Honda GN4 10W-40 4-Stroke Engine Oil Case (12 Quarts) — OEM motorcycle, ATV & UTV formula for high-RPM protection

Honda GN4 10W40 is a genuine OEM 4-stroke engine oil sold as a full case (12 quarts) engineered for motorcycles, ATVs and UTVs to provide stable viscosity and internal cleanliness under real-world riding conditions.

Honda GN4 10W40 (part number 08C35-A141M01) is a factory-formulated engine lubricant developed specifically for modern air- and liquid-cooled four-stroke motorcycle and powersports engines. The GN4 line combines high-quality base stocks with advanced shear-resistant polymer additives to resist viscosity breakdown, control wear and help keep internal components clean. This case delivers a ready supply of genuine Honda oil for maintenance schedules or fleet servicing.

How does GN4 10W40 protect my engine during high-rev riding?

GN4’s formulation emphasizes shear stability and thermal resistance so the oil maintains protective film strength at elevated temperatures and sustained RPM. That keeps clearances lubricated and reduces metal-to-metal contact when engines are pushed hard.

• Shear-resistant polymers reduce viscosity loss under stress
• Premium base stocks provide stable film strength at high temperatures
• Designed for continuous high-RPM motorcycle and ATV operation

Will this oil work across different types of Honda powersports machines?

Yes — GN4 10W40 was created to meet the demands of a broad range of four-stroke Honda motorcycles, ATVs and UTVs. It supports clutch compatibility and transmission demands common in combined engine/gearbox designs, while still protecting the engine's internal components.

• Formulated for four-stroke motorcycle, ATV and UTV engines
• Compatible with wet clutches and integrated transmissions in many models
• Genuine OEM specification ensures fit for Honda service recommendations

What maintenance advantages come from buying a full case of 12 quarts?

Purchasing a case of 12 quarts reduces frequent reordering and guarantees you have the right OEM oil on hand for scheduled changes or multiple vehicles. It’s convenient for workshops, riding groups or owners who prefer stocking genuine parts for consistent maintenance.

• Enough oil for multiple oil changes or several vehicles
• Simplifies preventive maintenance for fleets or frequent riders
• OEM part number 08C35-A141M01 ensures authenticity and warranty alignment

How does GN4 help keep my engine clean and prolong component life?

GN4 includes detergent and dispersant chemistry tuned for motorcycle engines to minimize deposit formation and keep oil passages clear. Cleaner oil circulation supports consistent lubrication and helps extend the life of bearings, cams and piston rings.

• Detergent additives reduce sludge and varnish buildup
• Dispersants suspend contaminants until drained at service intervals
• Improved cleanliness contributes to longer component life and consistent performance

Who is this for: this case of Honda GN4 10W40 is aimed at owners and shops that service Honda motorcycles, ATVs or UTVs and prefer OEM-specified lubricants. It’s also a practical choice for riders who perform regular maintenance, fleet operators who need consistent supplies, and anyone who wants a genuine Honda part number (08C35-A141M01) to match factory service recommendations.
