To go with the fuel economy thread, what are people's tips for driving economically?
Some ones I can think of:
1) Keep your tyres inflated correctly - rolling resistance is a major drag factor at lower speeds. Note it doesn't go away at higher speeds, air resistance just becomes much bigger.
2) Braking wastes energy. Lots of it. You get that energy back if you brake less by stopping accelerating sooner, and not having to accelerate afterwards. Anticipate corners and back off early, driving smoothly through them.
3) Don't carry more than you need to in the car. If you don't need that oil or toolkit on *every* journey, take it out and put it back when you think you'll need it.
4) Keep the speed down. I can't remember the figures, but driving at 80 compared to 70 uses a significantly higher amount of fuel - air resistance increases proportional to the square of your speed. Unless it's unsafe to do so, don't be too rigid about your speed - using more fuel to stick at 70 rigidly up a hill then having to brake on the way down isn't smart. If you're not in a rush and can do so without holding people up try dropping to 60 on dual carriage ways.
5) Use gears! Making the engine labour at low revs isn't always economic, but once you're at the desired speed change into a higher gear. You can still enjoy acceleration (within reason!) without it having too much of an effect on economy.
6) Car share Okay, slightly cheating here, but while carrying another passenger is a lot of weight, it's still far more efficient to do one journey in place of two.
Any others?
