Oil Man is one of the six Robot Masters from the Mega Man 3 (PC) computer game for DOS. This version of Oil Man is not the same as the Oil Man designed by Dr. Light and reprogrammed by Dr. Wily in Mega Man: Powered Up.
Oil Man resides on an oil refining plant and is equipped with an oil-shooting arm cannon (it shoots high-pressured oil in an attack called the Oil Stream). He is very fast and mobile, but he is weak against the sharp blade projectiles of the Blade Launcher used by Blade Man.
- Oil Man's mugshot is an edit of Flash Man's mugshot from Mega Man 2, and his design closely resembles Flash Man as well.
- Oil Man's weakness against Blade Man is probably because blades could, if they are sharp enough, cut into an oil pipe and the oil would leak from of the pipe.
- Oil Man's primary weakness is Blade Launcher, but Water Shooter and Shark Boomerang are also effective.
