Turbo Diesel Synt 10W-40 is a premium fully synthetic engine oil belonging to the UHPD (Ultra High Performance Diesel) class, formulated for the latest generation of heavy-duty diesel engines. With its carefully calibrated low-SAPS chemistry, this oil delivers top-tier protection while maintaining full compatibility with modern exhaust aftertreatment systems.

This engine oil is specifically engineered for commercial vehicles equipped with exhaust gas recirculation (EGR), selective catalytic reduction (SCR), and diesel particulate filter (DPF) systems. Its reduced sulfated ash, phosphorus, and sulfur content prevents premature clogging of particulate filters and protects catalytic converters from poisoning, ensuring compliance with Euro V and Euro VI emission standards throughout extended service intervals.

The fully synthetic base oils provide excellent performance across a wide temperature range. At cold temperatures, the oil flows quickly to deliver immediate engine protection during startup, minimizing the critical wear period before full oil pressure is established. Under high-temperature, heavy-load conditions typical of long-haul trucking and vocational service, the oil maintains outstanding thermal stability and film strength, preventing deposit formation and oil breakdown.

Key benefits include exceptional wear protection for all engine components, superior soot handling that prevents oil thickening and abrasive wear, effective oxidation resistance for extended drain capability, and reliable corrosion protection. Turbo Diesel Synt 10W-40 is recommended for trucks, buses, construction equipment, and other commercial vehicles with modern diesel engines. Fleet operators benefit from reduced maintenance costs through extended drain intervals, lower DPF-related downtime, and improved fuel efficiency compared to conventional mineral oils.
