Honda Pro GN4 10W-30 Motor Oil — 1 Gallon OEM Formula for Motorcycle Wet-Clutch Engines

Honda Pro GN4 10W-30 motor oil is a factory-formulated 4-stroke lubricant in a 1-gallon size designed to protect modern Honda engines and maintain stable viscosity under riding conditions.

Developed by Honda engineers, Pro GN4 blends high-quality base stocks with additive chemistry tailored for the lubrication, shear resistance, and cleanliness demands of contemporary motorcycle and powersports engines. This 08C35-A131L02 formulation meets the unique mechanical and thermal stresses found in compact, high-revving powerplants, offering consistent performance that aligns with Honda service recommendations.

How does this oil help everyday riding and engine longevity?

Pro GN4 reduces wear by maintaining a protective film across critical components during startup, cruising, and high-load situations. It resists viscosity breakdown so clearances remain stable and parts retain engineered tolerances longer.

• Shear-resistant additives preserve viscosity under mechanical stress.
• High-quality base oils minimize friction and surface wear.
• Detergent and dispersant agents keep combustion byproducts and sludge suspended.
• Formulated specifically for motorcycle wet-clutch and gearbox compatibility.

What makes Honda Pro GN4 different from generic 10W-30 oils?

Unlike universal formulations, Pro GN4 is engineered to Honda's specifications with additive blends tuned to their engines' tolerances and operating profiles. That alignment reduces risk of unwanted clutch slippage, corrosive wear, or accelerated viscosity loss that can occur with non-matching oils.

• Factory-specified additive package for Honda powertrains.
• Viscosity stability tailored to high-revving motorcycle operation.
• Designed to meet wet-clutch performance requirements.
• Produced to the same quality control standards used by Honda service parts.

How should I use and store this 1-gallon container?

The 1-gallon size is ideal for routine maintenance or multiple oil changes. Store in a cool, dry place away from direct sunlight and clear labeling before pouring ensures the correct oil type is installed according to service intervals.

• Follow Honda owner's manual for oil-change intervals and capacity.
• Use a clean funnel to avoid contamination when filling.
• Store upright at moderate temperature, tightly sealed to prevent moisture ingress.
• Dispose of used oil responsibly at an approved recycling facility.

Who is this for? Riders and DIY technicians who own Honda motorcycles or compatible small engines and want an OEM-recommended lubricant benefit most from Honda Pro GN4 10W-30. It's especially suited to owners who prioritize factory-matched chemistry, consistent viscosity under load, and wet-clutch compatibility for everyday commuting, spirited weekend rides, or regular maintenance schedules.
