economy to be better than I'm experiencing. Took it back to Berkshire from
Bradford, and done various trips in it (mainly motorway, sitting at
70-80mph), and I've only averaged 49mpg. Checked the oil and it's a little
low, and I'll be doing an oil change (and air filter + fuel filter) over the
weekend, so this should ensure that things are running reasonably optimally.
Thing is, I was hoping to average around 55mpg in it. Now I know that's no
massive difference, and the shape of the van is hardly the most aerodynamic
shape, but can I expect better economy at lower speeds?
The reason I bought the van is because the work I do is 90% city traffic,
rarely going much above 30-40mph except on the motorway on the way in and
out. A few questions:
Am I right in thinking that for lower speed driving (i.e. 40mph max) the
detrimental effect the shape of the van will have on fuel economy will be
The gearing is fairly high for a diesel, probably because it's normally
aspirated, and just not very powerful. It's doing 3000rpm in top gear (5th)
on the motorway - am I right in assuming that the economy around town
(providing there's not too much heavy traffic) should be a reasonable amount
better than sitting at 70-80 on the motorway? 3000rpm certainly doesn't
feel very economical.
Anyway, time will tell - people's comments appreciated.
