• Drive a smaller (diesel) car, especially if you commute long distances (> 20 miles).
• Remove the alloy wheels from your car, honestly, this is a big saver, use smaller rims instead, the car will move more easily with these, they don’t look the part beside alloy wheels, but this change alone could increase your fuel efficiency by 25%, depending on how you drive.
• Change gear earlier, drive smoother.  When others told me about this, I often thought that I do drive smooth already.  I think the key to driving smoother is to make sure that the car changes gear earlier, say for example at 2000rpm instead of 3000rpm so the car isn’t working as hard, the key here is that because the hdi engine uses technology (not unlike a turbo) to produce more lift when you reach > 2000rpm, changing gear before this magical figure will reduce the amount of fuel being burned.
• Like the previous tip, keep your rpms to below 2000, especially true of you drive a diesel car, except when in your highest gear.
• When coming to a stop (at traffic lights for example), drop out of gear, coast to the lights.  If the lights change, don’t forget to change back into gear again!  I wouldn’t advise coasting at other times though.
• Don’t over-take.

At times when trying to do all of the above, it might seem like it takes forever to get anywhere, people might beep at you, or even over-take aggressively, but guess who’ll be laughing at the end of the week!
