The oil expense Engine oil part, carrying out the functions, thus burns down. Thus, the oil expense represents absolutely natural process. Well adjusted engines spend 0,2 l of oil for each 1000 km. Audi names in as much as possible admissible size the expense of greasing of 1,0 l on each 1000 km. That, how many oil spends yours Audi A4, depends on following circumstances: The excessive quantity of oil conducts to it большему to the expense because through ventilation картера surplus of oil is blown in the engine; Liquid oil burns down faster, than dense. Seasonal oil in нагретом a condition becomes liquid as water, and its expense accordingly raises. All-weather oil remains dense; it involves its smaller expense – especially it considerably at long trips; The all-weather oil too long remaining in the engine, is slightly diluted, losing the higher class of viscosity, and the requirement for its additive accordingly raises. The sharp manner of driving on high turns of the engine, except increase of the expense of fuel, increases also the oil expense. It is especially brightly shown, when the new engine starts to work at once with full loading. In time обкатки it is necessary for the engine of a bit more greasing, than usually. негерметичность . Check up everything as it is described in the head Engines . Defect in the engine; for example, defect of linings of a core of the valve, is too great a backlash 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 deterioration or the tease of the piston. Absence of the expense of oil it is suspicious In the winter, at driving on small distances, happens so that level of oil from gauging to gauging does not decrease, and even raises. The bases for pleasure here are not present any as it means that engine oil разжижено fuel or a water condensate. These "additives" considerably worsening lubricant qualities of oil, it is necessary to "boil down" by regular long driving that the condensate has evaporated. Then it is necessary to measure at once oil level as after evaporation got to gasoline or water oil its level will sharply go down! At driving it is exclusive in an extreme city mode without intermediate trips on a long distance it is recommended to change oil more often, than through the intervals specified above, for example through each 3000 km of run or time in four months.
