I did a couple of 140 mile runs recently and got 45 mpg overall both times. This was mostly motorway with about 20 miles of rural roads at the end of the journey. On the motorway stretch at 70 mph with PA2 on I got over 47 mpg. My long term consumption is 33.3 mpg but I do make lots of short journeys normally (although I do have the aux heater to pre-heat the engine which helps).

35 mpg on the highway doesn't seem right, especially as you are (presumably) driving in warmer conditions.
