Fuel Game

I have never bothered trying to play the fuel game however now that there are only three spots to choose from and they are always the same price relative to each other, I have been paying attention to servos closer to Geelong.  I suspected that the fuel would be a bit cheaper in Geelong and on first look it was 10 c cheaper. However yesterday it was the other way around with Drysdale 10 c cheaper than Geelong.  Go figure. So it pays for the coffee and cake ($6.00) when a full tank is filled at the right time.
