Short journeys = low mpg.

As Steve says, I think you have answered your own question

Does this 5 miles all consist of city driving? No free-flowing dual carriageway or motorway?

It will depend a lot on what type of driving you do, and how you drive it.
Stop-Start city driving does nothing for fuel economy, wheras a steady cruise along a dual-carriageway or motorway is far more efficient.

If you have a heavy right foot then again fuel economy will suffer, steady accelleration & braking combined with good anticipation can help your fuel economy.

Short journeys don't help either, I know with my Berlingo that after 5 miles the engine will probably just about be reaching it's optimum operating temperature. Most vehicles have cold start enrichment cycles and will actually overfuel until the engine reaches a satisfactory temperature.

27.7mpg does seem a bit crap though, how are you working out your mpg?

The engine doesnt really get up to temp.

ONLY doing that sort of mileage will take its toll on the engine.
And if you have a DPF, it ain't going to last long.

Set your trip, top up and do a good run-if theres no improvement then something is really amiss

[j90xxx]

Needs a regular good run!

Hi, I only do short distance & low mileage but I'm averaging 35 to 40mpg.
I made the mistake of using US gallon instead of UK.illyme:

So it's 1 Gall = 4.546L
