Depends on what car I drive determines if I pay $50 a week for fuel or $350 a week at the current prices
If I'm wheeling my Caprice I use a bit over 200L/week of 98 so I tend to only use it on Fridays and weekends or when I feel like being anti social and annoying everyone.
When I was working locally and driving my Focus I'd only fill it every 3-4 weeks
I'm getting bent over and spending more than $2000 a year just on tolls, who cares about the price of juice thats the bigger bug bear for me.
