Esters

Ester—these are synthetic base oils made from ester monomers, providing high heat resistance, better oxidation protection and stability at high temperatures. In XENUM technology this means the product is based on ester base oils, which enhance lubricating properties and reduce deposits. Such oils are suitable for engines that require OEM‑approval to API SN/CF, ACEA A3/B4 standards and for high viscosities (0W30‑10W60) in passenger‑car and motorcycle applications. When selecting, pay attention to the viscosity recommended by the manufacturer and operating conditions, as ester oils are especially effective under heavy loads and high temperatures.
