An inappropriate choice of lubricant

I put two-stroke oil into my four-stroke lawn mower engine. How bad is that?

I mistakenly used two-stroke (2T) oil (unmixed with gas) to fill the oil reservoir on the lawn mower. It ran fine, and started easier than usual, I'd say. How immediately should I replace the oil with the conventional 30-wt oil actually specified by the engine? Is there a big viscosity difference that will damage the engine if I leave the two-stroke oil in it?
