You cannot do much about it,,, its a heavy lump and the 112 has never been that good on fuel. just drive it with some fore sight and remember the difference in the fuel cost is not very much say in 5k miles over a re car that is 20% better.

I know a man who spent £8k changing his car to get one more economical when his annual mileage was only 3k miles per year, he will have to live to be 200 years old to get anywhere near even

here's the trick-cyclist method I use

find a motorway or dual carriageway with a pretty steep, pretty long hill. Get your self up to the top and make sure you are pointing at the downhill bit. Drive the car at the appropriate safe but nonetheless, motorway-type speed over the crest and down the hill. Take your foot off the accelerator. reset the instant trip fuel computer.

I did this on the M62 last week, going from York's to Lanc's. By the time I got down to Milnrow , about three miles, the car was doing over 40mpg.

My brim to brim figures aren't that bad either. A good fast lengthy motorway run give me about 29mg. My usual city commute gives me 23 mpg, with all points in between available.

Malcolm's tips are right on the money. Try and anticipate what goes on ahead, minimising braking and accelerating. Clear roads are a boon.

if you buy big petrol engined cars the day to day running cost..fuel.. is going to be an ongoing drain on the finances.. Going diesel for bigger engined cars is more upfront, but the day to day running costs will be easier to live with.
I can only suggest you spend a few quid on a good service and see if it helps
