Bel-Ray V-Twin Full Synthetic 10W-50 Engine Oil 1 Liter

Bel-Ray V-Twin Full Synthetic 10W-50 Engine Oil 1 Liter

When cold starts matter as much as sustained high-output protection, 10W-50 gives your V-Twin an edge that 20W-50 cannot. The lower cold-weather viscosity flows to critical engine components faster at startup, while the same SAE 50 high-temperature protection ensures no compromise when the engine is fully up to temperature. All the extended-interval, full-synthetic coverage of Bel-Ray’s V-Twin line — with faster oil delivery on every cold start.

Key Features

• 100% Synthetic Ester and PAO base fluid — full-synthetic formulation for large-displacement V-Twin engines
• 10W cold-weather viscosity flows faster at startup than 20W-50 alternatives, delivering quicker oil pressure build at cold start
• Superior film strength provides increased protection for critical engine components
• Exclusive Bel-Ray anti-wear chemistry reduces bearing and valve train wear and prevents piston and ring scuffing
• Highest Viscosity Index for stable viscosity protection across a wide temperature range
• Exceptional shear stability and low-volatility base oils resist viscosity breakdown for longer drain intervals
• Reduced friction decreases engine operating temperature for sustained high-output riding
