Note this is for my car though with 16" wires and 205/55/R16 tyres. I believe yours has 15" rims and slightly taller 60% profile tyres so will be similar
I can give you the Excel file if you wish so you can insert your own revs/mile for greater accuracy.
ETA: FWIW your driving impressions concur perfectly with mine. Rarely use first and to expidite motorway overtaking you need to change down a gear or two as 70mph is only just over 2000rpm. 6th can give you 33 real mpg (remember the digital readout is US mpg) though.
