Default Fuel consumption - MPG

Hi,
Not sure where to raise this question, so I thought I would raise it here and see how I get on.
I've just calculated my fuel consumption for a Fiat 2.0 JTD engine pulling a 2.1/2 ton Motorhome, Mclouis Lagan 410 and Iím getting 23.8 MPG. This is based on motorway driving conditions with an average speed of 60 MPH and the rev counter around 2500 revs. I could easily increase my speed but Iím certain my fuel economy would suffer badly. I've thrashed it before over 50 miles or so, to find I was only getting 18 MPG.
I have recently had the ECU Chipped which has improved the smoothness and pulling power quite considerably, especially when going up hills.

My Motorhome is at the lower end of the market and compared to some of the monster we see on the road and I canít help wondering how others find their fuel consumption. Our MH is only 3 years old so I think it will be reasonably fuel efficient and would be interested to know how other users get on. Oddly enough whenever I talk to dealers and the subject of fuel consumption is raised they appear to be a little evasive in their response.

Anyway, I would be interested to know if Iím doing as well as or better than other owners. Are last years models giving good fuel returns, Iíd be interested to know.

All The best,
Philip.

Fitted a Steinbauer P box to mine, www. steinbauer.cc around 28mpg on my Fiat 2.8,far better pulling power especially on the hills,brilliant I think and would recommend it,

Hi Philip
My van is essentially designed as a working van. It's a '98' 2.8 turbo diesel Iveco panel van conversion. We weigh in at about 3.3 ton fully loaded for a trip.
On a recent trip down through France and into Spain, mainly on motorway class roads, we averaged 27 mpg if we stayed at about 2500 rpm which gave us about 60 mph, but that dropped to 24 mpg if we did a lot of 70 mph (over 3000 rpm).
Over the whole trip, including climbing up through Andorra from the Spanish side and a fair bit of 'sauntering' about off the major routes, we averaged around 25 mpg.
Cheers.
John.

Hi I have an Autoquest 140 with the peugot 2.2 100 engine this returns
50mph 33mpg
60mph 28mpg
70mph 23mpg
This vehicle has a trip computer fitted this has made no end of difference to the way I drive as I can now see my money disappearing out of the exhaust.
My previous vehicle was a Swift Sundance 500 Fiat 1.9TD this returned 23mpg on average.
Before that was a VW T25 1.9 petrol which returned 25mpg .

my 2.8tdi returns around 26mpg at most 'normal' speeds. 50>60mpg A roads(always accelerating/decelerating), 70mph motorways (constant speed)

Our Hymer is on a Tranist 2.2. 130 BHP. It has never done less than 26MPG in over 4000 miles since new. If I keep below 60 Mph (2,100RPM) it can get 30MPG if its not windy.

Our Fleetwood Flair weighs in at about 7 tonnes and has the Chevy 6.5 TD engine giving 190 BHP. We used to get about 15 MPG from our previous RV (measured over an extended trip in France last year) however this RV spends soooooooo much time in Travelworlds workshop that it is difficult to really know precise figures.
I did check it on one trip that we managed to actually make and found that the consumption was about 6 MPG (even though the brakes were definately not binding, were they Simon???) but we cannot tell you about fuel consumption at speeds over 55 MPH because it will not go faster than that unless you go downhill.
I fully intend to check this once we get the RV back from the Dark Star at Telford.
