Fenix Univerzal SAE 10W is a single-grade mineral engine oil formulated for high-efficiency lubrication of diesel engines in transport vehicles, trucks, agricultural machinery, and construction equipment of older generations. This monograde oil is designed for engines that specifically require this quality level and SAE viscosity grade, providing proven, reliable protection throughout the year.

Single-grade SAE 10W oil is characterized by its lighter viscosity, which provides excellent cold-weather flow properties and quick oil circulation at startup. This ensures rapid lubrication of all engine components during cold starts, reducing the critical wear that occurs before full oil pressure is established. The lighter viscosity also contributes to easier cranking in cold conditions and reduced parasitic drag on the engine.

Fenix Univerzal SAE 10W is formulated for all types of high-speed diesel engines found in the commercial and agricultural sectors. Its mineral base oil formulation enhanced with quality additives delivers effective wear protection for bearings, pistons, cylinder walls, and valve train components, while detergent and dispersant chemistry keeps engine internals clean and prevents harmful deposit accumulation.

Additional benefits include good oxidation resistance that preserves oil quality during service, reliable corrosion protection for internal metal surfaces, and effective soot handling in diesel applications. This oil is recommended for older-generation engines where the manufacturer specifies single-grade oil — modern engines typically require multigrade lubricants and should use the appropriate product. Fenix Univerzal SAE 10W is a straightforward, economical lubrication solution for maintaining legacy diesel equipment that was designed to operate with monograde engine oils.
