Abstract: The invention provides a method for lubricating a two stroke cycle fuel injected internal combustion engine of petroil type. A port or manifold injection system and a direct injection system form part of the engine. Fuel and oil are pre-mixed and supplied to the port or manifold injection system for a port or manifold injector to deliver lubricant to the crankcase of the engine. The method allows lubrication of engine components in accordance with engine operating conditions.
