Depends on the engine, and how it's cooled. Air-cooled engines typically run quite hot, and a heavy oil is necessary (20W to 30W oil). Liquid cooled engines typically run a bit cooler and can run a lighter oil (15W to 20W). For example, I have a 5.5 HP Honda air-cooled engine on my push mower and it requires 30W oil.
Best answer I can give you is check with your owner's manual or call/contact the engine manufacturer and they can give you a definite answer. Opt for synthetic oils with the manufacturer's recommended weight. Just like your car, lawnmower engines benefit from high grade synthetics, and the added cost for the oil is quite minimal.
