4T SAE 15W-50
DESCRIPTION
EST 4T SAE 15W-50 is a high-performance semi-synthetic four-stroke motorcycle engine oil fortified with advanced ester synthetic technology. Engineered to meet the demanding requirements of modern, high-output motorcycle engines, the incorporation of polar ester base fluids reduces internal friction losses, enhances thermal stability, and provides superior film strength under extreme operating conditions.
KEY FEATURES & BENEFITS
• Ester-Enriched Performance: Low traction coefficient synthetic ester base fluids offer superior lubricity and sharp throttle response.
• Wet Clutch Compatibility: Optimized frictional characteristics prevent clutch slippage.
• Thermal & Shear Stability: High resistance to oil thinning at elevated temperatures. .
SPECIFICATIONS
• SAE Grade: 15W-50
• API: SP
• JASO: MA2
APPLICATION & COMPATIBILITY
Recommended for high-performance air-cooled and liquid-cooled 4-stroke motorcycle engines. Suitable for modern sports bikes, cruisers, dual-sport, and commuting motorcycles with combined engine/transmission units and wet multi-disc clutches. Safe for use in engines equipped with catalytic converters.
