I think small engines have their oil changed frequently enough that this isn't a problem. The Burlington Northern Rail Road study in Montana was a problem as lubricating oil for railroad engines is changed infrequently, a reservoir and external filtration being employed. The Safflower oil which over time contaminated the lubricating oil was polymerized by the trace amounts of bearing metal(principally the copper if I recall correctly) found in the hot lubricating oil -- viscosity/lubrication then became a problem.

I have played with using wvo as lubricating oil in a junk engine. It's lasted longer than I thought. A block heater keeps it warm and liquid for startup, and fuel system sucks it from the oil sump, so it's always "fresh". the fuel tank feeds the oil sump. tricky part is feeding "new" oil in at rate of consumption. I'm not recommending you do this on a good engine, it's just an experiment. Steve Spence Subscribe to the Renewable Energy Newsletter & Discussion Boards.
