I made a very broad estimation of my Ulster's consumption on a recent touring holiday using rough mileage (Google maps) and total of petrol receipts, assuming an average ~1.80/litre at the time. It came out at 47mpg, for a car with 1 1/4" SU and a fairly full load of camping gear. I covered long distances daily at a steady 35 - 45mph depending on the road conditions. If anything I'd say that was a conservative estimate.
