Something weird with my '06 9-3 Aero sport combi. Driving at 100 Km/h gives around 12 l/100 Driving at 120 Km/h gives 11 l/100 and 130-140 average gives
10 l/100. Those numbers comes from 2 runs : one of around 1800 Km in 2 days and the 600 Km today.The fastest you go, the less gas you take. Crazy. At 140 Km Rpm is around
2300. That might explain things a bit.Any other explanation ? like my computer is crazy ?
