It means everything is hunky dory for ME, now doesn't it?
What happens with youse guys is your own bidness. Personally, I think extended OCIs are nonsense, engines are stupid, and manufacturer-recommended OCIs have marketing geared toward wearing out the car faster built into such recommendations. My oil was remarkably clean draining after 3k, and the ADBV made swapping the filter a snap. I also think extended OCIs are partly responsible for the tears popping up. There MAY be a problem with the filters, but as I said, my own experience will form my opinion. I remain unconvinced the problem is as widespread as some here claim. I'm, reading a LOT of FUD in this thread alone.
A longer OCI will have you at the engine shop or the dealer's showroom faster than a 3K OCI. Seems penny wise and pound foolish to me. For me, a 3k OCI means three oil changes per year. Maybe four. Not expensive.
Filter failure or not, it's not like there's any engine damage to behold.
Modern engines are pretty [censored] bulletproof and with adequate OCIs, nearly everything else will break before the engine does. And even if by some chance there is engine failure, there's a lot of other reasons before it comes down to purely filter and oil.
Even my neighbor across the street has been running his Acura TL and Subaru B9 Tribeca on conventional oil for 10k+ (even past the oil life monitor reading, gasp!) for years, and the engines haven't failed yet.
There's a lot of milling on oil, filters, and intervals but not many stories on engine failures. And of the engine failures I have seen, the majority are due to stupidity (never changing oil, poor maintenance, etc.)
3k changes not expensive? Depends on who you ask. Bad for the environment? Definitely. Worth the peace of mind? Your choice.
Manufacturers aren't conspiring to design a maintenance schedule that will have your car break down after the warranty period. That's just bad practice and not in their interest. If the car is that bad, you'd be smart to not buy from that company again. They would lose you as a customer and get a bad rap, which above all else is what they don't want.
Either way this topic fascinates me, hence why I'm here.
