improve starting in cofd weather, these multi-viscosity oils
will result in increased oil consumption when used above
32°F (0°C). Check your engine oil level more frequently to
avoid possible engine damage from running low on oiL
Change the oil after the first two hours of operation and
every 25 hours thereafter or at least once a year if the tiller
