I need to replace the transmission oil in my Gravely garden tractor.
Over the years spec changed from straight 30 to 10W40 and now 10W30 motor oil.
am wondering if better to use a semi synthetic which might be less likely to leak at old seals.
Rotella 5 or 6?
old straight cut gears, don't get hot, probably some slop in them.
