Having recently bought a 2.0 HDI Elddis Firestorm,I find Im getting 27 MPG ,is this reasonable or should it be better.I know it depends how heavy my right foot is but I think Ive been driving in a reasonable manor,ie keeping the revs down before changing gear and cruising at 55-60. Any input gratefully recieved.

I don't know but 27mpg sounds good. Can't do the maths but we came from Dunkirk to Leeds on 3/4 tank and I was really pleased. Same mph as you I would say.

Reasonable for a coachbuilt doing the speeds you mention. Expect fuel consumption to increase on urban work and drop when on motorways if you keep the speed down. Watch out for headwinds as you will probably compensate by pressing down the accelerator and using more fuel. You'll be very lucky to hit 30mpg but be sensible and you'll avoid 22mpg.

Keep the weight of the van to a minimum. For example, travel with a 10 litre container of water for two adults rather than full on board water tanks. Empty your waste tank and cassette toilet when leaving sites. Load personal belongings with 'need' in mind not 'just in case' so that you do not carry any excess e.g. if there are two of you, do you really need 6 cups, plates, dishes etc and enough bedding for a refugee camp?

Keep the tyre pressures to the recommended level. Choose your route carefully. Sometimes the longer route will consume less fuel if it is flatter and not in urban areas.

In time, you'll be able to use your own experience of the van to find what suits you.

And I'm really pleased you've taken the plunge now. I wish you many happy trips.

Can I just add that its not really the sped that saves fuel, it's the engine revs (2500 to 3500) or more precisely the depression (vacuum) in the air intake.

As you accelerate the depression increases and draws in more fuel but when you reach the type of revs indicated above the depression falls right off and obviously draws less fuel.

This ideology still works fuel fuel injection.

If you really want to drive and save fuel get a vacuum gauge fitted and drive by that.

I had forgoten about the vacuem gauge,we used to have them fitted years ago, When my father taught me to drive in the mid 60s he had one fitted in a Ford Pilot and I was taught to keep an eye on it to save fuel.
When I passed my test and was allowed to drive the family car on my own I of course wanted to see how fast it was...did that car cost me some cash not driving by the vac guage.:cry:

no not just Reasonable but more of a miracle.!!!::bigsmile:

We get about 22 mpg on our 2.8 and on our old 2-0 like yours 23-25 tops. I must be a speed freak :winky:

Not sure what happened this weekend but achieved the worst ever mpg since the van was new, but I did have 5 seats full with the A/C full on in back and front so shouldn’t really complain I guess.:Eeek:
On a 200mile round trip mostly 6th gear I only managed a thirsty 35.9mpg from my 2.5ltrs. :Sad:

:ROFLMAO: stick the roof up as in your pic Buttons ( more like a c/b )and watch the mileage drop :Eeek::thumb:

In our Elddis 2.2HDI we managed 28mpg going to Scotland but it was Motorway/A road all the way. We went to West Wales not long ago and it dropped to 23mpg, still fair bit of motorway but then also lot of winding roads.

I'm sure that I would have done that by now if it wasn't for the loud buzz when you start off.
I'll have to get a buzzer for the dog as I sometimes hook him on the tow bar and forget him. Got as far as the site entrance once before the kids spotted him. :pray: Didn't effect the mpg but there could have been some additional drag if we hadn't noticed him....:Smile:

I dream of 27 mpg :cry: when I thought we were getting 25 and eventually found out I was only getting 18-20 I was well disappointed.

Thanks to all for the replies, so 27 mpg is about right then .My last camper was a VW that had an LPG conversion and at 60p a litre Im really noticing the difference :whatthe:

This ideology still works fuel fuel injection.

If you really want to drive and save fuel get a vacuum gauge fitted and drive by that.

if there was a significant vacuum in a diesels inlet manifold there would be no need for a brake servo vacuum pump.

a diesel engines revs are not dependant on the amount of air in the manifold, there is no venturi to create a vacuum, and the fuel pump alone controls acceleration and speed.
on a basic diesel the throttle cable controls the pump...not the air inlet.

plus, the turbo will increase manifold pressure above atmospheric so negiating any vacuum measuring device.

petrol engines, on the other hand, are exactly as you state.

Find out where maximum torque is in the rev band and try to stay there, too low is as bad as too high sometimes.

I see the thread has moved on to "how to get the best", but I just re-filled my Autoquest 2.0 HDi for the first time since we bought it, and I managed 30 mpg, based on a fairly wide variety of roads.

I have always worked on the basis of smooth. plenty of anticipation to maintain momentum as much as possible and keeping the throttle pedal as high up as possible.
