What I saw/see after very detailed explanation including start and finish odometer readings documenting the 12000+ miles fci early on in the thread, was a questioning of the OP asking if was 10800 miles less than reported. I consider that if not an insult to the OP then at least a questioning of his integrity. So I have no difficulty understanding the OP's reaction, and based on some other follow up posts, others agreed.
What makes it more odd imo, is if one has unequivocally stated they won't use Purolator filters numerous times, why not just let it go and move on. Combine that with the third degree, again it's easy for me to understand the OP's reaction.
Bottom line, the OP posted a positive Classic anecdote here and majority replies have been respectful and grateful for his efforts.
