Is it the 1 litre Blue Petrol or the 1.2 litre manual or the 1.2 litre auto.
The driving style of the driver…steady and drives like a nun or drives like a lunatic, or somewhere in between.
How good the driver is at getting the max mpg out of his/her car…level of experience etc.
Where he/she drives it…town, country, motorway, mixed…. etc.
Is it used for short runs, long runs, lots of cold starts or all day at 70mph.
Shell? BP? Tesco?…..everyone has their own views whether it makes a difference.
How old the car is…ie. fully run in or still new.
How many passengers – driver only or five up….and empty or full up with gear/luggage etc.
Presumably no roof rack or bars as that makes a difference too and presumably no binding brakes (as mine were until they fixed them).
And finally…to be honest…. if you take the time to use the search facility on here you’ll see that it’s been the fairly constant subject for discussion, to the n’th degree, for the past four years.
There is no answer. I almost always get 32mpg out of my auto. doing the sort of journeys I do but others report all sorts of mpg doing the sort of journeys they do.
Others may have different experiences which they may wish to share with you.
I purchased a 2009 1.2 Classic i10 recently and have just refilled the first complete tank full of petrol I used. I reset the trip meter at the first fill then using miles covered and the second refill quantity of fuel, the fuel consumption calculated was 48mpg. I am very satisfied with that.
