Praise the Lord! I want to rate it better than excellent. We are a commercial landscape company and run 2 and 4 stroke equipment all day. We would keep regular gas and mixed gas on the truck for the different motors. About twice a year, or more, someone would mess up and put straight gas in the 2 stroke and seize the engine. Now there is one tank of gas with the Opti 2 and it goes in all our equipment, 2 and 4 stroke. No more mistakes and all the engine wear and tear has been enormously reduced! Amen.
