OK the moment of truth is here. After selling an extremely thirsty vectra and replacing it with a 10 year old 1.7 dti astra estate - I have just filled up for the first time.
Its good news - the old girl has returned a very useful 52.18 MPG, exactly double what I was getting from the vec.
So the next step is a well earned oil change, pump the tyres up a bit more and remove everything from the interior that isn't essential. Watch this space for the next set of figures.
PS Mr Brown and Mr Darling will now have to wait that little bit longer between rip-off's (I mean fill-ups)
