Shocked by difference in fuel consumption (1 Viewer)

[Scout]

After all this advice, I think I'll go and take the m/h out just for a fun run this afternoon, it hasnt been started for a good few weeks

 

[hilldweller]

70 mph (2500 revs) - 23mpg
57mph (2000 revs) - 30mpg

A little less speed, saves a lot of fuel

Now consider what driving into a 13 mph wind does to you. 13 mph is not much of a wind.

I don't believe you, I've never seen a Fiat speedo that accurate, they are normally +10-12%.

At speedo 72mph mine is travelling at satnav 65mph - which is my normal cruising speed. At that, towing the Smartie on a trailer, I see 21mpg to 23mpg. 2005 Hymer 2.8jtd.

Hello All

I am new to motorhoming, having bought my Rapido in May 2015 and used it only occasionally due to a persistent problem with it not starting. Anyway that is resolved now.

I have had a remap on my Fiat Ducky 2.3 L and it makes for better all round performance and the mpg is hovering around 30-32.
Off to the garage to fill up the tank for some real mpg tests

All these amazing mpg figures !
I am really rather jealous ... On the way down here to Beni we averaged ( not on the computer but actually noting and working out our selves ) 20.6 mpg

I have bought with me the latest offering fromTorquing of Diesel and will be running back home with that fitted.
I shall do the same calculations and report back on mpg achieved with it fitted

Forgot to mention..
Chieftain tag, 2.3 lump, 5.25 tonnes plated, fully freighted, with. Cruising speed of 54 mph as set on the gps not the speedo

Well jel is me. Although I have only done 803 miles so far, my trip comp says 18 mpg. Massive overhead cab though and only driven in this recent bought of windy weather. I only drive at sat nav speed of 56 ish - can't see speedo anyhow. Hopefully this will change and improve soon. 2.3 x290 euro 5+. No chance of soothing up as always changing down on hills

Hi Martin
To be accurate the mpg at 70mpg was only 19
It was the off motorway bits, plus any other slow bits at either end that increased the average to 23

Regards

70mpg?...You wish!

I am still amazed at the speed some enjoy driving at even when towing. I have my trailer with me most times and at my normal speed of 55ish i see only a small drop in mpg 1 or 2 mpg depending on the road. And speeding with a trailer on is a really good way to get pulled.

I use this road trip app on my iphone were I record each fill up and it gives yearly costs, mpg etc. These figures are for a 2015 Rapido A class 3.5t with the Fiat 2.3 150bhp, not bad mpg IMO as the engine is new, I drive at the speed limit and it was blowing a gale every time we went away in it.

Now compare the above figures with another of my vehicles which also has the aerodynamics of a 3 bed semi, the Land rover Puma Defender

I only use where available BP ultimate fuel as an ex diesel mechanic this fuel does everything I need without adding any additives, extra lubrication and keeps the injectors and fuelling sytstem clean plus the engine clatter is reduced on the Defender.

Always worries me in France as they tow at 130kph ! Bad enough with a car on its own.
