rebreath, actually, this is a good forum (although I think it used to be great
) I for one am sensitive to use of this forum by spammers who have begun their first post with some thinly veiled attempt to suck members in with some phony, folksy claim. If this is not you because you are only guilty of being naive WRT one of these fuel additive claims, then my apologies.
If you want to keep an old MB running well and especially do the work yourself, there's lots of good info, but also an increasing amount of bad, so be careful.
