Cold starting
Frequent cold starting will not enable the engine to reach optimal running temperature. It follows, therefore, that consumption will be higher (from +15 to +30% in towns) as will the production of toxic emissions.
Traffic situations and road conditions
Heavy traffic and higher consumption are synonymous: for example, when driving slowly with frequent use of lower gears or in towns where there are numerous traffic lights.
Also twisting roads, mountain roads and rough road surfaces pay a heavy toll on consumption.
Traffic hold-ups
During prolonged stops (traffic lights, level crossings, etc.) the engine should be switched off.
