Oil consumption

Part of engine oil, performing the functions, at the same time 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 lubricant on each 1000 km. That how many oils are spent by 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 increase in fuel consumption, increases also an oil consumption. It is especially brightly shown when the new engine begins to work with full loading at once.
  • during a running in the engine needs a little more lubricant, 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 big a gap between a guide of the valve and a core of the valve, 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, when driving on small distances, happens so that oil level from measurement to measurement does not decrease, and even raises. There are no reasons for joy 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 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! When 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 a run or times in four months.

It is necessary to take into consideration an oil consumption in 2–3% in the winter, at the same time 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.
