Inquiry (采购产品): FH680V Hello, I would like to know the operating oil temp for engine model, FH680V which is attached to a Husqvarna commercial riding mower, model iz5223. I live in Florida and this summer has been extreamly hot. I install a mechanical oil temp, oil pressure gauges. After running engine for an hour the oil temp is at 250 (f) degrees with 55 psi. Is this normal? I am using GTX Casteroil 30-W and I change oil every 25 hours. I also burn Hess 89 octane fuel. The mower is only eight months old with 160 hrs on meter.
