Whats the big deal about just using what the manufacturer recommends?? I see this oil debate as silly. Anybody who has taken a Lawnboy engine apart can see there is no "excessive" oil remaining in a Lawnboy engine, the bearings have just a little oil coating them. The only Lawnboy engines I have ever had that visibly smoked at any point when tuned up correctly are the Duraforce models with the above-deck muffler. I say just use the 1:32 ratio Lawnboy recommends regardless of the 2-cycle oil brand used.
