Repair and operation of the car

Part of engine oil, carrying out the functions, thus burns down. Thus, the consumption of oil represents absolutely natural process. Well adjusted engines spend 0,2 l of oil for each 1000 km. Audi calls the most admissible size an expense of 1,0 l of greasing on each 1000 km. That, how many oil spends your Audi A4, depends on the following circumstances:

• the excessive amount of oil conducts to its bigger expense because through ventilation of a case surplus of oil is blown in the engine;
• liquid oil burns down quicker, than dense. Seasonal oil in a heated state becomes liquid as water, and its expense respectively raises. All-weather oil remains dense; it involves its smaller expense – especially it noticeable at long trips;
• the all-weather oil which is too long remaining in the engine is slightly diluted, losing the highest class of viscosity, and the need for its additive respectively increases.
• the sharp manner of driving on high turns of the engine, except fuel consumption increase, increases also an oil consumption. It is especially brightly shown when the new engine starts working at once with full loading.
• during a running in the engine needs a little more greasing, than usually.
• leakage. Check everything as it is described in the head Dvigateli.
• defect in the engine; for example, defect of laying of a core of the valve, is too great a gap between directing the valve and a valve core, defects of piston rings or their wrong installation at repair, damages of a wall of the cylinder owing to wear or the tease of the piston.

Lack of a consumption of oil it is suspicious

In the winter, at a driving on small distances, happens so that oil level from measurement to measurement does not decrease, and even increases. The bases for pleasure are not present here any as it means that engine oil is diluted by fuel or water condensate. These "additives" much worsening lubricant qualities of oil need to be "boiled down" by a regular long driving in order that condensate evaporated. Then it is necessary to measure at once the oil level as after evaporation got to oil of gasoline or water its level will sharply go down! At a driving only in the extreme city mode without intermediate trips it is recommended to change oil for a long distance more often than through the intervals stated above, for example through each 3000 km of run or times in four months.

It is necessary to take into consideration an oil consumption in 2–3% in the winter, thus our engines with injection contain in oil less gasoline at the dosed enrichment of working mix during start of the cold engine, than in old carburetor engines.
