Depends on where you are driving - City, Town, Country - I would make a guesstimate that 35 m.p.g. would be a good figure for fuel economy across all the types of area that I have indicated & should be easily achievable !
N.B. Good Driving is all about anticipation - e.g. Accelerating & Braking gently if you anticipate correctly what is going to happen in front / (behind) you will 'bump up' your Fuel Economy figures tremendously !
