My 41mpg is probably down to the easy trip to work and back, guessing mpg would drop in a city environment, etc . i really don't do short trips, so car up to temperature, all 50mph zones so can't push my luck ( all the time!) hope this helps explain my 41mpg checked last night 42.9mpg have been checking this by topping tank and it is accurate. Ps not being 25yrs old probably helps as well!
