Additive for large tank of boat gas?

I have been using starbrite ring free with non ethenol gas so far no problems with fuel .
Yea there's just no non-ethenol gas where I'm at. I put Lucas Oil gas treatment in it, measured for 150 gal. Then I had some spare room, I thought it was full, but put another 40 gal in at the pump so hopefully the fresh fuel and the lucas oil help.
