2.7 fuel economy

Hi all,

Just wondering what kind of economy those of you with a 2.7 are getting.

Recently my truck got about 7-8 km/l (~14 l/100km) with a mixture of open road and town, and a generally sedate driving style.

This seems pretty uneconomical, but it's my first diesel so i'm not sure.

If this is really bad i would appreciate any suggestions about how i might improve things.

There is no secondary mesh fuel filter in the pump.
The glow plugs are worn/maybe the battery - has trouble starting on cold mornings .
It has a miss around 2000 RPM on the open road.
Diagnostics indicates a high voltage level associated with the fuel pump, was told this means the fuel pump is worn.
I've done filter and oil changes.

Cheers :)

That's about what I'm getting in a 95 Terrano td27 auto.
Did Auckland to turangi with kayaks on the roof and a weekends gear in the back at 8.3km/L last weekend...

My best figures have been 10.2km/litre open road only (quite a bit of hill country too) with 92 Terrano TD27 maunal. Around town my economy is usually around the 8.5km/litre mark. It's been a little better since installing the 2.5" exhaust.

Very similar to me hilly country up here, so both 1994 TD27 Terrano, and Mistral I would get around 9.9 - 10.0 litres/100km going down to Tauranga I could get it down to around 8.4
