Is it ok to use 20-50w engine oil in a lawn mower?

No, it is not okay to use 20-50w engine oil in a lawn mower. Lawn mowers typically require SAE 30 or 10W-30 oil as this will keep an operating engine from stalling in the heat in which lawn mower typically run while providing more sufficient lubrication compared to thicker options like the suggested one: 20-50w engine oil.
