yet i can pull 14.00's at the strip?
go figure no i'm just a smart driver.
as sidewaymambo said its how you accellerate. do it smoothly and no violently and you'll get better figures
plus 90% of my driving is on the highway cruising at 100kph. on my car thats about 2600rpm. i get these figures all the time. yes they go down when i give the car a burst or 5 during the week. but then it only drops to 550 per tank.
WA has better fuel as well its refined different as we have harsher fuel laws. Our petrol burns cleaner therefore giving more power and economy since the fuel is working more efficently in the engine.
