Low viscosity synthetic engine oil flows through the engine faster to get to where it’s needed more quickly, generating less friction than conventional mineral oil so the engine operates more efficiently.
Modern car engines are between 15 and 20% efficient, losing up to 85% of the fuel’s energy to friction within the engine, rolling resistance from the wheels, braking and the gearbox. Friction losses inside the engine are one of the largest consumers of energy and synthetic oil reduces these losses. The less energy consumed by friction and dissipated as heat, the more can be used to drive the wheels. Fully synthetic oil, such as Mobil 1, makes each litre of fuel last longer, cutting your costs.
