Bongo Fury

Hi all bit of advice needed please, I have a 2.5 diesel bongo 2wheel drive, she is only doing at best is 20 mpg, there is no diesel leak that I can see nor can I smell diesel, performance wise she pulls fine, she has done approx 85000 miles, any ideas please, thank you.

What sort of journeys are you doing?

Motorway, 50 mile commute, short hops in hilly country?

Is this a sudden drop from normal?

If so, what have you been getting previously?

Hi a lot of my journey are short one's and it is quite hilly around here, I was getting about 28 mpg. On long trips it appears ok. Cheers

28 mg sounds about right, first thoughts are air and fuel filters, although 20 on short, hilly, runs doesn’t sound too bad.

Others may have some thoughts.
