I always run with elevated tyre pressures, which helps with economy. Mine are currently 38 psi all round. I ran my Fiesta at the same pressures for 5 years and 20,000 miles. No uneven tyre wear, fronts will do at least another 5,000 and rears are only half worn.
What sort of mpg are you getting on a run.
Short trips in town with an auto box and an old generation Ford 1.6 lump, I wouldnt expect much more than 30 mpg - I had a couple of Mondeos with that engine and didnt get much more than 30 round town with a manual box.
Air conditioning can hit mpg by close to 10% too.
When I towed a caravan with the mondeos, I got little more than 20 mpg driving at 50/60 on the motorway.
Ive enjoyed driving Fords over the years, but one of my bugbears has always been high fuel consumption compared with a Honda and a Vauxhall I drove in between.
Remember too that the B Max is quite heavy and quite tall causing a lot more wind resistance than a saloon.
In saying that, My 2 Fiestas averaged 45 mpg and my 1.0 B Max is averaging nearly 44 mpg over its first 1700 miles, but I do little driving around town nowadays.
Google economy driving techniques and see if using some of these will help.Edited by: cianpars
