CF-4 10W30 CH10W30

As a professional factory, we specialize in manufacturing high-quality diesel engine oils, with CF-4 10W-30 and CH-4 10W-30 as our core offerings, fully meeting the lubrication needs of your diesel engines.

1. API Performance Classifications

– CF-4 Grade: Complies with the API CF-4 standard, designed for four-stroke diesel engines. It delivers reliable anti-oxidation, deposit control, and anti-wear performance, ensuring stable operation under medium-duty working conditions.

– CH-4 Grade: Meets the higher API CH-4 standard, suitable for modern four-stroke diesel engines (including those with turbochargers). It offers enhanced protection against soot-induced wear, better high-temperature oxidation resistance, and superior deposit control, adapting to more severe heavy-duty operating environments.

2. 10W-30 Viscosity Grade

Both grades adopt a 10W-30 multi-viscosity formula. The “10W” enables easy cold starting and efficient lubrication in low-temperature environments, while the “30” maintains stable viscosity and sufficient oil film strength at high temperatures, providing all-round protection for engine components.
