Viscosity controlled according to temperature: the additives in ELF MOTO4 ROAD 10W-40 thicken the oil at high temperature and make it more fluid at low temperature. The optimal oil film is achieved by controlling viscosity according to temperature using viscosity index improvers. Its viscosity provides superior lubrication, ensuring easy cold starts, rapid oil pressure rise, and low friction between moving engine components. Piston ring seal, power gain: reduces groove fouling for optimal seal during combustion. This ensures the engine retains all its power. Oxidation resistance: antioxidant additives that neutralize and slow down the oxidation process. Clutch anti-slip, disc protection: the base oils form a homogeneous film between the discs thanks to their molecular structure.
