Just ran the first tank of fuel through my little 4x4. It got me 32 to the gallon (UK that is)

So I was wondering, just for a bit of an info bit.
How do you all feel about posting your Panda's details and what you last got on the MPG for a full tank.

The way I did mine was to node down the last 3 numbers of the mileage (131) filled the tank right up and ran it till the red light came on and checked it again (308) then, filled the car up again (25.46) and checked how many litres I had used. I then used a google search for UK MPG Calculator.

Mine came out at:-
1990 4x4 panda, 131K miles on the clock. 32 mpg. :D

I look forward to seeing how you all do (y)

p.s. it's a whole lot better than the 20 mpg i get on my other car :bang:
 
Mine's a 1000Fire injected...it usually covers 15Km with 1 litre (atleast), which equals to 35MPG, more or less :eek: .But mind the lambda sensors lose their sensibility with the mileage, and especially if the engine burns lot of oil (not my case fortunately :D ).Another point which could badly affect the economy is the lack oif the corrugated pipe that allows hot air to enter the intake...probably the electronic management adjusts the mixture to be a little more rich than required. Any opinions about this?
 
My injected CLX usually averages over 40mpg - mostly urban.
I have figures itemising fill ups and indicated mileage over several 1000 miles - will post back later, time permitting.

OK, I've lost a sheet in the middle of the book, but here's two full pages:
from 71828 to 76752
4924 miles, 542.39 litres at 4.54609188 litres to the gallon is about 41.27 mpg.

and from 82490 to 88004
5514 miles, 560.86 litres at 4.54609188 litres to the gallon is about 44.69 mpg.

There are notes against the second sheet - Esso, BP, Shell etc, which it does seem to prefer to supermarket own brand: slightly more go for less pedal, in this particular Panda - and it must be said it has improved a lot over the 20000 miles we've run it so far (70500 to 90500 in round figures).

As they say, your mileage may vary... and the 4x4 will be less due to all the extra cogs being turned around.

ENZO !...Fit the 'little corrugated pipe' ! You are wasting shed-loads of fuel my friend.

Sandra's 'dogcar' (Panda 'Panda' 4x4 two-seater conversion) is doing 25-30 m.p.g., but virtually all of it's driving is stop/start, short haul work in the hills and accross the moors. Plus the fact that, although she is a mere slip of a thing, I'm 17 stone and there are three dogs in the back !

My Sisely is running at 30-35 m.p.g............25% country driving, 75% City work.

It's the tax and insurance we love.......one of us is registered 'disabled', so joint road tax is £120 per year and the cost of insuring the PAIR through our broker is £220 per year !!
 
Well so far the last 3 fill-ups have all got me 28mpg. This does not seem right for mostly driving at 60 too and from work, so i think i'll have a look at the plugs and see if it's running a bit rich.

This can be this afternoons job as i'm off to bed after nightshift now :yuck:
 
On my mammoth European tour last summer, in my Sisley 4x4, I started off getting about 40mpg but by the end I was getting about 45 mpg. Don't ask how it changed!!

You have my greatest sympathies with the night shifts.


Anyway, with regard to the Panda:
tyre pressures - too low creates lots of drag.
air filter, change it if you haven't recently done so.
check the vacuum advance unit - it makes a big difference, as does accurate ignition timing.
dragging brakes are bad news too - check for unusually hot wheels after a run.

I wouldn't have thought the carb should be too far out, presuming the last MOT pass was genuine - if anything I'd expect it to be adjusted slightly lean from best performance.

I'm fairly certain it aught to do better than 28mpg...
 
Hey Latman,
I remember you doing your trip....good to hear from you.

sandra's 'dogcar' was turning in some very bad MPG lately. This was entirely due to overenthusiastic self-adjusters. 'Tis like everything else in life............it's the sum of the parts that create the results.
Kindest,

I think 15 km/litre is better than 35mpg.

multiply the 15 by 4.54609188 (litres to the gallon) would give 68.1913782 km to the gallon.

and multiply by 0.621371192 (miles per km) gives about 42mpg.


Regarding warm air to the intake, I'd argue better volumetric efficiency with cold air - which the injected versions can use into colder weather than carbs without icing up - but how much more efficient I couldn't say.

AFAIK, in terms of richness - injected version run close to "ideal" to keep the emissions down - a carb could be set a bit leaner, but you'll start to loose maximum power if you over do the lean mixture a bit, and burn valves/over heat if you over do it a lot.

my 1l fizz injection on an L-plate get 130ish miles to £10 of petrol, and thats driving with a heavy right foot

Depends on your fuel cost - it's been around 80p/gallon around here until recently, which would give you about 47mpg.
A bit less if the fuel is dearer.
 
Well I sorted out the Mixture and ran another tank full through and it's still doing only 28 MPG :(

Anyone any ideas please. Whats this about a lambda sensor? Would that kill the MPG in such a way.

Checked all the other things like the corugated pipe, vacume advance, brakes, Filter ect already mentioned.

Thanks in advance guys.

Yes, but - I don't think the 4x4 has one:
I thought the 4x4 had a carburettor.

Lambda sensor is feedback relating to exhaust gasses for engine management on fuel injection systems: low (voltage) is lean - if it fails giving no voltage the engine management gives more fuel than required.
 
My 4x4 has 30K on the clock. I am currently using it for driving to the office which is a journey of 27 miles each way which gives the engine plenty of time to warm up. My mpg is regularly 44-46. When I bought the car I did have to drive it 300 miles home! (Don't ask) Because the car was an unknown quantity
when I bought I took it easy but a steady 60mph returned 51mpg which I was pretty pleased with.
Mike.
 
Well it's not that then as yes it has a carb :(

Oh well back to the drawing board. Anyone any Ideas pls as to why the low MPG?
 
Nope tried that too. The trip to work is 20 miles and the clock reads that every time :confused:
