I don't mind spending, it's just that I have an obbession with MPG!!! I'm like one of those people who use 50 bars of soap to wash their hands each time, only I do it with checking MPG. I have always done that and I don't know why! I guess it comes from the time I got my first ever car and didn't earn much, every penny was a prisoner then and I haven't ever gotten rid of that mind set!
I think there are two US gallons left in the tank when the light comes on which is about 7.5 litres. Their gallons are smaller than ours.
Yeah, with F1 cars, were every ounce is accounted for!
