MPG for my 04 plate ZS180
I've just driven from Ilse of Sheppey in Kent to Bodmin in Cornwall which was a 285 mile trip. I filled up the tank before i left and filled it up again when i got here, i used 38.20L. Which if my maths is right, to get gallons i divided the 38.20 by 4.5 (U.K. gallons) which equals 8.48 gallons! Divide the milage by the gallons (285/8.48) which equals 33.61 m.p.g. Does this sound reasonable for a 2.5 V6? I'm gonna re-do the same on the way home on sunday just to clarify the numbers! I had the climate control on most of the trip so not sure if this would make a difference? So i'm gonna keep it off on the way home.

What else were you carrying, passengers, boot items etc? Speeds and driving style? Could be average but alot depends on the data. If carrying more than the normal load then it is good.

I had 2 dogs on the back seat, my mother in the passengers seat, a fair bit in the boot but nothing too heavy. On average i'd say about 75/80 mph on motorways . Not sure on the style, i was following my wife in her ZS 120.

When you say 75/80, was that an indicated speed, or a speed given by your satnav?
As the ZS speedo can be very out at those speeds, very out indeed!
All things considered, 33mpg on a run seems a little low... I would have been expecting 35-40 rather than 30-35!
Maybe worth a trip to see Ralph at EMS to get a full service done?

That was indicated speed. Just had it serviced at EMS, always like to make sure things r ok before a long journey. I'm gonna get a Scan Guage for the car so i can keep and eye on things!
All things considered, i'm quite happy with the performance of it. I didn't use much more petrol than the wifes 120 so not too bad!

Plugged the scangauge in for a short drive - the speed reading matches the GPS of the sat nav which is about 6% less than the speedo, strange as the scangauge uses the same source as the speedo.

That's what I discovered on the way to work yesterday using the OBD software on my phone (just had my Bluetooth OBDII key arrive!)
Have you also noticed that the rev gauge is out aswell compared to the ScanGauge?
15psi boost baby!

The litres should be divided by 4.54 to be more precise.
285 / 8.414 = 33.9 mpg average fuel consumption.
That's good going on a 180 with some load.
To get anymore out of the 180 you would have stick at 50-60

Shep mate - did you get the figures for the 120? That would be an interesting comparision.
As for your 33ish mpg, that is resonable for the 180.
Several times a year I make the same trip from West Sussex to Stoke on Trent and back -
Driven with ecconomy in mind - gentle acceleration, as little brakes as possible etc.....31 mpg
Driven fast as I was late..........got there much quicker than I should........................29 mpg
Driven normally with the flow - normal use of acceleration and brakes........................33 mpg
over the 400 mile trip that still only makes a few £ diffrence, the real cost is local driving, as little as 20mpg, I got my scanguage yesterday so I'll be doing some real time studies on the diffrent styles of driving on and off boost (soz, VIS).
Incidently I have done the trip to Stoke in our old 1.4 R100, used about the same amount of fuel!
