Hey all I've got a 1997 S1 VT Calais with 3.8L ecotec motor. From driving locally, around glenwaverley, clayton, knox etc, not in peak hour traffic, the best economy on the trip meter i can manage is 15.3L/100k's I'm keen to find out what other VT Calais owners get. For me this economy sounds too high, 12-13 is more realistic. And this is without me pushing it hard, its with me driving it grandpa spec style. Anyone shed some light on this? Cheers!
