And before anyone starts saying "That can't happen!", of course it can. Little tweaks when nobody's watching. And it's no wonder when our fuel is so heavilly taxed in this country. The stations only earn about a penny a litre. It's disgusting how we're taxed in this country. But you'll all vote for lower income tax next election, I bet, and then be robbed in the price of your goods instead.
Go ahead, calculate your fuel to the n'th degree. That's not where the wallet heammorage is occuring. |
5l cans are a nominal capacity based on the temp of the fuel & to allow for expansion so yes on a cold day you may squeeze 6l in but then leaving the tank full & letting it get warm could end up with it leaking.
Garages have their pumps tested by trading standards & can be heavily fined in the event of pump's dispensing less than the indicated fuel. IIRC the tests are also random & the garage isn't pre-warned.
