I have a 1982 Johnson outboard motor and started a few years ago using your oil having read about it in a magazine. Well up in this part of the country our big fish is the walleye and normally to get these you have to back troll to make a slow presentation. With all other oils that I have used before I had trouble with the engine running rough. When you had to speed it up it would smoke and finally would smooth itself out. With Opti-2 I can go for hours and hours and never have this problem, and when I do decide to have to move faster I have no big cloud of smoke after me. The engine runs like a million bucks with you oil. Best regards, PEP
