The subject of the article is a synthetic lubricant for the latest generation internal combustion engines, used especially in passenger cars, equipped with both spark ignition engines and compression ignition engines, which is used in particular in passenger cars operating in urban conditions, overcoming relatively short distances, and therefore working usually below the recommended operating temperature of the engine. The developed 5W30 oil maintains excellent rheological properties (fluidity) also before reaching the correct operating temperature of the engine, especially at negative temperatures, which results in lower oil pump resistance and reduced friction of key engine components, which ensures better engine working conditions and affects its service life.
