I just like to have her busy earning her keep. Mind you she sometimes objects to cooking my diner when she gets in at 10pm after doing her 'little run oop north'.

Re: Miles per Gallon

1.3 multijet 2005.
Generally disappointed with mpg particularly above 60mph. My old montego would return 65mpg at 60mph but this only gives about 57mpg . however, It is good round town at 56mpg .
Someone said that consumption was better with the 1.9 - but all the mpg numbers in these posts are even worse than mine.
towing a caravan brings it down to about 30mpg - despite other people's views this is not a bad experience provided that you are happy with 55mph. Caravan =1100kg gross .
Would the new 105 1.9 engine be more economical as someone suggested?

How are you getting these figures?

Re: Miles per Gallon

Figures on fiat from the trip computer which seems ok to me. Figures on montego from fill up tank method.

Re: Miles per Gallon

I used to own a pug pickup with a 2.3 diesel engine.
On the motorway I would average 50+mpg as long as I kept my speedo under 55. As soon as I cranked the speed above this you could see the needle move.

Having only recently bought my dobbie I have no idea what the mpg will be. I ran it 'till the fuel light came on then filled the tank right up - 47 litres - and zeroed the trip counter.
When the yellow light comes on again I'll have some figures for town driving - but I'm already ahead on my last car, having done 170 miles & still not hit the halfway marker.

Primehacker,

Treat the trip computer mpg display with a H U G E pinch of salt. The best way to get an indication of your car's mpg is to fill it up, note the mileage, drive it until it needs fuel, fill it up and then calculate the mpg.

(end mileage - start mileage) / litres to refill * 4.546 = mpg

The trip mpg on Mrs_G's Doblo is always 5 to 10 mpg out when compared to this method.

Re: Miles per Gallon

My M.P.G is steady at around 40-50 mpg. doesnt really drop on the mway stays in the 40-50 zone at 70 mph. Sometimes which is unusual wen i reset the trip meter after settling down. It reports back 52,53 mpg etc. There is a diffrence in fuel economy. Is it possible for certain petrol stations to have a higher grade of diesel or is there something else in it that enhances fuel economy?Better economy from the major petrol stations than the smaller ones.Always fill on the 94-95 p per litre

I know many people who refuse to use tesco petrol because it doesn't contain the detergents/additives found in many other brands & people report problems after filling - rougher running, lower mpg etc.
I always used their unleaded when they were cheaper but now there's the price match I use the big names - and now I'm on diesel I'm laughing, 300 miles & just coming up to 3/4 tank, all around town.

Re: Miles per Gallon

On the subject of fuel economy, I have magnets attached to my fuel lines. On my last car I saw an increase in economy from 23/24mpg around town up to 26/28mpg - depending on how I drove.
If I treated it like a limo (steady accelleration, gentle braking etc) I'd get 28 but so often the chavvy boy racers in their 50 fiestas (with 3k sound system) were often itching for a race.

I didn't do a trial without the magnets so won't know if there's an improvement but I know it worked wonders on the petrol & imagine (hoping) it'll give similar results on diesel.

I've seen first hand how great these things are on the water pipes round here & use them on my gas lines, central heating and hot water system.

Anyone else used them?

And people laughed when they said the world was round.

At my last place of work we had no end of problems with the supply to hot taps around the building (and the place was 8 years old!).
A company came in over the weekend & flushed strong acid through the hot pipes - but one pipe in the boiler room was so bad they had to cut it out, 4" diameter pipe & there was barely room to push a pencil down the middle because of the limescale.

The hot tanks had also suffered so these were replaced - two huge Strebel boilers, 8' tall & 4' diameter.
12 months later the company came to service the boilers. Out of the two boilers they took enough scale to fill a 300 litre metal bin.
Because of this - and the problems it would cause later, we had magnets installed on the hot pipes. The following year the scale they removed filled a 5 litre bucket, the year after there was nothing to remove because the magnets had stopped the formation of scale.
The guy who installed the magnets told me about all the other benefits - improved fuel economy in cars, flames burn hotter in gas boilers, scale reduction in water systems, pain reduction (eases toothache, backache, period pains, arthritis etc).

Had I not seen the improvement on the hot water system I wouldn't have believed it could work.
Having used magnets on my car's fuel system, I noticed an improvement in economy, I also used magnets for pain relief (bad arthritis in my wrist, magnets ease the pain allowing me to sleep better). Also used magnets to help take the edge off toothache & OH uses magnets to ease period pains.

They aren't 'magic beans' - although I can understand your scepticism but with all the miles you're dobbie is doing, would it really harm to try fitting a magnet around your fuel line?
It takes a tankful or so to start seeing benefits but what have you got to lose? 10 for a magnet. Mine paid for itself within a few months.

Re: Miles per Gallon

Sounds really interesting. I know that heating engineers fit large magnets to the feed pipes on boilers in our area because of the problem of very hard water. We have one on ours.

I was very sceptical when I saw them advertised & so steered clear. I actually thought it was some new age mumbo jumbo from the tree hugging brigade.

However, since seeing what the magnets did at work I was a convert.
The best tell is my kettle now never needs to be descaled & if my kettle is clear, my hot water tank must also be clear, as must my central heating pipes.
As I said earlier, they really help take the edge of pain and I had proven increase in fuel economy.

OK lets run a test. Mrs_G keeps a record of mileage covered and fuel bought. Will any old magnet do or does it have to be aligned with the fuel flow in some manner?

The magnet I have is a two parter, each half being a 'W' shape and the two halves being held together by cable ties. As you put the halves together they want to repel each other.
I bought this about five years ago, no doubt the 'technology' has somewhat improved with improvements in magnets.
