[YZ250]

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?   

Isn't that a 30 limit, with the cash machine safety partnership van in the farm gateway by the sign?

Err yes, that's the one.  A 30 going in to a 60 but I may be guilty of starting my overtakes a little early.  hence the ticket

Cid reckons 437 miles from a full tank...

We shall see

Won't be disappointed with 280-300

That's incredible, I'm going to have to take a longer route to work just to improve my mpg. 

[05omegav6]

To be clear, I filled it post MoT, drove it 11 miles home and disconnected the battery to change the alternator.

437 is what it was saying when I got in it this evening to go shopping. A mile and a half later and it's down to 431

A buggered stat would explain why she returns decent enough fuel economy on a run, but round town, straight after startup, she's derisory 

Accept its a heavy tank with a big engine and no direct drive from engine to wheels under 50mph.

Your readings sound perfectly normal.

Not to me, if mine was that bad there would be no reason not to have either the Interceptor or V12 Jag  I've always fancied. And some modern tech on each of those would make worthwhile improvements for a daily driver.

Short urban trips from a 2.5 auto?  I'd be happy with 15mpg

I've had the magical 500m from a tank of petrol in the MV6

Was it on a flatbed recovery truck though, as I think you'll find that doesn't count.

500 metres that's impressive

I used to get better than that out of my old twin turbo 300ZX!

Then again I don't drive everywhere like I'm on the starting grid of Monaco, so..

The important thing to remember is, werer all getting fatter as we get older. So mpg will drop because more weight to be pulled along

See this was my issue - if I'm really doing that kind of mpg, then why don't I get the XK8 / R I've wanted for years? Also Interceptor or a lovely old XJ12 sounds like fine choices. Christ, a Hummer wouldn't be far off that figure (not that I'd ever want one) Ten minute drive today, gauge read about 87, just off the bottom, really. Generally she sits at 90ish. Which I've always put down to a poor gauge, knowing how 'approximate' they are. However, a new stat isn't going to hurt anything.

The Dorset Racing Snake might have a point aside from being a touch tall Sir Tigger would make a passable jockey

Im a supple and lithe 17.5 stone... if I borrow MrsGKs 1.0 Lupo you can hear the engine and springs go 'are you taking the mick?!'

When I had my XJ[a 3.2 auto] on the road I once disconnected battery-forget why- when re-connected and car used for short urban trips computer showed average consumption at 11.4 to the gallon.Would imagine an XJ12 even in HE form would struggle to better it.

That was a different holiday

Nope, genuine 500m from tank on the way down to Montpellier.  Actually managed an average of 32.5mpg over the 1800m holiday
