I think I've posted before but after a bit more driving (at the 33k mark currently) ...

Mix of 80% freeway driving at 100km/h and 20% surburbian in between, manage to do about 8.1 - 8.5L/100k in an automatic. However, I accelerate pretty slow off the mark and have a very steady foot on the throttle to keep fuel use constant (or use cruise control).

Let my mum drive my car for 200km and the way she constantly accelerates / decelerates (even during normal driving, she has an unsteady foot on the pedal) and the meter read's 10.2L/100km.

My car's run BP ultimate since i got it from the dealer, using Mobil 1 gold 10W-30 and have new Yoko C-drives at 36PSI if anyone wants to know the other variables :P
