The oil consumption of the engine at long distances must be calculated in advance. At first, it may exceed the given values. Frequent trips at high speeds lead to an increase in oil consumption.
The oil consumption in the engine, depending on the type of journey, is a maximum of 1.5/1000 km.
Driving at very low outside temperatures, at frequent traffic lights, with a trailer and in the mountains increase fuel consumption.
When installing additional devices (e.g. air conditioner) fuel consumption increases very little.
