I have every intention of continuing to use the P1 'as vehicle manufacturer recommended', just as the OR statement on the website, says in black and white.
I've already used P1's to the 1year Honda max twice, ~7k each time. The dissected PL14610's looked great, and I continue to use with confidence.
Again, it's unfortunate and a disservice the PRO rep(s) is/are choosing to ignore the 'complete' website statement in favor of the 3k/3m CYA half statement.
Also, the PRO rep also told me on the phone that ALL filters should changed at the same 3k/3m interval, and that it was only that synthetic oil that was allowing for slightly longer oci's. That's when I knew he was not authoritative and seemingly just trying to sell more filters. I then emailed a Purolator engineer directly, but received no response.
Fwiw, as a mini experiment, I'm currently running a Puro made Bosch D+ and intend to run it two OCI's as Honda recommended in a 3.0L Accord. I do so with confidence.
