At last, a long distance opportunity to check our 2019 Peugeot 1.2 puretech EAT6 130 computer accuracy - a holiday down to Cognac, mainly motorways (smooth clear French ones, bumpy crowded English ones) with a bit of local driving during our stay.
Starting mileage approx 13,500, so front tyres (presumably providing the info) approx half worn. SWMBO drives cautiously and slowly, so long term computer no. 1 currently reads 6214 miles, 42.7mpg, 32 avr.mph. I drove quickly but economically (cruise control no faster than 75mph even on the 130kph stretches). On return from this 'brim to brim' trip, computer no. 2 reads 1377 miles, 47.0mpg, 48 avr. mph.
Actual (E10) fuel used (Tesco, E Leclerc and Intermarche supermarkets) was 137.90 litres which gave a true figure of 45.4 mpg, so the computer is roughly 3% out. The long distance ensures that a large error of plus or minus 3 litres is needed to alter that by only plus or minus 1mpg. Incidentally, price ranged from 199.9 to 208.9 euros/l., much the same as UK.
I hope this might amuse some fellow geeks and wonder if anyone else has checked their computer for optimism/pessimism?
