My preference is for high-torque at low revs engines and trying to select a gear that keeps me below peak torque as far as possible; modern diesels seem to be so highly geared that you need to drop two gears to get any lift. My IAM observer advised holding 3rd gear in town at 30MPH (this was in my 240GLT) but would have been appalled had I been driving at 60MPH in 3rd since IPSGA is the basic mantra and the "G" stands for Gear - select the appropriate one for the circumstances. Accelerating from 60MPH in 3rd might have been acceptable.

It might be worth checking with your county council about road safety courses; Cheshire used to offer classroom-based ones with the opportunity to have your driving critiqued by a Police Driving Instructor during a 1-hour drive.
