My MV6 is using alot of fuel. its running ok but drinking for the olympics. how can i fix this or is it a garage job.
thanks for all responses.
-
Back to basics. Last service? Was it actually serviced (not all garages are honest ;)).
In particular, I'd look at air filter condition and plug condition.
This time of year, it will use a bit more, very noticible if you do a lot of short journeys.
-
The car hasn't had a good service for a long time. Its mainly used for small journeys as my wife's elite estate is sat up ill.
Will check on the basics this weekend then get it properly serviced.
Hopefully that will increase the mpg.
-
Oil change and Air filter to start with. then change the oil again after 500 miles if it hasnt been changed for years. So long as your brakes arnt binding ect id start there. Cheap to do also :)
-
What size engine and how many mpg?
-
Agree with all above. Also, since it's free and easy to check, it the temperature getting up to mid-scale (90ish)?
-
Multi rams working, blocked exhaust?
-
The engine is the 2.6
Had a stainless system fitted with a 3" out and that is black inside from excessive fuel
Don't know the mpg - scared to find out.
I used to have a 3litre elite which on a run was getting 35+ but even with good sensible driving this can't reach that.
-
if you were averaging 25mpg id say that was average but 35mpg is quite something. Does it feel down on power?

Don't all Omegas have a trip computer? :-\ :-\

Not mine, Thankgod ;D

A V6 is never going to get 30+mpg when knocking about town ......... ;)
-

35mpg on a decent run is perfectly achievable from a 3.0l. Don't think DBW will achieve that. Obviously, around town, that plummets like a stone, or if you hoof it...
-
Yes this has a trip computer but never actually took any notice till now especially since the wife has started using MY CAR...
I should be getting slightly better than the norm as i have has both middle boxes replaced for a single box. it increases power but when taken steady also increases mpg.

Mine is over serviced and best i can get is 30mpg which i have averaged for a while now due to mainly long journeys.
-
I agree with the majority... It's likely to be standard servicing, tyres, plugs, air filter, oil & breathers. Even if none of these look drastically bad, improving them all together should make a difference of some sorts.
Other things to check are the timing/mixture. Engine temperature is a good point, a warm engine is an efficient engine as my ol' man used to say :P
If they throw up nothing then you'll have to do a bit more digging... brakes binding and other stranger things.
Only other thing I would add is bear in mind you can loose about 6mpg in the cold weather! And with a V6 I would 25mpg was a very acceptable figure. My 2.5 Auto used to dip to 18mpg unless I was meticulously careful

cheers

In 8 yrs I've seen similar from mine once, but that was on an empty motorway at a very steady 75 (in cruise) Even on a trip to Edinburgh & back last week my average mpg only got as far as 30-ish
-
makes me think i should have kept the 3ltr :P

Has it dropped since exhaust fitted? Its not uncommon for 'performance' exhausts to bugger up performance, economy or both.
-
My 2.5 V6 has recently been serviced, runs like a dream (touch wood) but still get about 20mpg around town.

Can't see why a single box should make any improvements to mpg. :-\ :-\
If it does improve bhp as you say, that bhp doesn't come from nothing, it needs to take its energy from somewhere ie use more fuel AIMHO ;) ;)

Yup, a 70mph constant cruise, not using cruise control (its a bit basic on on DBW), can return good results. UK roads often preclude it, as you always get some tit pulling out in front of you.
But it is perfectly possible ;)

Autos around town are hopeless for mpg
-
true. but i had the exhaust planned and hand made so yes when u want the power its there at the cost of fuel but for normal driving it sets up better mpg - well it would do

Definitely! If I was of sound mind I should have a Eurobox as most of the driving I/we do is town. But hey I'm a nut case so it is cool! :y

Do you still have the old exhaust so you can compare mpg's I think you might have 'found' your lost mpg's ;)
-
no - old one replaced for new one
-
does anyone know a good garage for a proper service in south wales
-
no - old one replaced for new one
I had my tongue in my cheek ;) ;)
-
sounds painfull !!!!!!!!!!

As long as you didn't have your tongue up someone else's cheek :P
-
yuck. :o
-
i did a run from kettering to ormesby nr gt yarmouth last weekend and averaged 29.9 mpg ad that wasnt taking it easy and also using kick down a fair bit for overtkaking ;D

I'ts alwats best to leave it set on outside temperature anyway :)
