GENERAL INFORMATION

Viscosity of oil

Viscosity characterizes oil fluidity. Depending on temperature oil tends to reduction of fluidity. In process of increase in temperature oil becomes more fluid. It worsens ability of oil to stickiness and stability to maintain high contact pressures. When cooling oil gets denser, fluidity decreases and internal friction increases. Because of this property it is necessary to apply engine oil with such viscosity which changes at change of temperature in perhaps smaller limits.

The fluidity of oil is equivalent to its internal friction and is designated by SAE units (Society of Automotive Engineers – Association of Automobile Engineers), for example SAE 30, SAE 10. The high rate of SAE means that oil dense, low – characterizes liquid oil. Nevertheless, viscosity of oil completely does not characterize lubricant properties of oil.

ALL-WEATHER OILS

In engines of cars it is preferable to use all-weather oils. They are made on the basis of liquid one-seasonal oil (type 10W). In a heated state this oil is stabilized by a so-called thickener that provides the corresponding lubricant qualities of oil at all temperatures. When using all-weather oil, it is necessary to apply grades with a wide temperature range of viscosity, for example 10W-40, 15W-50.

The letter W (winter – winter) in the designation SAE characterizes suitability of use of oil during the winter period.

OIL WITH THE INCREASED LUBRICANT PROPERTIES

Oils with the increased lubricant properties represent all-weather oils in which, besides other additives, there are substances reducing friction coefficient that provides reduction of fuel consumption by 2%. By their production special initial components (synthetic oils) are used. Upon purchase of such oil it is necessary to pay attention to that this oil was allowed for use by Ford.

Prevention

Additional additives to oil, irrespective of their look and appointment, should not be added to oil.


For modern engines it is necessary to use only HD oils. HD oils are oils with the increased lubricant properties improved at the expense of various additives. These additives provide the best anticorrosive protection, more favorable conditions against the oxidation phenomenon, the smallest tendency to formation of slags, the best change of viscosity clearing and dissolving properties. The clearing and dissolving additives not only reduce formation of the remains in the engine, but also at the same time these remains and all other pollution in engine oil have ability to dissolve and keep in suspension so that when replacing oil these pollution are removed together with the merged oil.

Quality of HD oils is determined by the API system (American Petroleum Institut). The European producers also adhere to this system.

Designation of a grade of oil is made by two letters. The first letter characterizes a scope: S-Servise, are intended for carburetor engines; With – Commercial, are intended for diesel engines. The second letter defines an oil grade in alphabetical order.

Premium oils on classification of API are SG for carburetor engines and CD for diesel engines.
