    Yes but check the manufacturer specs. Sometimes they call for different oil to gas ratios.

    they’re the same type of engine and more then likely they can use the same mixed gas. BUT !!!! I would follow the manuals because different engines ask for different ratios of mix 16:1 20:1 40:1 50:1 etc…..

    a cycle or stroke of an engine is the piston traveling from the top dead center to the bottom dead center of its cylinder or from bottom to top dead center of the cylinder. the two words have the same meaning.

    yes they are the same-contrary to what the guy in the post above me said (EJ)-the amount of “cycles” or “strokes” is not just the engine moving up and down-a “2 cycle” or “2 stroke” means that there as 2 full movements that the piston makes per fire-up and down-whereas with a “4 stroke” the piston moves down (#1 intake stroke)-up (#2 compression stroke)-down (#3 power stroke)-& then up (# 4 exhaust stroke)-4 stroke.
