I'm getting nowhere near 300 now as I'm only rarely doing journeys of more than 10 miles, most are only 3-4. Did a long motorway stint at the 1st fillup this month and was getting 45mpg but it's dropped drastically since then. The most difficult thing I find is that once the fuel gauge hits the top of the red reserve section it doesn't move so I've got no way of telling how much reserve there is, although I've never put more that 40 litres of fuel in. Makes it really hard to eke a tank out. Anyone else find the gauge doesn't move from the top of the red?
