Honda Pro HP4 10W-40 Motorcycle Oil, Case of 4 (4×32 oz) — Synthetic-Blend, Racing-Proven Protection

Pro Honda HP4 10W-40 is a premium synthetic-blend 4-stroke motorcycle oil supplied in a case of four 32 oz bottles, formulated for Honda Powersports engines and racing-proven performance.

Designed and tested with input from Honda’s motorsport teams, Pro Honda HP4 blends synthetic and mineral base stocks to deliver stable viscosity, improved shear resistance, and enhanced anti-foaming properties across a wide temperature range. This oil meets the specific demands of air- and liquid-cooled four-stroke motorcycle engines and is approved for use in Honda Powersports products, making it an ideal service choice for maintenance, tune-ups, and performance-oriented riders.

How does Pro Honda HP4 protect my motorcycle under varying temperatures?

HP4’s 10W-40 viscosity rating and elevated viscosity index keep the film strength consistent from cold starts through high operating temperatures. The synthetic components improve high-temperature stability while the mineral fraction contributes natural lubricity for smooth running.

• Viscosity grade 10W-40 for reliable cold start flow and hot protection
• Higher viscosity index reduces thickness change with temperature
• Synthetic blend resists thermal breakdown during long rides
• Anti-foaming additives maintain film integrity under stress

Will this oil hold up during aggressive riding or track days?

Pro Honda HP4 is engineered with shear-stable additives to resist breakdown under high loads and rpm, traits honed through racing development. It helps maintain consistent lubrication and reduces the risk of viscosity loss during repeated high-stress use.

• Enhanced shear stability for extended high-load protection
• Reduced viscosity loss after sustained high-rpm operation
• Formulation informed by professional motorsport testing
• Suitable for both spirited road riding and track conditions

Is Pro Honda HP4 compatible with my Honda Powersports model?

HP4 is approved for use in all Honda Powersports products and is formulated to meet the lubrication needs of modern four-stroke motorcycle engines. Always consult your owner’s manual for recommended oil viscosity and service intervals before changing products.

• Approved for Honda Powersports motorcycles and ATVs
• Works with wet-clutch systems where 10W-40 is specified
• Ideal for both air-cooled and liquid-cooled four-stroke engines
• Follow manufacturer guidelines for oil-change frequency

What are the packaging and value benefits of the case option?

Buying the case of four 32 oz bottles gives you enough oil for multiple changes or for servicing several machines, and reduces per-bottle cost compared with single purchases. The case format is practical for garages, small shops, and riders who prefer to keep a ready supply on hand.

• Case includes four 32 oz (quart) bottles — ready for multiple services
• Convenient storage and bulk value for frequent maintenance
• Individual bottles have pour-friendly necks for easy draining
• Same Pro Honda formulation used in racing and OEM service
