I too have a BG50.I also have only used trufuel,for every 2 cycle with no problems.But I may give Opti 2 a try.I’ve seen customers who have use it with no problems, but a bit expensive. I use and recommend Opti-2 in all my 2-cycle engines without any problems. Buy it only in tubes for one gallon on ethanol fuel. I don’t own any Stihl equipment now, but do have customers who follow my advice with no problems.
Stihl synthetic 2-stroke pre-mix (gray bottle) is expensive. It is also some of the best oil for the purpose on the market. As long as you use a quality oil, not some cheap Walmart crap, mix it at correct ratio (usually 50:1), and keep your gas fresh, 30-60 days, it will work fine.I'll use the gas station gas and mix myself. But after about using up a gallon of that, I'll run premix through it for at least 1 tank.
It’s pretty expensive. I’ve bought Husqvarna and Echo brand pre-mix. I usually buy TruFuel or VP. They work just as good and are cheaper.I have mixed my own or purchased the TruFuel premix from Menards to run in my older equipment for many years but recently purchased a BG 50 blower.

PT, that is the main reason I use Opti-2 in tubes. Even I can’t screw it up, 1 tube to 1 gallon of gas. Well I guess we could find some one who’s dumber than I am, but you’ll have to look for a long time, as you know I’m a retired teacher.
You could always use an empty Sta-Bil container.It's been a while, but I think I did some price shopping on those, and IIRC, it was pretty expensive. So what I do is pour the stens 2C oil into one of these. It was kind of a pita getting the oil to the bottom of this bottle. But it makes it easier to get it right.
