On the "MOAB" thing, are you talking about a specific website where folks like to spell it that way? Or where are you seeing folks do that? Is it just within the Nissan community, or more globally?
If we're thinking of the some of the same places, it's been a big pet peeve of mine ... I think for some, it stems from their only exposure to the town coming through
G.O.N.E. Moab. The logo for the event for a while has been:
... which is great as far as logos go, and I like it a lot. But folks, I think, see it and for whatever reason, let the formatting creep into their own lexicon without thinking about how the name of a town/region is not part of the larger acronym.
But if you're seeing that done outside of referencing that particular event, or worse, outside of a few isolated cases within the "Nissan Community"; then I've got nothin' to help explain it and I'd be equally bewildered.
Anyway ... hopefully the Seafoam helps you out a bit. Am I remembering correctly that there's a bit of a recommendation floating around, that one should only put it into the oil just before a change is due? Or more specifically: that if you want to Seafoam the oil, you should change it soon after?
