Just imagine that you have made money when you fill it one day and the next day it goes up in price.
On top of that your car is worth more, win, win.
Naturally the reverse is sadly true, but moaning gets us nowhere.
Put a few gallons in when the price is up and fill it when the price is down, that’s about all you can do.
You could walk, cycle, use public transport but who wants that hassle?
