I use 50:1 with Sthil 2-stroke oil in ALL my 2-stroke equipment. This ratio does not smoke at all, and does not foul plugs.
Never had a problem yet. At this mix ratio, you can also use it in 4-stroke engines, which means you only need 1 fuel can on site. Also eliminates the possibility of using the wrong can to fill the trimmer.
