Hello,

I have just received my brand new Ford Fiesta 1.25 (82bhp) petrol engine car. I have a couple of questions and was wondering if anyone can enlighten me..

I know that a diesel engines mpg gets better with time. Is the same true of a petrol engine?


My brand new petrol engine Fiesta is only just getting 40 mpg. Now Ford gives a figure of about 50 mpg for combined driving and this, i would have thought, should be what i am getting. I don't just drive aroudn cities stopping and starting. I do a bit of town driving with longer motorway / dual carriage stretches inbetween. For example my commute to work and back every day consists of about 22 miles of dual carriageway with a couple of roundabouts and about 5 miles of driving through a town to get home.

I have tried employing some 'hypermiling' techniques. I rarely rev above 2500, I am very conscious of my light touch on the accelerator, i drive steadily, change up gear asap etc but still the mileage of about 40 mpg does not seem very good to me! What are the rest of you getting?

Here are some figures...

I have put £65 of petrol in the car since i got it. At £1.02 per litre this has given me 63.7 litres which is about 14 gallons. In that time, my car has done 568 miles. Doing the maths this comes out at 40mpg.

MNy previous car was a diesel, a 14 year old Peugeot 106 which of course easily did 65+ mpg. I had expected my new *petrol* car to do less but I didnt expect a much more modern and new engine to do quite as low as this, especially when Ford quote 50mpg for combined driving. I shudder to think what I would get if I did just drive aroudn cities all the time!

Any thoughts or have I just been spoilt by havign a diesel for the last 10 years?! :-)

Thanks
Melissa

40mpg isn't bad for a petrol engine really, but you should see more MPG out of it the more you drive it, and the more worn in the engine becomes. The quoted figures for cars are rarely attainable in the real world unfortunately.

If you want to work out what your MPG is exactly then I would use something like this:

http://www.torquecar...-calculator.php

Based on the figures you quoted you have done 40.54 MPG, or 11.44 pence per mile.

If your commute really is 22 miles of dual carriage way and 5 miles of town driving then your fuel bill for travelling to work will be roughly £710.42 per year give or take depending on how much holiday you get and how much petrol prices change. Scary stuff once you work it out!

You can compare your MPG here with another 90 Fiestas with same engine: http://www.spritmoni...1...&power_e=70

It`s in l/100km but you can easily calculate MPG....

My 1.4 is giving me 37-40 mpg (on the trip computer)

i think that you will find after you've got a few thousand miles under your belt the mpg will improve. i have the 1.6 petrol and if i behave i can easily get mid/high 40's on a long run.

How come after 14,000 miles I am lucky to get 41/42 even if I drive stupidly well, not breaking 60mph, hardly breaking or accelerating unless I have to?

My drive to work is 25 miles each way, all but 2 miles are dual carridge way or motorway!

Alot depends on the gradient of the road. If you travel on any hills or if there are lots of traffic lights causing you to stop start at either end of your journey perhaps?

On average on my 1.6 I'm getting 37 mpg. Mostly round town driving and dual carriageways, no motorways, only done 700 miles so far, and to be honest I'm quite pleased with it on petrol, its easily as good as my 1.4 MK6

[meddyliol]

I am getting 48 - 50 out of my 1.4 with about 360 miles on the clock.

[studly]

My previous mk7 1.25 was doing on average 40mpg with a total mileage of 2980 on the clock, but since i've had the 59reg 1.25 i'm only getting 36mpg but i've only done 387miles so far.
Hopefully it will get better after it's got some more miles on the clock.
My route to work is only 9.5miles but it's rural miles on cruddy lanes

Fantastic! But again, how does that work? When I have 13k on the clock and cant get over 42mpg even if I drive like a SAINT?!!!! on my 1.4 MK7?

Most of the Ford MPG assume you drive at about 55 mph lol

I'm on 37.1 mpg for about the same mileage and similar daily trip on B roads. Slowly creeping upwards and still some running in to do. Would probably be content with early to mid 40's mpg in the next few months.

I managed 50.2mpg once. but normally it tends to be around 37-40 ish.
