Most manufactures recommend SAE 10W30 or 30W. I recommend you use 10W30 Synthetic in any air cooled small engine.
Yes 10w30 is a good oil for snowblower or lawnmower.
If the wrong oil is used in a lawnmower, do not start it. Simply drain the oil as completely as possible and fill with the proper oil.
You must use the oil that the manufacturer recommends in the handbook.
NO, not in any lawnmower made in the last 40 years. Use SAE 30 or SAE 10W30 detergent oil.
