How you drive any Diesel vehicle, will vastly affect the fuel consumption. Diesel engines are all about torque, and are driven completely different to a petrol engine.

As a lorry driver, we are given assessments of fuel efficient driving, and our MPG is monitored constantly by the company. We are set a average of 8 mpg for a 38 ton artic, and if we do less than 7 mpg, the firm wants to know why. and we are assessed again.

Our Swift Sundance 630G weighs in at around 3600kg in working trim, and is 23' long, with a large overcab.

The 2.8JTD engine will, at a push return 25mpg, but I normally cruise at around 70mph (GPS speed,, so indicated 75 on the clock) and get nearer 20mpg.

That said, when we're not in a hurry due to restricted time off work, it easily returns 23-4mpg cruising around the lanes at gentle speeds!

I just chipped the engine, and no difference has been noticable, apart from the torque.

Pay us more ???? Thats a laugh.

Constant fuel inefficiency by a driver can result in disciplinary action.

Has it really got that bad Jeff? I have to say I am glad to be out of it and retired, even though with the firms I worked for I was always one of the most fuel efficient drivers on  the road, and incidently I get 30 mpg on a good run with my 2.8 jtd Ducato.

It all becomes clear!

This is why when I am travelling along a dual carriageway at 70mph about to overtake a lorry the driver will pull right out in front of me rahter than slow a little and let me pass before he overtakes.

hi all

have a  ford transit based chausson flash 03 it has a 2.0 l td engine  which returns 25-30 depending how I drive

My 2.8 HDI Auto-Sleepers Executive 2003 is a flying machine & thirsty. The last mileage check I did, returned app. 26mpg. Most of that was over app. 500 miles & mainly using the cruise control, which is a boon if you want to eek out the diesel. But if I drive it as I would my car, the mpg plunges, but she's fast.

I can get nearly 30 mpg out of my old Mk1 V4 transit coachbuilt.Its got an OD box and the heads and manifolds have been modded.

Maybe design hasn't moved on as much as we sometimes like to think.

Our 1985 Talbot Express Camelot -( the old 2 litre pushrod, petrol, Peugot engine ) - averages 28 - 30 at 55 - 60 mph -  - just hard work keeping the rust moth at bay - (perhaps that is why it is so economical ? - its a lot lighter than when it was new.)
