Semi Syn 10W/40 SN/CF stands as a top-tier API SN/CF engine oil, renowned for its premium quality. It proves itself compatible with a wide range of four-stroke engines, including petrol, diesel, and LPG variants, even when subjected to challenging and diverse operational conditions. This oil finds its true calling in professional workshops.

Crafted from superior base oils, Semi Syn 10W/40 SN/CF excels in preventing engine oil oxidation, delivering heightened protection against piston deposits compared to standard SN engine oils. Additionally, it champions engine cleanliness through an elevated level of dispersants, effectively curbing sludge formation, especially during the constant cold-temperature demands of urban driving.

Notably, Semi Syn 10W/40 SN/CF earns accolades for its exceptional cold-starting capabilities, thanks to its excellent fluidity characteristics. It further extends engine longevity by reducing wear rates for vital components like cams and bearings when contrasted with less advanced oils.

For those demanding high-temperature performance, Semi Syn 10W/40 SN/CF stands out. Its selection of thermally stable base oils, oxidation inhibitors, viscosity improvers, and detergents enhances its resilience under elevated temperatures.

In essence, Semi Syn 10W/40 SN/CF proves itself versatile, suited for low-temperature stop-and-go driving, high-speed motorway cruising under scorching conditions, and engines with tight tolerances.
