Miles Per Gallon?

Hi...

I have had my C2 for a few Months now, love it to bits, however, was curious on how many MPG other owners are getting compared to me? On long motorway journeys, I can get about 35 mpg, however, in town etc am getting about 16 mpg and this is taking it very, very easy [:(]

I would appreciate any feedback.

Cheers!!!!
 
sounds like thats about right-on my 996 i got 15-16 round town and 34ish on a decent run
 
My figures are much closer together.

Motorway approx 24.3
Town (although with small amounts of A road) approx 21.5

So dependent on how much stick you give it....

Edited to add: My figures are from full tank loads recording odo reading and noting litres I put in tank to fill it up. I'm keeping a log to see if I can see a difference between fuel types over a long period (I always try to get 99 but much of the time can't because it's not available in the north of Scotland)
 
I have never been able to work out the MPG, although I have been aware that it can vary tremendously. Motorways are where you'll see the 24 -32 MPG when driving in sixth at 70/80 mph. London to Somerset over 300 miles to the full tank and still enough left to lark about in order to find a Shell to fill up. Scratched my head a lot, couldn't work it out then, can't work it out now av. is generally 250 miles to the tank. City/ motorway driving.

City only driving reduces all MPG sensibility with Ken Livingstons enforced 20mph imposition.
 
When i drive around town on short journeys, think i average around 16mph (so the onboard comuter says) - usually the longer the journey the economy steadily increases, but on the motorway at a steady 65-70mph, usually get between 28 and 32mpg, or even more if taking it very very easily in roadworks speeds of 40mph.

Hope this helps.
 
Similar to others - low 20s in town, mid-high 20s for other roads.

I also found that using 98 RON petrol adds 2-3 mpg to my figures compared with 95 RON. Even if you ignore the manual/expert advice to use 98 RON whenever possible, it works out better value per mile to use it.

No on board computer but I do a manual check on each fill up - low to mid 20's is average .... apart from a trackady at Bedford when I filled up before I left and filled up when I got back ..... below 10mpg!
 
An easy way to work out mpg is to fill up with 45.5 litres (10 gallons) soon after the fuel warning light comes on and reset the odometer. Divide the odometer reading by 10 next time the warning light comes on, and add another 45.5l.

> 25 mpg on a motorway would be nice. Before the engine loom re-wire (the Porsche recall) my car would do high 20's on a long journey. After the re-wire its consumption rose by about 10%. It's been checked by an independent specialist, and the lambda sensor has been checked recently, it passes its MOT easily. So there's nothing obvious to explain why it's thirsty. Ideas welcome.
 
I used to get around 300, but had the mass sensor and some other sensors replaced and now it's clocking about 350, same as Maurice. Most I've had was 375 on a run down to Millbank.
 
Guys you are going to think I'm mad, but I've been logging every tank of fuel I've put in my car over the last 15 months, always filling it to the brim and noting the mileage and the octane I put in (I try to only use 98/99 but often have to put up with 95 up in the Highlands).

I put all this in a spreadsheet and calculate (from knowing the tank size so how much of the last tank fill was left) the exact octane mix in the tank (so half a tank of 95 and half a tank of 99 means I was actually using 97 octane). I then work out what MPG I get on that tank load next time I fill up....and plot it in a graph.

Anyway, it's bad news for anyone who wants to pretend that it's more economic on fuel to use 98! Of course it won't change my habit - I'm sure my engine will last longer on 98[:D] and I know I can feel more power on 98[:)].

Could just be that, because I can feel the power on higher octane, my right foot gets heavier to enjoy it....
