The oil expense The engine oil part burns down during lubricant action. So the oil expense is absolutely natural process. Well обкатанные engines spend 0,2 l for 1000 km, Audi names as much as possible admissible indicator the expense of 1,0 l on 1000 km.
The zero expense of oil is suspicious At winter operation on short distances can be and so that oil level between measurements is not diminished at all or even increases. It at all an occasion to pleasure because means that engine oil is diluted with fuel or a condensate. This oil changing the property is necessary for "boiling" during regular distant trips that the condensate has evaporated. In the end of a trip it is necessary to check up oil level because it considerably will fall because of evaporation of parts of gasoline and a condensate! At extreme operation in a city without intermediate trips on a long distance it will be better, if you change oil before the usual; probably, already after 3000 km or four months. The correct specification of oil As at rather long, 15 000 km, intervals of replacement of oil there is a danger of formation of a deposit in oil картере, Audi has let out strict instructions to oil.
Viscosity of oil Fluidity of oil, that is its viscosity, should correspond to requirements for application in the given engine. Thus it is necessary to remember two criteria:
Classes on SAE American Society of Automotive Engineers has distributed oils on classes according to their viscosity. Seasonal oil These classes begin at engine oils with liquid winter (winter) oils SAE 5W, 10W, 15W through intermediate step SAE 20W/20 to viscous summer oils SAE 30, 40 and 50. All-weather oil Manufacture of all-weather oil applied today is more difficult, and consequently all-weather oil accordingly more expensive, than seasonal. As an additive improving an index of viscosity, at it there are long chains of molecules which "inflate" at heating and again lose in volume at cooling. In this case oil can "elastically adapt to temperatures and cover many classes of viscosity. Oil SAE 15W-50 corresponds at temperature in–15C to a viscosity class 15W, and at 100C – to a class 50. |
