Re: 100:1 Mix
I bought the 12 oz bottle from our local independant hardware store that has been selling Opti for years and their equipment rental division has been using it in all their two stroke equipment for ten years. They told me to mix it 100-1. I looked on the label and it said mix contents (12oz) with 10 gallons of gas. That didn't compute. I called the company that makes it Interlube International 1-360-332-2132 in Blaine, WA about 15 miles from here.
They said Yes 100-1 has always been the correct mix but some packaging says 12oz in 10 gallons OR 1.2 oz per gallon and some packaging has left off the "or 1.2 oz per gallon. The product is the same as it has always been.
I dug around in my garage and found a old 12oz bottle and it had the "or 1.2 oz per gallon" on it.
I am using it in my Grubee 66 at 100-1 and run the heck out of it and it keeps running better and better as I get miles on it. I have about 300 miles on it so far.
