Put some 4 cycle Tru Fuel in my BR 800 blower

Hi folks...first time homeowner and small engine noob here. Well...I finally did it! Put the wrong fuel in one of my machines. Didn't fill the tank (half full at most). Probably ran it for 10-20 min total. It's Tru Fuel if that makes a difference. Quick google suggests it's worse to gas/oil mix in a 4 cycle than other way around. 
 
Would you a) dump it out, or b) fill rest of the way with 50:1. Suppose I could also add the ratio of oil to what's left.  
 
Curious to hear more from those who know more than me. Obviously safest is to remove it. 
 
Anything you'd add to the first tank with the right fuel? 
 
Thanks!

    Dump the fuel and put the proper two stroke oil / and proper mix in it.  
     
    Just an FYI, that engine does run on two stroke oil but, in fact, DOES have intake & exhaust valves (4 MIX). 
    It is a 4 stroke engine (with no oil sump), the pre-mix fuel goes down a separate orifice to lube the valves, crank, etc, (see below pic.)
     
    It's not a cheap machine so I'd either run Red Max or Stihl oil in it.
     
    Below is a BR 600 I repaired after a valve retainer broke at WOT and dropped a valve
    bending it. 
    A commercially used machine

    Thanks! That's just the feedback I was looking for. Just learned about TruFuel last year, and didn't realize RedMax and Stihl had their own versions of it. I'll look into those. 
     
    Pics didn't come through but thanks for sharing. And thanks for 2 v. 4 stroke explanation. My friend who recommended the blower mentioned that but didn't go into details. I wish all my small engines were so smooth and quiet (at least less high-end and more low-end freq).
