Maintenance (filters, etc.)
A properly maintained vehicle will consume less fuel compared to one where maintenance has been neglected. A dirty air filter can increase fuel consumption by 25 %. Maintaining the thermostat and coolant in the engine ensures that the engine is always operating at its ultimate efficiency.

Tyre pressure
Correct tyre pressure is essential for safe and comfortable driving. Incorrect tyre pressure can cause erratic and dangerous behaviour during braking and cornering. Correct tyre pressure guarantees optimal tyre life and minimised fuel consumption. Tyre pressure 0.3 bar below correct pressure increases fuel consumption by up to 20 % due to increased rolling resistance.

Load/load distribution
Overloading a vehicle increases wear and tear of suspension, brakes, etc. Also the stability of the vehicle will be affected in a negative (dangerous) way. Don’t carry equipment you don’t need. Make sure the weight is, as much as possible, equally divided over both axles. Keep heavy items as low as possible. Putting heavy (and bulky) items on a roof rack raises the centre of gravity with increased risk of rolling the vehicle. A roof rack can easily increase fuel consumption by 40% especially at speeds over 100 km/h. If you are not going to use a roof rack on a permanent basis then remove it from your vehicle.

Air-conditioning versus windows wound down.
A comfortable temperature inside the vehicle is around 23-24 degrees Celsius. At speeds below 60 km/h often simply winding down the window will suffice. Over 60 km/h wound down windows cause extra drag resulting in increased fuel consumption and noise. Switching on the Air conditioning is then the better option.

Maintaining distance.
Maintaining sufficient (2-seconds rule) distance in traffic allows for anticipation and increased safety margin in case of an accident or an emergency stop. This leads to a “smoother” way of driving with less acceleration and braking. Less wear, less stress and reduced fuel consumption.
