What type of oils to use in a Roto Hoe Tiller?

If using tiller summer only, use a straight 30 weight oil from any tractor/mower dealer. If using snowblower attachment use a 10W-30 multigrade. There are two grease fittings, accessible from the top, that take normal multi-purpose grease from a grease gun. There are two more on the tine shaft, one on each side.
