Just curious about this. I've always changed the filter when I change my oil. But of course, the MM has the A maintenance and the B maintenance. What's up with Honda thinking the filter only needs to be changed every other cycle?

That's almost 12,000 on a filter. Is there some engineering data that suggests filters don't need to be changed as often as we do them, much like we've moved away from 3,000 mile OCIs?

I just find the "every the filter every other oil change" to be rather unusual.

Yes, there is. I still change my filter at each oil change out of habit even though it isn't necessary. Engines stay so much cleaner these days with tighter tolerances, better oils, and better fuels.

zroger73, is this becoming standard practice on vehicles over the last 10 or so years.....oil filter changed every other oil change? Also wondering if it's a Honda thing given their engine background or if it was everybody.

This may be sort of a moot question, anyway. My daughter's 2012 Corolla uses synthetic and has a 10k mile OCI. D Not sure many manufacturers will recommend a filter change every other OCI with intervals creeping upward, but who knows.

Well, of course, as long as you're paying for it, why not change the filter for you? They're nice folks. :)

Honda has been doing it that way for at least 10 years - that's how long it's been since I bought a Honda Accord that recommended to replace the filter only at every other oil change. Same with the Civic and the other two Ridgelines I've bought since then. Right off hand, I don't know what other manufacturers (if any) do this.

All filters become more efficient at trapping contaminants as they age. The older the filter, the smaller the particles it will trap as the filter media becomes "loaded". Essentially, the older your filter is the better it will protect the engine...UNTIL THE FILTER BECOMES SO LOADED THAT EITHER THE MEDIA RUPTURES (rare) OR THE INTERNAL BYPASS VALVE OPENS (common) and you end up with little to NO filtration.

Which is why changing the filter for every OCI is what I do and will continue to do. Yes, the filter does technically become more efficient when it's been in use for a little while, but there's a fine line between filtration capability and providing proper oil flow. As far as I'm concerned, an oil filter has an extremely important job and it should not be overlooked. It's an inexpensive part and doesn't take much more time to change. It just makes sense to do it.

Agreed. Apparently, extended OCIs and filter changes at every other OC have been around a lot longer than I previously thought. Since my last post, I stumbled across this scanned brochure for a 1976 Monte Carlo like the one my grandparents bought new. I was surprised to see 7,500-mile oil change intervals with 15,000-miles filter intervals advertised. My grandfather was a mechanic and meticulously maintained his vehicles. He always changed the oil and filter every 3,000 miles and so did I until my first Honda in 2006. Now, I just do it when the vehicle tells me to (except I still change my filter every time).
