improve starting in cold weather, these multi-viscosity oils
will result in increased oil consumption when used above

avoid'possible engine damage from running low on oil
Change the oil after every 25 hours of operation or at least
once a year if the tractor is not used for 25 hours in one year.

and after each five (5) hours of continuous use° Add SAE
30 motor oil or equivalent. Tighten oil filler plug securely
