ULTRA 1PLUS 4T 10W-40 Synthetic Blend Motorcycle Oil 1 Gallon — JASO MA2, API SL for Wet Clutches and Year-Round Protection

ULTRA 1PLUS 4T 10W-40 Synthetic Blend Motorcycle Oil is a JASO MA2 and API SL-rated engine oil formulated to protect four-stroke motorcycle engines and wet clutches while improving fuel economy and reducing wear.

This 1-gallon synthetic blend 10W-40 from ULTRA 1PLUS is designed for riders who need reliable, year-round lubrication in a wide range of motorcycles and ATVs. It balances high- and low-temperature performance to ensure smooth startups, consistent oil pressure, and clean engine internals across varied riding conditions. With JASO MA2 certification, it supports wet clutch compatibility and predictable shifting under load.

How does this oil protect my engine during long rides?

The ULTRA 1PLUS 10W-40 blend reduces internal friction and helps prevent metal-to-metal contact by maintaining a durable lubricating film under heat and stress. Its formulation minimizes deposit formation and sludge, which keeps oil passages clear and extends component life.

• High-viscosity base for consistent film strength at operating temperature
• Detergent and dispersant additives to limit sludge and deposits
• Wear inhibitors to protect bearings, cams, and pistons
• Stable shear resistance to preserve viscosity over time

Will this oil work with my motorcycle’s wet clutch?

Yes — ULTRA 1PLUS 4T 10W-40 meets JASO MA2 standards, which ensures friction characteristics suitable for wet-clutch systems. That means predictable engagement, reduced chance of slippage, and smooth shifting under varied loads.

• JASO MA2-certified for wet clutch compatibility
• Engineered friction profile for positive clutch feel
• Reduces clutch chatter and slippage risk
• Appropriate for shared engine/transmission oil systems

Can I use this oil in different climates and engine types?

The 10W-40 viscosity rating provides dependable cold-start protection and robust high-temperature performance, making it suitable for many climates year-round. It’s formulated to protect both air-cooled and liquid-cooled four-stroke motorcycle and ATV engines.

• 10W cold-start flow for easier ignition in cooler weather
• 40-weight protection at operating temperature for hot conditions
• Compatible with air- and liquid-cooled engines
• Works across a wide range of street, touring, and off-road machines

How does this oil impact fuel economy and throttle response?

By minimizing friction and reducing deposits, the ULTRA 1PLUS synthetic blend helps the engine run more efficiently, which can improve fuel usage and throttle feel. Cleaner internals also preserve power delivery and keep the throttle response sharp over longer intervals between services.

• Low-friction formulation to reduce parasitic losses
• Detergents that limit power-robbing deposits
• Improved throttle response through reduced drag
• Helps maintain fuel efficiency across service intervals

Who is this for? Riders and mechanics looking for a versatile, dependable motorcycle oil: ULTRA 1PLUS 4T 10W-40 is ideal for owners of four-stroke motorcycles and ATVs that use shared-sump oil systems and require JASO MA2 compatibility. It suits commuters, weekend tourers, and off-road enthusiasts who need a single oil that delivers wear protection, clutch-friendly friction, and reliable all-season performance.
