10W40 - Synthesis
A high-performance semi-synthetic lubricant, R4000 RS is recommended for modern high performance machines.
- Formula contains added extreme pressure modifiers for excellent lubrication of integrated gearboxes.
- Compatible with catalytic converters.
- Viscosity is suitable for a very wide range of temperatures: SAE 10W for starts in very cold weather (recommended for hydraulic tappets), and SAE 40 for high engine temperatures.
R4000RS has excellent shear stability. Its low volatility reduces oil consumption and its high lubricating power reduces friction.
