Product description
HD-Series products are specialized high-performance engine oils for methanol-fueled engines. Formulated through extensive engine and field testing, they effectively combat methanol-induced corrosion and rust, reduce frictional power loss, and extend key component service life.
Features and benefits
1. Superior corrosion and acidic resistance to prevent engine damage from formic acid produced during methanol combustion.
2. Low ash, high Total Base Number(TBN) and excellent TBN retention.
3. Exceptional high-temperature stability to meet demanding high-load operation conditions.
4. Superb detergency-dispersancy to minimize piston deposits, carbon buildup and varnish formation.
5. Excellent extreme pressure protection, anti-wear performance and oxidation resistance.
6. Reliable low-temperature fluidity for quick cold-start.
Applications
Recommended for
1. methanol spark ignition engines
2. methanol range extenders.
Product Recommendations:
1. H20: China VI-compliant engines*,
2. H30: China V-compliant engines
3. H40: Heavy-duty commercial engines.
*China Phase VI/V: China National Phase VI/V Vehicle Emission Standard
