Z725 Oil

[Brazos]

I have a Z725 with the Koehler motor in it. The manual says 10W30 with an AP rating of SG, SH, or SJ. I went to Wal-Mart and could not find oil with those AP ratings. I noticed my 4-wheeler manual recommended the same AP ratings so I went to a motorcycle shop and no luck. When I change the oil in the Z725 am I just changing the engine oil or am I also changing gear oil at the same time like I do when I change the oil in my 4-Wheeler? If I am just changing the engine oil then any quality 10W-30 would do. If when I change the engine oil but also a gear box oil with clutches, etc. then I need to keep looking I guess.

Those service categories are long obsolete. Current specification is SN or SP.
