Mazda Oil Filter Question

First, if you are aware of a particularly good oil filter of any make, I am sure we would all like to know about it and your reasons for recommending it.
Second, I've heard that some Mazda owners use Mazda brand oil filters. Mazda parts suppliers show two oil filters for the CX-5, but provide no other information than that shown below. So, which should we use?

CARTRIDGE, OIL FILTER
Part Number:
PY8W-14-302
Alternate Part Number(s):
1WPY-14-302, PY8W14302
or
CARTRIDGE, OIL FILTER
Part Number:
PE01-14-302B
Alternate Part Number(s):
1WPE-14-302, PE01-14-302, PE0114302B

Why are these filters listed as cartridge filters? Every one of these are screw on filters, not cartridges.

I use the OEM 1WPE-14-302 with no issues.

All you need is this:

1WPY-14-302 - for Turbo
1WPE-14-302 - for non Turbo.

Assuming you are in US.
 
I was looking at oil filter prices today, and it appears that the Japan filter is now less money than the Thai filter. But they are calling the Japan filter PE01-14-302B/302A. Not sure why there is a slash 302A in the description. Anyway a pack of 10 Thai filters is $123.99 and a pack of 10 Japan filters is $68.07 which seems too good a deal to be true:
Thai filters
Japan Filters

fake... ebay is full of them

real ones look like this, and do cost about $10 a filter

when it's too good to be true, it usually is!

they can say whatever they want... typical stealership scum
I can assure you the much better Denso made 1WPE filters are still very much available... while the value line filters might be "approved" by mazda, they're inferior in construction in every way... my dealer pushes the hell out of those and only keeps a couple of 1WPEs in stock, for warranty claim purposes and for the picky ones like me who will buy them (I don't: I imported a bunch of PE01s years ago)... they're basically half the price of the 1WPEs, especially now that with the tariffs the prices of the 1WPEs will eventually go up because they're made in thailand, and there's higher tariffs applied to thai stuff than japanese stuff (makes you wonder if mazda USA will go back to PE01s here once their stock runs out)... so this means, they can make much more money off oil changes, using cheap crap 0W20 tanker truck oil from wherever is cheapest... the value line used to be made in mexico, but if they changed to USA, it doesn't surprise me

if you don't care, like many typical car owners don't, the value line filters "work fine"... just don't count on them to do much good beyond 5000 miles, which is what most plebs change their oil at... if you're lazy/"ecological" like me (using the "flexible" oil change reminder setting) and try to get 7500 to 10000 miles between changes, then you'll want a better filter and oil (using the expensive legit mazda 0W20 with moly)

I have a turbo and run it hard so i change oil 3000-5000 max plus I do it myself and figure and my carbon footprint won’t amount to a hill of beans. If i hadn’t received a gift card from the dealership i would not have bought them. I still have 4 of the 1wpy filters. I will probably do an oil analysis this change and maybe use a value one next and compare them
 
you can "run it hard", but ultimately an oil analysis will tell you if you really need to do 3000 mile oil changes or not... I bet not... modern synthetic oils are very well made and durable, especially when ran in a car with an oil cooler, which the skyactiv turbo engines do have... the non-turbos don't, except for the ones in europe, mexico, and middle east

I'm looking into adding the factory oil cooler to my engine for better engine reliability and longer oil life, but it won't be cheap

no doubt I could easily go longer. I only run Pennzoil ultra platinum but it gives me the warm and fuzzies changing it early..been changing oil early since the 70's and never once had an oil related engine issue....I will say there is a visual quality difference between the Thailand 1wpy- and the USA PY8W filter.

you're free to spend your time and money however you want, since this is a "free" country lol... but I wouldn't change the oil that often because my time is precious and the money spent is 2 tanks of gas already... especially of the fact that I don't consider needlessly changing oil on a hot summer day, "therapeutic" lol

I used to be a believer in 3000 mile oil changes and "spark is spark" ("any spark plug works fine" / "don't waste your money on expensive spark plugs")... but I don't anymore... exponential advances in automotive technology in the past 25 years, let alone the past 50 years due to government mandates on fuel economy and emissions have essentially forced engineers/manufacturers to come out with better/more efficient products... used to be and still is, you can slap any mundane maintenance/ancillary part in your car and it wouldn't really make much difference... I know because I tried it in my very 90s beat up corolla beater before to try to eek 1MPG more out of it, and it didn't work... but now with modern auto/engine technologies, everything works like a symphony... use the right parts, and it's at the sweet spot and works in harmony... one seemingly inconsequential "dumb" part might make a difference in 1MPG, such as oil and spark plugs...

so rather than letting "old habits die hard", I kept an open mind over the years and continued to educate myself on these advancements, which all seem to be marketing ploys.... because there is certainly a lot of marketing fluff and hoopla out there... but research on reviews/anecdotes from others helps make informed purchase decisions, thanks to the interwebs lol

no regrets on this method... I've been able to be smarter with my time and money this way

unless you absolutely dog on your car on the track and cook the hell out of the oil, I'm betting 99% chances you won't need to change your oil in the short amount of hours or less than 3000 miles... every synthetic oil these days easily handles 5000 miles, even with spirited driving during the dog days of summer... 7500 is still a very safe figure, and from there to 10k, it depends on how/where you drive the car, plus oil analysis... in good, smooth running, clean engines like the skyactiv (at least non-turbo), most people's oil analyses show that 9k to 10k is pretty safe... no doubts to me that 10k is definitely safe with an oil cooler on a non-turbo skyactiv... maybe I'll take a sample and send it in when/if I ever get an oil cooler added lol

as for the filters, those new "USA" value line PE01/PY01 filters appears to be made by honeywell... the design looks too familiar lol... the old mexico made ones had lots of issues with leaks apparently, and people on the BITOG forums have said that the contact surface area of the gasket isn't as wide as the ones on the 1WPE/1WPY or good japanese PE01/PY01 filters, since those round o'rings squish down and spread out once pressure is applied on them... coupon or not, I would've walked away from buying those filters, get them elsewhere, or just buy WIX if I'm in a quick need for a filter and call it a day lol

on a side note, subaru america used to sell the japanese made filters off and on over the years and they last sold them about 17 years ago and switched to the honeywell ones... they're so much more crappier, and the price difference wasn't big back in the days... I haven't cared to look into those filters since then since I don't own a subaru, but I heard that during the "drought" years of selling non-japanese made filters, there were all sorts of issues with them... no doubt to me because of quality issues and the fact that subarus run higher oil pressures than most cars to begin with

.. in good, smooth running, clean engines like the skyactiv (at least non-turbo), most people's oil analyses show that 9k to 10k is pretty safe..,

. t that subarus run higher oil pressures than most cars to begin with
I'm not so sure I'd consider my Skyactive completely 'clean-running,;'. It seems like they have a fair amount of soot in the oil for the miles... possibly because they are direct-injected.
Subarus and Mazdas both are said to have higher oil pressures in normal operation. Maybe that's why there seems to be issues with those filters, too.
 
oil color is not a definitive indication of the oil condition... the fact that it turns dark is an indication that its detergents are doing its job... mine has about 7200 miles on its current oil (using legit mazda 0W20 with moly) and the dipstick color is brown, not black... on any old motor with the same miles on the oil, it'll be pretty black by now... the color does somewhat indicate though how clean running the engine is too

there's tons of data that shows that these engines are very gentle with the motor oil, so that makes the oil last a long time... this is compared to many (not all) other engines out there

GDI engines are, by nature, not clean running.
 
I wonder if deliveries from Partsouq (Dubai) are getting additional tax/duties next month. Buying in bulk for my Turbo wasn’t too bad early last year but not sure if thatll hold true soon.
