MPG i-shift MPG experiment

Kremmen · 4th May 2008, 08:40

Normally, in full auto mode, I get about 39MPG (calculated) but the trip comp shows around 44MPG, been doing that for the last year.

Just for fun* I drove my i-shift totally in manual mode last week.

The trip comp showed 45MPG and I actually got 44MPG (calculated).

*not really fun 'cos I'm a lazy git

Hey, congrats...2000 posts!

Anyway, back to the theme....

When I tested mine by filling to the 'cut-off', driving over to relations in Rayleigh and back, re-filling to 'cut-off' (using same pump). I found that dividing fuel by miles travelled it equalled the computer almost exactly. 43mpg.

Mind you; that was mostly motorway travel (M1, M25) at a fairly steady 70mph, although we did have a couple of short holdups.

Oh yes - I'm a guru, I've been called worse

In auto mode it's always about 5 MPG out. I also do over 90% of my weekly mileage on motorways/dual carriageways at about 70mph so that's making no difference to me.

Kremmen what mileage have you done in your civic? Ive done 2143 and in my type s gt ishift im only getting 27.6 mpg. I also drive in auto mode most of the time and rarely put my foot down as too many cameras about...how can i get mpg figures as good as yours?

Hi

I've done 12K miles but that is a red herring in as much as the engine freeing up after any number of miles.

I've been keeping a spreadsheet since the car was new. My weekly journey is always the same from West London to Surrey which takes in 2 motorways and 2 dual carriageways with the final bit being a 50mph free flowing A road.

Throughout it's life, my MPG has been an indicated 44mpg but spreadsheet calculated to be 39mpg.

...and I've only done 6000 miles in my EX i-Shift; so it may even get better.

Mind you, I'm not driving an S GT; if I was then I could see my MPG being a bit less!!

PS:....and if I were a bit younger!!
