Hi all,

I'm thing of getting a focus, currently I'm not doing many miles at the moment but in the near future I may be traveling around trip of 50 mile a day to work.

Now considering the price difference of diesel over petrol (of about 5p) will the diesel car cheaper car to run over a year?

Thanks
 
Most deisels of that size (focus size) will easily be doing around 45 / 50 mpg if not driven to hard.

Petrol your probably going to get around 35 at a push, if driven hard lets say 30mpg...

I regret buying a petrol modeo, it eats petrol at an astonishing rate when driven hard. The book says around 29 mpg..... I have to travel 82 miles a day round trip... it costs £10 a day.



You'll save sufficent over a year m8
 
ok

So what i'm really asking is:

How many miles before paying the extra for the car and the fuel before the car is cheaper to run than the petrol version (if that makes sense)

Isn't this the ultimate question?

Suppose on identical cars driven in the same way over average mileages you might save several hundred quid a year buying a diesel, if that...
 
Thanks Neal, a good 'real world answer' as i had not considered about how my driving style(s) would effect the cars mpg.

Thanks everyone for answer.

What? So you've had one answer with no facts, no calculations and nothing beyond flawed opinion and you want to close the thread?

Yes lets compare the MPG of a diesel not driven hard with a petrol driven hard :confused:

did you actually read what i said,

Not driven hard deisel focus will get around 45 - 50mpg

Not driven hard a petrol focus will get around 35 mpg.

Driven hard I said about 30 mpg on the petrol.

sorry to say, deisels is the better option for cost effective driving, compared to the same car in petrol.

Then i mentioned my car (mondeo 1.8 zetec) and its abysmall petrol consuption... at around 29 mpg...

whats so flawed about that?

Jees..... were not all rich IT bods you know.
 
29MPG abysmall, i'd never see that even when doing 40mph at 1000rpm in top :p

29 really isnt bad if you drive it with a fairly heavy foot, you wont save much by going to a diesel, factor in the costs of increased service intervals and the prospect of the more complicated turbodiesel engine failures.

from my old 1.8 zetec focus i got between 36-38 which was a 50-50 combination of motorway and town. I didn't exactly hold back.....on a motorway run you can get 40.

My friend has the 1.8 diesel and drives it very hard. He gets around 40 miles to the tank more. Driving steady should see you get 100miles more from a tank.
 
So lets do some maths on your figures based on average mileage of 10k a year, your 35mpg figure for a petrol Focus and 50mpg for a diesel Focus.

Petrol @ 104.9 @ 35mpg = £1360
Diesel @ 111.9 @ 50mpg = £1009

Saving = £350 a year

A diesel car will usually cost £1-2k more, used, than its petrol equivilent and provided you keep it 3 years, wont make you £1-2k more back at resale time.

Worth it for less than £7 a week saving?

Thats before we consider that virtually every commonrail turbodiesel WILL require a turbocharger replacement @ £1k at some point in its life. 3 years fuel savings wiped out on that alone..

Er, that's 38mpg, which is very economical for a petrol.

err but the diesel costs more per litre, AND the car costs more to buy and maintain..

its not as clear cut as just the MPG...


you would have to do 20-30k a year to make it worth while.

Lol, 29 mpg is abysmal when you earn **** all! lol

yes but were on about a low milage car, a modern deisel engine is only just run in at 100k nower days lol. Turbo'd deisel engines dont fail as often as your implying, unless ragged all the time.

My mates got a passat 1.9 tdi, with 189,000 onthe clocks, usual service intervals, are around the same milage as many a petrol engine.

My other friend has a Bora 1.9 tdi, and does the same milage as me a week, and his fuel bill is far less.... around £15 a week less.

Im not arguing, but a lot of you guys on here have big pay checks and big fancy cars, were not all rich you know. £15 a week would make a big diff to me a week, sad I know.

But you can afford the extra ~£3000 in the long run, based on Fox's figures?

How can you use the amount of money people in this thread earn as a justification for ignoring they're advice when they are trying to save the OP money?
