Belray H1R
I've used belay since the 90s after busting a pistion on a sweet smelling oil I won't mention. It has never let me down even when I've went a little long on top end rebuild. Everything always looks good and clean. Powervalves and all. It's expensive but worth the extra money for peace of mind for me.

Great premix oil
Made my 4-mix backpack blower run much better. Pulls to a higher rpm and gets there quicker. I am running 40 to 1 and using avgas. No smoke or deposits on muffler outlet so far. Two tankfuls ran so far.
