Product Introduction
Loader Special Engine Oil is a heavy-duty high-performance lubricant designed exclusively for loader diesel engines, meeting API CH-4, CI-4, and construction machinery specifications (e.g., Caterpillar ECF-3, Komatsu DT-4).
Formulated with synthetic blend base oils and advanced additive technology, it delivers exceptional wear protection, soot control, and thermal stability for loader engines operating under heavy loads, high temperatures, and harsh working conditions.
This engine oil ensures reliable lubrication for turbocharged diesel engines, reduces piston ring and bearing wear, and protects against oxidation and corrosion, extending the service life of loader engines.
It is widely used in loaders from global manufacturers (Caterpillar, Komatsu, Sany, XCMG), adapting to construction sites, ports, and material handling operations.

Production Process
The production of Loader Special Engine Oil involves state-of-the-art manufacturing techniques: high-quality synthetic blend base oils are selected for their viscosity index and soot dispersancy. The base oils are then mixed with a proprietary additive package in a closed blending system, with strict control of temperature and mixing speed. The mixture undergoes vacuum dehydration and multi-stage filtration (3μm precision) to remove impurities and moisture. Each batch is tested for wear protection, soot control, and manufacturer compliance to meet API CH-4/CI-4 and construction machinery standards.
Packaging & Shipping
