Fuel Economey..........

[raceboy]

Recently the amount of miles between fill ups seems to getting be smaller and smaller, I've not done the maths yet I'll work that out between the next to fill ups but any ideas as to what could be causing a reduction in 'economey'?
I've had a poke around and can't see anything obvious amiss, the stepper motors had a clean and it's still running the same as it ever has it just seems the petol gauge has a magnetic draw to the left, and no there aren't any petroly puddles under the car in the morning

Had the thing nearly 4 years now and I can't say I'm driving it any different to how I was 6 weeks ago,

It better not be the lambda's again, had them changed about a two years ago, when they went last time it was kicking out huge clouds of black smoke and I've not got that this time

Consistant petrol brand for the last 6 months (Esso) but different stations, funnily enough my car is the 0.01% that hates Optimax I get about 5mpg on the stuff and it runs like a bag of nails
Like the earth expansion idea the best so far
