Cool lawnmower UOA! Always enjoy these. I need to do one of my FIL's. Its like 7 years old and had only three oil changes albeit with high quality oil. I'd better change the oil in it soon I guess.

Looks like a good oil for an older engine. Good add pack with a high TBN. May try it out in my sbc powered farm truck.
