Could be a one-size (psi) fits all approach or perhaps the synth media has superior flow properties while capturing extremely low micron particles.
I quit the 10k mile oil changes a while back over the concern of having to top off the oil frequently when using Mobil 1 Extended Performance oil. Since then, I felt there was no need to pay $10 for a M1-110A. I found one thread on the web, but its ancient...
Either that, or if you use either the Honda filter or a high grade filter from a major manufacturer then it doesn't much matter which one choose - and the concern that some have expressed over bypass valve specs ends up as nothing more than making a mountain out of a molehill.
I think it's a great discussion for those who DIY and buy aftermarket parts. If there is a possibility that an aftermarket oil filter can keep oil cleaner for longer, I want to know. I'm sure that I'm not the only one. What good is an oil filter if the bypass valve stays open all of the time? That could be causing engine wear. It's a moot point for you because you use dealership services. You will continue to use dealership services even if something else is proved to be a little better, like your use of semi synthetic oil for example.
Both Wix and Wix XP have a 8-11 psi BPV rating.
Quotes are from a discussion on the high bypass setting on some Subaru motors: “OE Subaru and WIX are the only oil filters currently on the market that have the Subaru-spec bypass valve rating (OE 23 psi vs. more typical 10-12 psi).” (Fram has been mentioned to make the blue OE Subaru filter).
I hear it, but I don't know that I completely believe it. If this were true, wouldn't there be different BPV settings between the two Wix filters with different media? Why is the Purolator Boss that is made with synthetic fibers, said to be ok for use on our Honda with a 14-18 psi BPV rating? It would seem to me that this would cause the oil to pass through the filter for a longer oil change interval, versus any Wix filter with it's wimpy bypass setting. By logic, would it not be best to use a filter with the highest BPV setting so long as the vehicle can safely handle it? Maybe this is how these filters can go 10k + before needing replacing.
If the performance of the Honda oil filter - or semi-synthetic oil - is already sufficient, isn't choosing some aftermarket product that might be a little better a moot point?
Have you used synthetic-blend motor oil in your Pilot, or not?
Supposedly, the bypass valve can also open on cold starts before the oil has warmed up.
How cold must it be for the pressure relief valve to open before the oil flows?And supposedly a major benefit of using synthetic oil during winter months is due to its enhanced flow even in low temperatures ….
Well thats your supposedly statement about bypass valves. I'd reckoned it's impossible to associate this with a specific temperature as there may be multiple variables: internal clearances, grade of oil, size of oil pump, health of oil pump, rate of warm up and age of engine components, strength of oil filter canister etc etc....
Which vehicle is that for?
