- Highly stable, low volatility SAE 10W-40 allows maximum acceleration performance without sacrificing engine durability. - The HTHS of VENT VERT 10W-40 gives users ideal performance in extreme pressure conditions. The chosen viscosity guarantees engine protection thanks to its anti-wear properties (oil film thickness). The lubricant molecular structure resists extreme transmission pressure. - Specific additives create a protective layer which gives smoother gear changes, reducing mechanical and transmission noise and protects metal parts in contact. - The base oils form a homogenous oil film between the clutch disk plates to prevent clutch slippage and disk wear.
