i dont see how spending $45 on an oil change is an issue... thats a pretty good price to pay and unless you drive like crazy youre only spending that $45 every 4-6 months. With an OEM oil filter being $10 and an aftermarket being about $8, you save 2 dollars every 4ish months or $6 per year

and youre running a wix air filter for what benefit? to spend $25 instead of $27 for an oem? this saves you $2 every 1-1.5 years depending your driving habits.

if the small amount of cost difference between OEM maintenance items and off brands is an issue for you, maybe look into making some extra cash to cover the costs. if your saving about $8 per year with after market items, you can make this money back somewhat easily to afford the OEM stuff. one idea off of the top of my head would be to offer one your neighbors a once per year lawn mowing service. if you mowed one lawn per year at a rate of $8 per mow, this would come out to... $8! - - - enough to maintain your car with OEM filters for 1 year. if you dont feel like doing that much work, you could try cost cutting in your personal life. heres another idea off the top of my head... buy 1 less pair of underwear over a 1 year span, this will save some serious cash, you might have enough left over to buy some lucky girl a burger from the dollar menu.

IIRC the oil pressure max's out at 125 psi around 5000 rpm, using a 30 weight.
IOW, after 5k rpm the oil pump is in bypass.

Isn't it the filter media that creates the pressure difference and the amount of media that determines the service interval, IOW how much dirt it can hold without blocking?
If that is true - I'm asking - a bigger filter just gives you a longer service interval, not better filtration and/or less oil pressure drop by default.
Another filter media might give better filtration at the cost of flow and a higher pressure drop, more media would make no difference?

I'm not an oil filter engineer, so I'm just sticking with the OEM PCX.

Btw.. the aftermarket car part industry thrives on people that are sure their car needs performance upgrades, marketing playes a huge role here.
Most claims are not proven, are statistic noise at best.

I run Mobil 1 and OEM filter also. It maybe $45, which is about a tank of gas, for you now but the filter runs two oil intervals. Good price over the life of it.

I look at cost closely too, 166K on a 06, I'm dropping oil every other month and go still go with OEM.

Also request a discount from the dealer, doesn't hurt to ask, I get one and only because I asked if they price match.

The filter media does create the pressure differential as do other parts of the filter design, as the filter traps more contaminants the greater the pressure differential. So if you start off with over twice the filter media as well as a bigger filter can(compared to stock) you have less pressure differential with the same amount of oil going though the filter. The oil goes though the larger filter at a slower speed so the filter has a better chance to trap more contaminants as compared to a smaller filter where the "same" amount of oil has to go though the filter at a greater speed and with a larger pressure differential. I have never seen a larger filter hold less contaminants than a smaller filter and the larger filter does give you a longer service interval, first by filtering the oil better and second by allowing your vehicle to take more oil(6qt's > 5qt's).
You could use a better filter media(smaller micron rating)with a larger filter and still supply your engine with 100% of the oil it needs, but you would not want to go overboard without knowing the gallons/minute the filter will flow @ whatever psi your vehicle needs.

I put 3k to 4k miles a month on my "S" and on my next oil change I'll get a UOA after 150% as shown by the engine oil life indicator. I just changed the oil and filter so it will take me 3 to 4 months but we have some drives planed so I will post the results when I get them.

I have never said that the stock filter(or any other) was bad, I just think I can do better than Honda because I don't have to worry what it cost me since I buy 6 at a time not 60,000.

I appreciate the civil discussion we have had on this because I know how fast this could have degraded as many post have in the past when its about GOD forgive oil or filters.

Yikes! Re-use a filter? Really?

$45 is about what I spent, to the penny, for oil & filter. Sure, compared to a new engine, it's a trifle but a 62.5% cost increase over 24 months from the exact same parts counter?

Don't know about the term reuse as the filter is suppose to run two oil intervals as recommend in my manual. No issues with 166K on her.

Running the Mobil 1 Syn, I also run the maintenance minder to 1000 miles over, which is about a little over a week in terms of my driving.

It won't bypass. The bypass is based on pressure differential, not total pressure.
