WINIRON PLATINUM 5W-40 SN/CF Motor Oil — 4 L

WINIRON PLATINUM SAE 5W-40 API SN/CF is a fully synthetic (Fully Synthetic) motor oil intended for gasoline engines (For Gasoline Engines). It is formulated with Korean quality standards (Korean Quality and Technology) and proprietary Anti-Wear Technology.

According to the packaging labels, the product features an all-season SAE 5W-40 viscosity grade and meets the modern API SN specification. The API SN standard provides improved protection against high-temperature deposits, reduces sludge formation, and reliably protects the engine. The 5W-40 viscosity ensures a more robust oil film at high operating temperatures, which is particularly beneficial for hot climates or higher-mileage engines. The presence of the additional CF classification indicates theoretical applicability in older generation diesel engines, but the product's primary intended use is for gasoline units.

Exact physicochemical properties, manufacturer details, and official OEM approvals require confirmation via the product's Technical Data Sheet (TDS).

Package volume — 4 liters.

Recommended for use in modern passenger car, crossover, and light commercial vehicle gasoline engines where the manufacturer permits the use of SAE 5W-40 viscosity and API SN (or earlier API SM, SL) specification motor oil.

An excellent choice for higher-mileage vehicles that require reliable wear protection and stable oil pressure maintenance. Not recommended for modern diesel engines equipped with Diesel Particulate Filters (DPF) requiring ACEA C3 class oils or similar specialized approvals.
