Well, the intellectual elites that populate the great city of Kalamazoo saw it fit to line up around the block in their idling cars for gasoline that is $0.20/gallon less. 15 gallon tank equates to a total of $3 total savings, smh
No one does the math on this shit anymore. I have a 10 gal tank and get 40 mpg. There is a BP right next to my place that is 7 cents a gal more expensive than the gas stations 5 miles down the road.
To drive those ten miles, it costs me one dollar (assuming $4/gal gas.) Although I'm paying an extra 70 cents to fill up, I'm also not spending $1 in gas to drive there and back. Not to mention time.
Now people who wouldn't stop and pick up a quarter on the street will sit in a parking lot or road idling for 10-30 min waiting for a pump so they can save 10 cents a gallon from the station across the street. That's $1 total for a ten gallon tank, $1.50 for 15. It's even more ridiculous to stress over minute price differences when you consider gas is $4 a gallon now. At least when it was $1 a gallon, you were saving 10% over your overall cost. At $4 a gallon that percentage savings is minute.
I would go to that BP every time I needed to fill up, except for one factor I didn't mention. They carry E85 gas which burns shitty in my Civic, it cuts my gas milage down 10% overall. In my case, it's worth the extra dollar in fuel to drive up and get real gas that burns better and more efficiently in my engine.
