4-Stroke Engine Oils

HP4S

APPLICATIONS | VIDEOS

New Pro Honda HP4S is Honda’s first fully synthetic four-stroke motorcycle oil and was quite literally years in the making. HP4S offers lower friction than conventional oils, better oxidation resistance for better high-heat performance, higher film strength and quicker flow to vital engine parts at low temperatures, especially during startup. And best of all, HP4S provides maximum power due to less frictional drag. HP4S is approved for use in all 2006 or newer motorcycles, ATVs, Scooters and PWC. It is, quite simply, our very finest four-stroke oil.HP4S is compatible with synthetic blends such as HP4, as well as regular petroleum oils like GN4. There is no need to flush the crankcases before switching to HP4S.

HP4

Thanks to the establishment of JASO standards, HP4′s extraordinary additive package offers increased antifoaming qualities, a higher viscosity index for stability over a broader range of temperatures, and even greater shear stability than most other oils. Naturally, HP4 blends the heat stability and shear resistance of synthetic oil with mineral oil’s natural lubricity, yielding premium-quality four-stroke engine oil. Best of all, HP4 is approved for use in all Honda Powersports products.

HP4M

A synthetic/ mineral-oil blend that combines the very best qualities of both types, HP4M also features a comprehensive additive package and friction-reducing molybdenum compound for maximum fuel economy and peak horsepower. HP4M – the Pro Honda oil good enough to win a multitude of AMA National championships, as well as the grueling Baja 500 and 1000.

GN4

APPLICATIONS | VIDEOS

Honda set the standard for motorcycle oil when it introduced GN4 way back in 1975. We selected the highest-quality base stocks and created an additive package specifically designed for the unique requirements of motorcycle and ATV engines. Constant testing and development give today’s GN4 even better shear resistance, viscosity stability and cleanliness to meet the requirements and stresses of a new era of engine technology.
