WINIRON SUPER DIESEL 15W-40 CD Motor Oil — 25 L

WINIRON SUPER DIESEL SAE 15W-40 API CD is a motor oil specifically designed for diesel engines (Diesel Engine Oil). It is formulated with Korean quality standards (Korean Quality and Technology) and Anti-Wear Technology.

According to the packaging labels, the product features an SAE 15W-40 viscosity grade and meets the API CD specification. The API CD standard (introduced in 1955) is intended for heavily loaded naturally aspirated and turbocharged diesel engines of older designs used in agricultural, construction, and commercial equipment. The 15W-40 viscosity provides a reliable oil film and stable pressure in worn engines.

The base oil type (presumably mineral), exact physicochemical properties, manufacturer details, and official OEM approvals require confirmation via the product's Technical Data Sheet (TDS).

Package volume — 25 liters (plastic canister).

Recommended for use in old diesel engines of trucks, tractors, harvesters, construction equipment, and stationary generators where the manufacturer permits the use of the obsolete API CD (or earlier) standard motor oil.

It is strictly not recommended for use in modern diesel engines equipped with Common Rail systems, Diesel Particulate Filters (DPF), or catalysts that require API CI-4, CJ-4, CK-4 standards or ACEA E-class specifications.
