Consumption of oil The part of engine oil burns down during lubricant action. So the consumption of oil is absolutely natural process. Well rolled engines spend 0,2 l for 1000 km, Audi calls the most admissible indicator an expense of 1,0 l on 1000 km.
The zero consumption 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 a reason for pleasure because means that engine oil is diluted with fuel or condensate. This oil changing the properties is necessary for "boiling" during regular distant trips that condensate evaporated. At the end of a trip it is necessary to check oil level because it considerably will fall because of evaporation of parts of gasoline and condensate! At extreme operation in the city without intermediate trips on a long distance it will be better, if you change oil before the usual; probably, after 3000 km or four months. 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 an oil case, Audi issued strict instructions to oil.
Viscosity of oil Fluidity of oil, that is its viscosity, should correspond to requirements for application in this engine. Thus it is necessary to remember two criteria:
Classes on SAE The American Society of Automotive Engineers distributed oils on classes according to their viscosity. Seasonal oil These classes begin at engine oils with liquid winter (winter) of SAE 5W, 10W, 15W oil through an intermediate step of SAE 20W/20 to viscous summer SAE 30, 40 and 50 oils. All-weather oil Production of all-weather oil applied today is more difficult, and consequently all-weather oil respectively more expensive, than seasonal. As an additive improving an index of viscosity, at it there are long chains of molecules which "inflate" when heating and again lose in volume when cooling. In this case oil can "elastically" adapt to temperatures and cover many classes of viscosity. SAE 15W-50 oil corresponds at temperature in – 15°C to a viscosity class 15W, and at 100°C – to a class 50. |
