, maybe 20 gallons, so you'd be saving less than $2.50 if you were on empty and filled the entire tank; that's about 10 bucks a month
I mean, it's cool if you just so happened to come across that gas station because it was on the way or whatever, but I've seen people go out of their way to go to a gas station that was like 10 cents cheaper per gallon and they only filled up half a tank
