Hi, I just got the 2017 1.2l petrol auto n-connecta and I've been driving it around town for about a week now on short trips of up to 5 miles. And it really bugs me that the average mpg I'm getting so far shows as 18-19mpg. I was expecting north of 50 when I bought the car, so that is quite shocking to me.
Do I need to do more miles to get a better calculation of the average or should I be worried enough to take it back to the dealership?
Has anyone had such experience?

hi yes motorway driving will push up your mpg more than trips around town, but don`t expect to get 50mpg with a petrol/auto as auto cars have always been known for poor mpg :cry:

Welcome to this forum

My petrol manual only managed around 34mpg. You never get near the "official" figures.

Even my Ignis can't get above 50mpg despite allegedly being a lot more frugal.

But sub 20mpg is dire...

Have you cleared the memory of the fuel/mpg/mileage computer ?

I cleared trips 1 & 2 when I got the car.
I've done about 40 miles so far and the average is showing 18.6 mpg. I'm inclined to believe it as the fuel gauge is very close to 3/4 from full.
I know I can't expect the official numbers to be real, but I was getting about 24mpg from my mazda6 (again a petrol auto) with a 2L engine.. surely this puny 1.2L engine can't be worse than that, can it?
I wonder if it could be some sign of an engine issue?

I have a fairly long trip motorway next week so I'll see how it does then.

I usually topped mine up when about 1/4 full.

The lowest fill-to-fill figure I had was 26.2mpg - that was all around town. I also had a 27.1mpg and a 27.8mpg below 30mpg.

Only once did it go over 40mpg - 41.7mpg on a gentle trip to Heathrow.

Around town I generally get high 20's or low 30's mpg in my 1.3 auto.
My absolute best on a recent foggy motorway run is 60mpg (this is the car's computer figure I did 55mph for about 50 miles)

I guess you need to find the time to get out for a long run before trying to find out whether there’s a fault somewhere.

Is that "Best" as recorded on the display when you switch off? Mine was 99.9mpg!

yes, you pipped me there, and I thought I was doing quite well with that score.
