Well guys, on the trip down to Norfolk, and a bit of running around, I had done 350 miles before needing to fill up.. I only managed to get 48 ltrs in it... that works out at over 33 to the gallon... in theory, with 12 ltrs left, I could have squeezed another 80 miles out of her, at that rate, I could have got 430 miles on a tank..
normally, I get about 220 before I have to fill it. just shows what having gertie at the side of me can do
