just picked up a used lawnboy push mower with a 6.5 tecumseh. gonna do a basic tune up, new oil, plug, etc. it calls for SAE 30, but i was thinking of going with a 10W30 synthetic or some old CI-4 Rotella 5W40 i have left over. would either of these oils hurt it? and would the 40 wt cause more strain on the engine?
tecumseh 6.5

Q.
The Briggs or Snow King single grade 30 usually have the high zddp required for non-pressure lubed engines. Most spark plugs should easily last the life of the engine if they dont get too zinc fouled. BTW, Dont use easy start extended tip plugs or gimmick plugs, just your basic champions.

I have a 4 HP Tecumseh on a 1990 Craftsman mower, used mostly 10W-30 dino. Still going strong (but the mower deck is falling apart).
yeah i know what a real lawn boy is, i have a 2 stroke one. i also got some 10W40 honda motorcycle oil, would that also do good in this engine? SJ label
Rotella 10w30 or 5w40 will work great in that engine.
