2.5V6 Questions

[Paj]

Hi,

I am looking at purchasing a 2.5 v6 manual saloon. What is the mpg like on these, Parkers says 31. Any major things to look out for when testing?

Cheers

[Paul Beazer]

All the usual things, service history, proof of mileage, cambelt changed (every 54k miles). Also make sure if its a manual that the gearbox isnt noisy, they have a habit of getting a bit noisy if they're getting on a bit (usually the input / output bearings, approx £500-800 to be fixed). If its an auto make sure it shifts smoothly. The tappets on the engine can be a bit noisy, but usually an oil change and flush will sort that.
MPG can vary from 25-33, depends on how you drive it really.
Welcome to the club and may i congratulate you on your choice!

Cheers for the info. Anyone else got input as to mpg as thats the major thing putting me off atm, currently drive a 2.0 Mondeo that gets from 29mpg in town to 45 at 60 on motorway. will join the club if I do get one :)

I used to get low 30's on the motorway, but not at 60 ;) and high 20's around town. The V6 is very frugal for a 2.5l engine, but also torquey, smooth and refined. I would buy one over a 2.0 every day of the week, for the 2-3 mpg difference it makes!

I took my car up to bham from london over the weekend just gone. I was surprised by the mpg I got, it was really good. I use to have a 1.5 civic before and obviously the mpg on that was way better but I gave up the mpg for the v6 and never looked back! What you lose mpg wise (which wont more then 3mpg) on the 2.0 Mondeo, is not even worth thinking about mate!

35+MPG IS POSSIBLE ON The motorway, I averaged 32mpg on mine, it was thrashed everywhere too

[pitslayer]

37mpg can be had out of them, well got that out of mine, and was in fairly heavy traffic on dartford crossing so that was pretty good, full tank to empty

take your time and run on super (99 ron) and it may shock you up to 38mpg, however how do you stay at 60mph :zzz: top cars v6's

You're right with the 60mph bit.

Once you hear the engine tone change, fuel economy disappears up the swannee!!!!!!
I've started driving in deep sea diver's boots in case common sense starts to override aural pleasure:evilgrin: :evilgrin: :evilgrin:

Can't get my head round the"I really want a 2.5V6 but I'm worried about the fuel economy" brigade...
If your budget is so tight that a few mpg is the deciding factor then you are really shopping in the wrong market aren't you?????

Don't mean to offend anyone with these comments by the way.

i have managed 39mpg a couple of times on a cross country journey , but that was when times were a bit tighter , now its back to 10-15 quid a week , and i only use it twice a week ;)

I always thought the faster you drive, the more fuel the car consumes?

Does town/city driving generally consume more fuel then motorway/dualcarriageway driving?

[psbarham]

as long as the speed is constant the mpg will be good , its the stop/start round town that kills it .

[I-S]

The thing that wastes the most fuel is the brakes. Every joule of energy converted to heat in the brakes came from motion. With the overall thermal efficiency of engine and driveline, etc, that means that you burned 4 joules of fuel to warm up your brakes.

Typically a car will be most efficient cruising at a constant 55-60mph. Above that there's more rolling resistance and aerodynamic drag to overcome, below that you're not running as optimally efficient gearing (to high a gear uses more fuel as much as too low a gear. 2000-3000rpm is optimal).

Stop/start in town is horrific on fuel.

I can do the boring "how to save fuel safely and still drive reasonably fast" if you want, but most people aren't interested.

go on, Im interested................:)

[pitslayer]

called dont boot it to the speed limit and stick the thing on that ivejust forgotten the name off.....the the thing that keeps you at a constant speed...cruise control thats the bugger lol


and i agree with the its hard to keep the aural pleasure to a min, love the noise thatV6 makes just pure sex

[I-S]

Actually cruise uses more fuel.

I will post a long and boring thread at some point when I have time and inclination.

[Kieran]

Actually cruise uses more fuel.

Really?:speechles I guess it depends on the driver - It was always more economical for me to use it in my GLS.

[ritch_w]

on Top Gear Clarkson drove from london to Edinburgh and back on 1 tank of diesel in an Audi TDi (A6 twin turbo diesel????)

Anyway he reported he was using more fuel using cruis and soon ditched it.
He just made it back to the forecourt where he originally started / filled up.

I found it used a little less fuel on fairly flat roads, but more on hilly ones like the M62...

Still the one thing I really miss with my current car not having it /pan

It was an A8 4.0 TDI V8. I'll write the new thread...

thats the one! Its on UKTV Gold every 2 weeks!

[pitslayer]

i found on flat roads aswell cruise uses a lot less, then at hills i turn it off and use my foot. so far get 37mpg.....unless im nailing it to work when im late, which is usually most days, then i just watch the fuel gauge go down lol

[Exbury]

As per my other thread I used to get 32mpg (average) out of a 2.5 V6 Estate and 33mpg (average) out of a 2.0 GLS saloon.

My friend bought a 1.2 punto, she gets a fantastic 40mpg out of it or so, unfortuantely paying out £1500+ for 3 head gaskets, etc in the last years etc etc. Me (apart from latest problem) has shelled out £200 or so in extra bits over 2 years of owning Galants. Admittedly the gearbox is a problem, but then I have 166k miles on mine!

what kinda problem is ur gearbox giving?

[Exbury]

It was grinding when i bought it and gave out 15k hard miles later. however the gearbox itself is fine, its just the bearings are really shot and leaking oil into the bell housing and onto the clutch!
