Its formulation balances extreme-pressure additives with friction modifiers so gears and clutch packs operate reliably while resisting wear, foaming and corrosion. Motul 90 PA meets API GL-4\/GL-5 and MIL-L 2105 D specifications and is compatible with typical seals found in drivetrain assemblies.\u003c\/p\u003e\n\n\u003ch3\u003eHow will Motul 90 PA improve gearbox and differential longevity?\u003c\/h3\u003e\n\u003cp\u003eMotul 90 PA reduces metal-to-metal contact under heavy loads by providing a durable lubricating film and extreme-pressure protection.
