1. Anticipate Traffic Flow
Read the road as far ahead as possible and anticipate the flow of traffic. Act instead of react – increase your scope of action with an appropriate distance between vehicles to use momentum (an increased safety distance equivalent of about 3 seconds to the car in front optimises the options to balance speed fluctuations in traffic flow – enabling steady driving with constant speed).
2. Maintain a steady speed at low RPM
Drive smoothly, using the highest possible gear at low RPM.
3. Shift up early
Shift to higher gear at approximately 2.000 RPM.
Consider the traffic situation, safety needs and vehicle specifics.
4. Check tyre pressures frequently at least once a month and before driving at high speed
Keep tyres properly inflated as low tyre pressure is a safety risk and wastes fuel. For correct tyre pressure (acc. To loading, highest pressure and speed driven), check with car’s manual.
5. Consider any extra energy required costs fuel and money
Use air conditioning and electrical equipment wisely and switch it off if not needed. Electrical energy is converted from extra fuel burnt in a combustion engine, so electrical equipment doesn’t work “for free” – it always costs extra energy and money.
Avoid dead weight and aerodynamic drag.
