I have John Deere mower with B&S engine. I just replace oil once a
year,when winter comes store it away. Been 10 years doing this. it starts
OK in the spring with couple pulls, still runs like new.
Same with my Toro 2 cycle snow blower, chain saw, weed eater too. never
had serious problem or damage.

You replace the oil on your 2 cycle snow blower, chain saw, and weed eater!
I have never been able to find the oil on mine.
