Re: 159 1.8 MPI Fuel Consumption
Well, if it makes you feel any better I have a 1.9jts with 16000 on the clock, I do a town journey of 4.5 miles to work and I average 17mpg. On a warmer day it gets closer to 20 and in the freezing cold it goes down to about 14. I noticed that performance and economy are far more dependent on the oil temperature rather than the water temperature. So yeah, could a 3.2 be any worse....I don't think so. My old 147 2.0 used to average about 21/22mpg on the same journey so it isnt far out I suppose.
Talking about the official figures you are right about the rolling road and there being a set programme of acceleration, braking, stops and the like that all manufacturers have to use on a rolling road to 'create' the official figures.
