Just finished the first tank with the wheel covers on: 5.15 L/100 km, 45.69 mpg (US), 54.88 mpg (Imp).

Only marginally better than the previous tank (5.19 L/100km). On the bright side, I expected this tank to be pretty bad, since I did a higher than normal proportion of city driving this time. So maybe the wheel covers made up for it on the highway. Too soon to tell.

I've also got Torque working really well now. Its prediction of how much fuel I had left in the tank was exactly right.

Also, this was my first tank over 800km, and according to Torque, I averaged 4.7 L/100km (50 mpg US, 60 mpg Imp) on the 35km part of my commute from my house to the gas station this morning. Nothing like running on fumes to promote eco driving.

PS. This is fun!
