2.1.8.2. All-weather oils

GENERAL INFORMATION

In engines of cars it is preferable to use all-weather oils. Advantage of all-weather oils consists that it is not necessary to choose them seasonally. They are made on the basis of liquid one-seasonal oil (type 10W). In a warm condition 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 modern grades with a wide temperature range of viscosity, for example, 10W-40, 15W-50.

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