Synthetic oils provide motorcycle engines an improved cold start due to the lack of wax found in conventional oils but not in manufactured ones, which thicken the oil when it is cold or overnight while the bike is not in use. By smoothing the start, synthetic oils decrease engine wear and improve fuel efficiency.
