This originated with me sending regular emails to my close friends and family on environmental issues and changes which could ‘green’ their lifestyle. The group has unintentionally grown quickly as friends of friends ask to join. The EcoEmails don’t always give people an easy solution to a problem but try to make them aware that every decision they make has environmental and sustainability consequences. If you would like to join pls email me at

Car Efficiency July 17, 2008

To reduce rolling resistance:
Fill tires to their maximum inflation pressure- (the higher the pressure the less surface area in contact with the road and therefore the less resistance)
The negative side to this is to fill the tyres with too much air,and the life of the tyre will be reduced because it will wear out in the middle of the tread so you need a to check the recommended pressure
This will probably increase overall efficiency by about 5-10 percent

To reduce air resistance:
Roof racks on the car, this can effect the resistance a surprising amount so take them off when not in use
A shark fin low profile type aerial is more efficient than a stalk aerial. Taking these off will increase overall efficiency by probably 5%

Slow with gears:
Slow down with gears rather than breaks, because apparently modern IC engines use NO fuel when doing this this saves petrol

The slower you accelerate the less fuel you burn

Double your speed, you quadruple your drag due to air resistance
