As a manager of a large hardware store rental department, I am so impressed with Opti-2. We use it in everything we have including: weed eaters, demolition saws, chain saws, hedge trimmers, any of our 2 cycle products. We have every brand from Husqvarna, Stihl, Kawasaki and many more. It is always easy to mix the correct mixture for great performance. Mechanically, our profits have increased due to less burnt up pistons because of too weak of a mixture and we have far less fouled spark plugs to deal with from too strong of a mix.
GREAT JOB! IT IS A GREAT PRODUCT AND EASY TO USE!!!!!
