Will a four-stroke lawn mower with no oil in it hold up long enough to mow my lawn once before I throw it out?

This mower burns oil, and I think the rings are shot. I'm going to get around to getting another junk mower, but for the time being, do you think I can get by with mowing just once with no oil in the crankcase? It's a pain right now because I have to constantly clean the plug... perhaps 15 times in a single session of mowing the lawn. Do you have any ideas for a flammable lubricant I can put in there that will burn cleanly enough to not foul the plug? (I considered using 2-stroke oil or even gasoline in the crankcase.) Keep in mind that I'm not interested in any spectacular longevity... just to get me through until I can replace it.
