I decided, perhaps wrongly, to add some STP to my lawn mower's Briggs & Stratton engine. (5 HP, older Quantum)
I added about half of a standard sized bottle of STP to the half-gallon or so of gas already in the tank.
On a scale of 1 to 10, how bad of a decision was that? For reference, when I start it, it runs like a P-51 Mustang fresh off the assembly line in 1945, to the point it freaks me out and I shut it down without mowing.
