Briggs and Stratton are about industructable. Anything wet and slippery will suffice.
Have to agree.
Lawn mower engines are very resilient and can survive with anything resembling oil in the crank case. If two cycle engine oil can provide the necessary protection for super high revving two stroke engines, I'd be confident that it will also provide more than adequate protection for a lawnmower engine.
