System of greasing of the engine
All-weather oils should be applied to BMW engines. Advantages of all-weather oil consists in possibility of its application without replacement as in the summer and in the winter. A basis of all-weather oil is liquid seasonal oil (for example 15W). By means of so-called thickeners oil is stabilized in a hot condition, keeping thus lubricant properties under any service conditions.
The letter "W" in designation of SAE indicates the oil suitable for operation in the winter.
Scope viscosity oil / class
Scopes of the next classes SAE have the general sites that allows existence of short-term deviations of temperature. Mixing of oils of various classes of viscosity if, for example, it is necessary to add oil which viscosity is allowed does not correspond to a class of viscosity of the oil being in the engine.
Introduction of lubricant additives of any kind in fuel or oils is not allowed.
Specification of impellent oil
Modern impellent oils contain the alloying additives which are essentially improving them of property. These additives increase corrosion firmness of oil and its firmness in relation to oxidation, reduce a shlamoobrazovaniye in an oil case, increase vyazkostny, clearing and dissolving properties of oil. Clearing and dissolving additives not only reduce formation of a precipitation in the engine, but also possess at the same time property to dissolve and crush them and other pollution in impellent oil and to support them in a suspension so that pollution were removed at oil removal.
Quality of impellent oil is characterized by norms of the manufacturer of the car and oil.
Classification of impellent oils by the American manufacturers is carried out on API system (to API: American Petroleum Institute). Designation consists of two letters. The first letter indicates a scope: S-Service, is intended for petrol engines; C-Commercial, is intended for diesel engines. The second letter indicates quality in alphabetical order. SH API specification oils for petrol engines and CE for diesel engines have the first-rate quality.
The European manufacturers of oils have the CCMC specification. They are made taking into account the European production technology of engines. Oils for petrol engines depending on quality have classes from CCMC-G1 to - G5. Diesel oils for cars have the CCMC-PD1 specifications, the first-rate quality of CCMC-PD2.
The European manufacturers in addition specify still the CCMC specification. The CCMC specification considers, in particular, the European manufacturing techniques of engines. Oils for petrol engines depending on quality receive the classes G4 and G5. Diesel impellent oils for cars are available in the CCMC-PD1 specifications and in the specification of more quality CCMC-PD2.
The European commission of CCMC was replaced with “ACEA” (Association des Constructeurs Europeems die l’Automobile) which continues to develop test methods and quality classification. Oils for petrol engines of cars depending on quality have classes from ACEA A1-96 to A3-96. Oils for diesel engines have classes from B1-96 to B3-96.
Consumption of oil
The consumption of oil of an internal combustion engine considered its consumption owing to combustion process. The consumption of oil should not be confused to its leaks arising owing to a leakage of the pallet of a case, a cover of a head of cylinders etc.
The normal consumption of oil is a consequence of combustion of its some quantity in cylinders, losses together with the fulfilled gases and friction products. Besides, oil is spent owing to high temperatures and the pressure, arising in the course of combustion. The consumption of oil is influenced also by service conditions of the car and admissions of manufacturing of separate details. Under normal conditions operation the consumption of oil is so insignificant that between planned intervals of replacement of oil its insignificant addition is required only. The normal consumption of oil makes 1.5/1000 km.
Oil is necessary for adding, if “Nachfull” mark (the amount of added oil in this case makes 1 l) is reached.
