Sorry if this is a redundant post, I have tried the search function to no avail. Get a lot of posts, but none answer my question. Is anybody using additives? What kind and how frequent? Every/every other fill up? what advantages do you all see? I purchased a case of the Amsoil additive and when that was done I purched some FPPF Total Power and Cetane +8 from Kennedy. So far, the Cedtane +8 seems to give me some +MPG. Thanks.
