Re: 100:1 Mix
Check your local tool rental places. Most of them sell products along with their rental business. I buy my Opti-2 from a rental place and...they use it in all of their rental equipment, 2 and 4 cycle. Yes, there's an Opti-4 for you four stroke fans.
You can also call Opti. They'll tell you the closest dealer to you.
