When comparing to a two-stroke engine, the four-stroke engine has the following advantages.
Fewer emissions. Since the crankshaft has its own oil reservoir there is no need to add oil to the fuel, meaning there is no oil burned in the fuel.
Better fuel consumption. The four-stroke engine complete a full cycle in four-stroke. This gives it greater control over which ports open at which times. On a two stroke engine, fuel and air is being forced into the cylinder while exhaust is being forced out, this causes some fuel and air to flow directly through the cylinder and out the exhaust. Four-stroke engines are also directly fuel injected which allows greater control over fuel delivery.
Longevity. The four-stroke engine has a lower power to weight ratio than the four-stroke engine. In this respect, the engine components aren't pushed as hard as a two-stroke. This allows them to last longer.
