Think OP wrote wish there was a 15w40 Synthetic? guess Royal Purple has their version and others have 5w40 …
If it was mine I would use 10W30 white bottle Red Line. Probably over kill but I like the polarity aspects of the high ester content for a splash lubed motor.
kolher engines need extra zinc and 10w-30 only! I only use kolher brand oil in mine. learned this the hard way. dealers or small engine shops and tractor supply have it
