Prior to getting my Meega, I had (no guffaws please) a Citroen Xsara 1.9 turbo diesel estate - sh*t car but reliable and good fuel economy of approx. 45mpg.
Since I got the Omega which only averages 25-26mpg, the price of bloody fuel hasn't stopped going up, and I read in today's paper that fuel prices are set to reach a new high due to the bloody idiots in the Middle East that never stop knocking two tons of sh*t out of each other
However, I found a website called petrolprices.com. Enter your post code and it will tell you where the cheapest fuel can be found in your area....how cool's that 8-) I admit that there's usually only a few pence per litre difference, but every penny counts as far as I'm concerned!
