Agreed
I'm not totally convinced on the synthetic at 100-1 VS petroleum at 32-1 thing...I kept adding oil to some fuel last week...It ran the same until too much oil caused it to quit..I picked up 200 rpm once years ago on a Zenoah 445 twin by running 20-1......
I have some Amsoil 100-1 here, will try it VS Pennzoil 2 stroke at 32-1 in the same engine, same prop, same everything...
