BTW, I have 2.5 bottles of the Stihl ultra in 1 gallon of gas... that 2.6oz per bottle... so roughly 6.3 oz of oil to 128 oz of gas... which should be 20:1 by my math..... its been mixed thoroughly several times....

I'm not getting the goop on the plane that I see in other pictures... there are a couple flecks.. but nothing major. should I be worried?
