Hall, I use Klotz KL-300 (2 cycle motorcycle synthetic), mixed at 50:1, in my Brison 6.4, 5.8, Sachs 3.7, G-62 and G-38. I have never experienced any of the problem that you are talking about. I went over to the Klotz site and compaired the two oils and I can't find a clue as to what is causing the problem. You may have gotten into a bad batch. I've found Klotz to be very good oil.

My suggestion is to copy your first post (drag the mouse over it to highlight it and hit control C). Paste that into an e-mail to Klotz (control V) then report back to us if they reply.

Their e-mail address is: [email protected]
