Thanks I have used this oil for about 17 years. I have a few friends that now use it. Best oil for 2 cycle. I had a back pack blower that my son filled with regular gas and ran the blower for about 1/2 tank of gas was gone. I added Opti-2 to the tank it never had a problem. Now that blower is about 18 years old and still running never changed anything but a plug.
