How many miles per gallon do you get? (1 Viewer)

[wasp]

I get about 25 to the gallon in my Transit 2.4 DuraTorque engine thingy.

 

[Madmark62]

In our limited experiences so far we are getting approximately 22.98745637282 to the gallon, approximately of course, not that I have got neurotic or anything about running out of fuel !!! Oh NO!!!!!!!!!!
Forgot to say Renault 2.068 litre diesel engine of 26 year old vintage, pulling about 3.1 tonne with 80 bhp.
I dont reckon that is too shabby really.

mpg.

you missed the point.
petrol stations only sell by ltrs or price

 

[Terry]

How do you work those equivalent MPG figures out, I've never quite understood it.. Thanks

Hi Jim -you use the price per ltr/gallon of petrol then the price per ltr/gallon of gas which would give you say 2 gals of gas for the same money as a gallon of Petrol
IE (just for figures)
Pet = £2 A GALLON =20mpg
Gas = £1 a gallon=2 gallon for £2 =40 mpg
in reality if your van does say 20mpg on petrol it does around 17/18 mpg on gas or in the case of a RV
8/10 mpg on petrol and 6/8mpg on gas but seeing as you get 2 gals of gas for the same amount as 1 gall of petrol you are in effect doubling your mpg figure using gas =12 to 16 mpg
ACTUAL figures around here are 66 p per ltr gas and petrol is £1.32 per ltr so 2 ltr gas = 1 ltr petrol

BTW 27 mpg with roofbox -2.8 td Iveco
31 mpg without roofbox -more or less same 1500 mile trip with brim to brim fills

Always baffled me as well

I've had 3 Rv's done over 100000 miles in them never got over 9mpg in a petrol or 14mpg in the diesel at a steady 58 mph and a damn site less if I put my foot down.

Hymer 2.8 JTd at a steady 60mph 24 mpg over the last 4000 miles

Ahh but 4.56 litres make a real money gallon

I've just been on a run up to Glasgow from York, cruising at 65 mph and it managed 37 to the gallon. Overall for the one week trip it came out at 33.

9 year old Mercedes 313CDi, 30000 miles.

25 mpg towing Smart & trailer 19mpg

Since, remapping (£250) towing 23 mpg or 25mpg if I use the better diesel.

Also, much more power. Acceleration & response towing is as if the Smart is not there.

any thing around 20mpg is good when you think how much a night you pay for B&B
my 5* RV would cost around £50 a night so i can go quite a distance for the 20MPG i get

 

[Destination Unknown]

Not enough

Fleetwood Bounder American Rv. Ford V10 6.9ltr. Petrol with Lpg fitted.
Petrol around 7 mpg Lpg 14/15 mpg.

We are Full Timing so the Rv is fully laden and we tow a car on a A-frame so we are quite happy with mpg.

I get it, so essentially if LPG were as efficient as Petrol and half the price they double what they get and call it equivalent MPG.

What the percentage is the LPG's efficiency compared to petrol. Is it around 80%? If so, to get equivalent 20 after the conversion you would need to be getting around 12mpg before it, is that right?

:thumb: about right
To make a gas conversion work/pay you have to do a lot of mileage in a rv :thumb:
say 2.5k to convert a v8, that buys a lot of petrol-we won't go into gas knackering up your engine/heads after about 80,000 mls

exactly correct ..

the average price for LPG is 76p .. petrol 132p

and as you rightly say, LPG is only 80% efficient compared to petrol, doubling the MPG does not give you the equivalent petrol MPG.. that is a hogwash

,... for that to be true the price of LPG would need to be less than half the price of petrol

I did the figures for this some time back and worked out the payback time on an LPG conversion was about 20k miles.. and that was when LPG was a lot cheaper.. about 50% the price of petrol.

It makes no economic sense to pay for an LPG conversion unless you are doing that sort of mileage annually .. and with the price of LPG climbing faster than other road fuels there will soon be no economic benefit .. LPG has had it's day as being a cheaper alternative..

Thanks for all that wonderful input.

It looks like I'm not doing too bad with my consumption rates, but I am definitely going to do as some of you more experienced MHers have suggested and start calculating it based on the fuel I use and the miles I cover, rather than just relying on the onboard trip computer.

And I definitely agree with everyone who says it's about the pleasure it brings and not the pounds spent on fuel. You are totally right. We've only had our MH since July and already I have to say that it is the best investment I've ever made.

Thanks for helping me realize I'm in the right zone

mpg

2.2 HDI peugeot. 32.7 mpg over last 4000 miles. But it does weigh only 3000Kg (3 tons ish)

[Road Runner]

I was getting around 6mpg on my RV on LPG with latest Romano sequential system fitted so minimal LPG MPG loss................mind you lugging around me the mrs and 2 Great danes plus endless lockers full of junk.............

Paying around 56p pl plus VAT at countrywide farmer's

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Now seem to be getting 28mpg on Tabbert with first run..........

 

[Mr Colpot]

With the 2.3 Rapido (3500kg although usually 3200kg loaded up) - we were getting 30-32 mpg

With the 2.8 Hymer (3900kg - not yet weighed it ) we are getting 28 mpg

Cummins 5.9 turbo diesel doing 14.5/15.5 per gallon on 100% bio diesel at .30p per litre equates to equivalent of around 60 MPG. What was I thinking about when I sold it oh:.
Peugeot 2.5 turbo diesel doing around 28 MPG on 100% bio at 30p per litre equates to 120 MPG....Ah now I know what I was thinking about.

 

[johnp10]

26 - 28, 2000 Bessie E745. Measured after 2020 miles mixed running.

Is any of this really relevant / important?
Does anyone go on about the mpg achieved by a motor bike? a speed boat? powered glider?
We are generally talking leisure vehicles here, and not comparing like with like in any case.
Leisure vehicle, simple principle:
Put fuel in....go....run low.....put some more in.
Dont worry about it, you're on holiday.

Dont get stressed, you'll buy the fuel anyway.

rover V8 3.5 ltr petrol 14-15mpg during last years trip to up yorks and co durham coast, on milage against gallons used. Quite happy cos as an earlier funster said think of what a b+b woulc cost its economical

apologies for post shortening Jim.

anyway, maybe in your neck of the woods Mate but here in sunless Scarborough, LPG was stable at 69.9ppl for over a year.

then it went to 74.9ppl for around 6 months.

now its back to 69.9ppl and has been since august.

three years ago LPG, here, was around 45ppl so an increase of 25ppl or 55%...how much has petrol/diesel increased in three years ?....almost 100%

Just got back to Essex from a few days in the midlands, to be honest, i could,nt give a toss how much jiffy i used. the memories we made the last few days, dont have value, niether will the ones we make in Spain next year.
The 2.8jtd remapped uses less under sixty than it does over......that'll do for me.
