Diesel additive - yea or nay

[Hemlockusa]

If you have the change in your pocket, I believe it's good insurance. I don't think anyone REALLY KNOW'S. This fuel has just been required since the first of the year. We will all see the outcome five or six years from now. Again Don, I would do the additive, at least in your mind, your doing the best you can for your engine... mtcw John
