I understand that, but 10w30 is what’s the manufacturer recommends.Pressure washer and riding mowers run hot. Probably want at least a 40 weight.
Being a pressure washer the winter rating is probably irrelevant as you're not using it much at or below freezing.
My pressure washer oil hits 280f so it gets a 50 weight oil. Specially 20w-50 since I don't plan on starting it anywhere near freezing.
Me personally I don't think I've ever started my riding mower below about 40f. Even then all I did was move it to the back yard.
