I have said engine in my garden tractor, which is used as a garden tractor, not mowing. It is a mostly pressure lubed engine (rear cam bearing is splash, valvetrain is splash). Manual calls for oil ranging from 5w20 for -20F to 20F to SAE30 for summer use; 30F and higher.
Engine is older, but just tore it down for valve job and new rings. All other parts within original wear specs.
Of course, this is a flathead engine, flat tappets.
There is NO OIL FILTER on this engine, oil changed every 25 hours.
In the winter I have been using synthetic 10W30. I have been using JD Torq-Guard 30wt in summer.
Should I change what I am doing, or is this a good schedule? Oh, I live in MN, so it gets COLD, and the tractor is just in a shed, no heat, but I am installing a silicon heater to the oil pan.
Thanks in advance!
