Mootoriõlide

Mootoriõlid are lubricating fluids designed to reduce friction, wear, and heat in internal combustion engines. They are composed of base oils and a complex additive package that enhances their performance properties. Base oils can be mineral, synthetic, or a blend of both. Mineral oils are derived from crude oil, while synthetic oils are chemically engineered for superior performance, offering better thermal stability, oxidation resistance, and low-temperature flow.

The primary function of mootoriõlid is to create a thin film between moving metal parts, preventing direct contact and the resulting wear. This lubrication also helps to cool engine components by carrying away heat generated during combustion. Furthermore, mootoriõlid clean the engine by suspending and transporting dirt and debris to the oil filter. They also protect against corrosion and rust by forming a barrier on metal surfaces.

The selection of the correct mootoriõli is crucial for engine longevity and performance. This is determined by factors such as engine design, operating conditions, and manufacturer recommendations, often specified by viscosity grades (e.g., 5W-30) and performance standards (e.g., API or ACEA classifications). Regular oil changes are essential to maintain the oil's lubricating and protective properties, as it degrades over time due to heat, oxidation, and contamination.
