The bike is more responsive, smoother/quieter, and the oil flows very well. Paired with a k&n oil filter this oil really puts in the work. I just made the swap from conventional to full synthetic, and I will not be going back. Review: Best formula for proper component lubrication and longevity. - Best oil for Harley M8 motor.

Ester molecules form a persistent bond with metal surfaces, maintaining a stable protective layer under the thermal stress of air-cooled, high-displacement V-twin engines. API SP certified additive package delivers advanced wear protection, oxidation resistance, and deposit control throughout the full drain interval - JASO MA2 Certified — Precise Wet Clutch Engagement and Gear Response: JASO MA2 (T903:2023) certified for optimized wet clutch performance, delivering sharp and consistent gear engagement across the entire operating temperature range. The ester-based formulation enhances friction-surface adhesion for responsive throttle feedback and reduced drivetrain vibration in motorcycles with integrated engine-gearbox-clutch systems. Formulated to maintain stable friction coefficients that ensure predictable clutch feel whether cold-starting or at sustained operating temperature - Engineered for Air-Cooled, High-Temperature V-Twin Operation: Specifically formulated to maintain viscosity stability and film integrity under the extreme thermal demands of air-cooled, high-displacement engines operating at sustained highway speeds and elevated ambient temperatures. The synthetic ester base resists thermal breakdown and viscosity loss at operating temperatures where standard formulations degrade, ensuring consistent lubrication across all riding conditions. Recommended for Harley-Davidson Milwaukee-Eight, Twin Cam 88/96/103/110, Evolution 1340, and Sportster 883/1200 powerplants - Extended Drain Interval Performance — Advanced Oxidation Stability: API SP additive package provides measurable oxidation stability, sludge resistance, and internal engine cleanliness over the full OEM-recommended drain interval. The 100% synthetic ester base maintains protective and detergent properties at the elevated operating temperatures typical of air-cooled motorcycle architectures, reducing deposit formation on critical engine components. Compatible with motorcycles equipped with catalytic converters and exhaust after-treatment systems for emissions-compliant operation - Application Compatibility — Harley-Davidson, URAL, and SAE 20W-50 V-Twins: Recommended for Harley-Davidson and URAL motorcycles requiring SAE 20W-50 viscosity grade in the engine. The reinforced anti-wear additive package, inspired by 300V motorsport technology, provides the film strength and thermal resilience demanded by high-displacement, air-cooled V-twin powerplants. Available in 1-liter and 4-liter sizes with packaging manufactured from 50% recycled plastic that is 100% recyclable.

Might want to double check your owner's manual. **Q: can this be used for all 3 holes? Engine, Transmission and Gear box?** A: Just two - Main and primary. Not the gear box. For that use Motul Gear 300, 75-90. **Q: Can this be used in all three holes on a 2020 Milwaukee 8?** A: I've been using the Motul 20-50W in the main and primary of my 07 Fatboy for 14yrs. It's fabulous! -- But not in the gearbox. For gear box I recommend using the Motul Gear 300 75-90W. **Q: Is it full synthetic?** A: Yes indeed, 62,000 mi on Ducati Multistrada. Never tasted any other oil...... ## Customer Reviews ### ⭐⭐⭐⭐⭐ Best oil I could have chosen *by A***O on February 25, 2026* Motul is already a renowned brand, so I knew I was getting quality, but I didn’t imagine the actual change I would see.
