This may be a dumb question, but as an oil information newbie I have been using as well had the previous owner, MC FL820S filters on my 05 Vic (2v 4.6) with 3,000mi synthetic changes (usu PP, M1) (save me the ridicule!) up until currently at 61,000. I have learned from a few people that the FL820s, while having a very good silicone anti-drainback valve, has some crummy filtering media that sometimes tears. Because of this, I plan on changing over to NAPA Gold filters in the future... but the question is.. has the "damage" already been done? Is there really a benefit to doing this at this stage in the game?
You engine will be fine. Doing 3k intervals is very short and even if you had a filter failure, I doubt any damage has occurred.
Wix Gold is a solid filter choice.
There are no cons when upgrading to a better filter. It's better.
But not necessarily any real benefit either trying to find the "best".
The term "better/best" is vague. In comparison to the 820s, better is any filter than does not have a continuing history of failure.
A Supertech filter is better than an 820s in that aspect. I personally don't care much for the combo valve that the ST2 has, but will still use them (and am using one right now on brother in laws truck).
Whom to believe... That's easy... Who's actually cut those filters open after use ??
Now the Motorcraft FL 500s and FL 400s are great... Those two filters always look perfect after use and being cut open.
Yup, I had enough discussions on a few F150 forums about the issues with the 820s.
Even after posting multiple pics of failures, there were some that were just to stubborn to get it. "I never had a problem with one" is all they say, and asked if they ever cut one open, usually get "I don't need to", or "I cut one open 15 years ago".
There are a few here that are like that as well.
I now just provide info if someone asks and leave the thread. I really don't care what others use. I know what I will and won't use based on my research, using facts I find, not my feelings.
I do agree the amount of "damage" that occurs during a normal OCI of a filter that tears is most likely negligible.
The fact is, you buy a filter to, well, filter. Having continual proof of the media failures just is not acceptable, despite the minimal chances of damage in a clean engine. When you have other options (even cheaper options), why use the one with issues?
