Tis the season to get all our junk out and get it ready for planting.  I've got a Honda GX160 on a fertilizer trailer that seems to leak most of its oil out each year to the point it won't fire because of the low oil shutdown safety.  The engine is dirty and wet but I don't recall having to add oil to it during the planting or side dressing seasons.  Its 20+ years old and still runs fine but I'm curious where the oil leaks out on these things.
