Diesel Engine Oils API CH-4 15W40

About Diesel Engine Oils API CH-4 15W40

Diesel Engine Oil API CH-4 15W40 is a premium quality heavy-duty lubricant specially formulated for high-performance diesel engines operating under severe working conditions. It is blended with high-quality base oils and advanced additive technology to provide superior engine protection, excellent thermal stability, reduced wear, and long engine life.

This multi-grade engine oil is designed for use in turbocharged, naturally aspirated, and modern diesel engines used in commercial vehicles, construction equipment, agricultural machinery, generators, and industrial applications. The API CH-4 performance level ensures excellent soot control, oxidation resistance, piston cleanliness, and protection against sludge formation.

The 15W40 viscosity grade provides outstanding lubrication across a wide temperature range, ensuring smooth engine startup in cold conditions and reliable protection at high operating temperatures.
