Musings on fuel economy...
« on: 30 November 2015, 16:58:41 »

So... given I'm not going to get anything from the Insurance company any time soon, I've started to look at less high priority jobs, which nonetheless are issues.

One of which being - dreaded low fuel economy. Just wondering what the main culprits would be. At present, admittedly town only driving, and often a 5-10 minute journey to work the engine isn't even at 90oC. Worst I've managed as little as 58 miles from £25, which works out at a 'funny if it weren't so tragic' 11mpg.... realistically I don't seem to go into three figures of miles from a given £25 fillup.

Wondering if something as simple as a fuel leak could be the cause.  :-\

Auto?  Sounds about right.

I've managed 15 miles from £20 before, approx. 5mpg.  But it was worth it.

Given fuel is under 55ppl (or 49ppl where she works), we're both suffering a spot of DILLIGAF.

At a guess, I'd say my poor economy was self inflicted.  :-X

Note to self:
Don't rise to tailgaters or get so annoyed by dawdlers.  ::)

Not helped by the fact the 3.2 is quite thirsty, unless driven in real miss daisy mode (which rules you out!)

I don't expect anything less than 420 miles from my £40 of LPG  :D

The 3.2 on the other hand  >:(

Getting 270-300 consistently from my manual 3.2... can't speak for the auto one as I don't think I have put three tanks of fuel in it since February  ::)

Getting 270-300 consistently from my manual 3.2 ..............

A while back, after a long motorway run, I filled up and definitely saw the range show 270.  :y
I never actually achieved 270, but it was definitely there on screen.  ::)  ;D

What am I doing wrong that prevents me achieving such figures.  :-\ ;) My journey home each day involves a long incline, which is where I tend to overtake dawdlers. Could it be this?   :-\ ::)

I blame your in-laws local council for that, for extending the zone too far.  ;D

This all makes me wonder what I'm doing wrong, as I've never had less than 300miles from a tankful, and the last 3 have given 400miles. It averages what my manual 525 used to do on a run.


It was still doing over 20mpg when the thermostat wasn't working.

£25 will take me 200 miles  :)

Not in the absolute comfort of a 15 year old omega, obviously.  ;D

Get you far further than that if you use your OAP discount on National Express...

Not an OAP, unlike most on here. And National Express only travel between different towns and cities. Don't wanna jump on one of them, might end up with the monkey hangers.

You know what this part of the world is like for roundabouts... and mine is either stuck in traffic or hammer down :-X
