Try the HP Ultra, or Amsoil. With the Stihl HP, I never see any
smoke unless one of my machines are started cold, and at lower temps. The smell is also much, much less than with std Stihl orange bottle oil or other brands of oil including some semi synthetics that I've tried.
With Amsoil mixed at 80:1, or 100:1 there's so little oil in the fuel mix as to be almost undetectable in smoke or smell, yet it is guaranteed to work at that ratio.
