moottoriöljy

Moottoriöljy, also known as engine oil, is a lubricant used to reduce friction and wear between moving parts in an internal combustion engine. It is typically a synthetic or mineral-based fluid that is formulated to meet specific performance requirements, such as viscosity, oxidation resistance, and wear protection. Engine oil plays a crucial role in maintaining the health and longevity of an engine by keeping its components clean and reducing heat buildup.

The primary function of moottoriöljy is to lubricate the engine's moving parts, such as the pistons, crankshaft, and bearings, by forming a protective film between them. This reduces friction and wear, which in turn helps to minimize energy loss and extend the engine's lifespan. Engine oil also helps to cool the engine by carrying away heat generated during combustion and dissipating it through the engine's cooling system.

There are two main types of engine oil: mineral-based and synthetic. Mineral-based oils are derived from crude oil and are less expensive than synthetic oils. However, they may not provide the same level of performance and protection, especially in high-temperature or high-mileage applications. Synthetic oils, on the other hand, are chemically engineered to provide superior performance and protection, making them ideal for modern engines that operate under more demanding conditions.

Engine oil is typically changed according to the manufacturer's recommended interval, which is usually every 5,000 to 10,000 miles or every 6 to 12 months. Regular oil changes help to maintain the engine's performance and prevent potential damage caused by excessive wear or contamination. It is important to use the correct type and grade of engine oil recommended by the vehicle manufacturer to ensure optimal performance and protection.
