2003 Toro Z-Master 74179 , Z149 hydraulic pump

[melsauto]

Filter part number is 1-633752 it takes 15w50 synthetic oil .my mowers say Mobil 1 oil only on cap but toro site say nothing about using only Mobil 1

What would be the filter part numbers for Engine oil, fuel, and part number for spark plugs(after market) can i get these in Napa parts .
