hmmmm... I am not entirely convinced that your increase in consumption is solely to do with the change from 19" to 20" setup. Exactly what size tyres are you running on your 20".s? Did you also re-check your wheel alignment when you upgraded? IMO I don’t think that the tyres should have made that significant a change to your consumption if you matched the correct circumference and have correct wheel alignment.
I also have Pirelli Scorpion ATR’s but I opted for an increased rolling circumference (for better ground clearance) and this has thrown my indicated consumption, as per the trip computer, out by 5%, but adjusting for that my consumption is much the same as before.
