Thought I might anger the gods and try something new. I took my weed whacker and instead of using regular 2 stroke oil with the gas I'm using a 40-1 ratio of gas to biotech. Makes a pretty purple fuel and purrs like a kitty.
Why not shoot the company an email and fill them in on your experiment? They can tell you the factual pros and cons if any, and what the long term outcome would have been had you continued.
Considering that in years gone by, 2T oil wasn't anything other than non detergent 30 weight, I'd say while LubeGard Biotech isn't optimal, there are many other poorer choices. I'd expect deposits from the Moly and Boron.
Heh heh and I thought I was living on the edge using Valvoline Universal TCW3 rated oil mixed 32:1 in my weed wackers and chain saw. I never understood how an ashless oil could be bad for a air cooled 2 stroke
