10-40 SAE
A 40cc engine wont even touch 40mph. It stresses a 175cc engine to go 40mph. A 40cc engine will go roughly 10 miles an hour based on how much the engine weighs and how much weight you put on top of it.

Newer engines are machined to tighter specifications than older motors. Newer motors require a lighter grade oil for lubrication like a 5 or 10 weight. The 5 or 10 weight can move through the engine and get to the places that need lubrication better than a heavier grade of oil. A 10-40 grade moves through the engine like a 10 weight oil with the ptotection of a 40 weight oil. If you put a 30 weight oil in your engine, it will not move through your engine as easily and when it does get to the parts that need lubrication, it does not do as good of a job.
yes most people in the Texas area run 15w-40 it will depend on your weather.
A 1995 Escort wagon takes either 10-30 or 10-40 weight oil. The lower weight oil should be used in the winter to prevent the oil from gumming up the engine.
