Bosch ST3300 Oil Filter - Fits 2016 but won't work for 2017??

Here is a video showing the internals of the Mazda OEM oil filter. As the video shows, it lacks an anti-drain back valve and it lacks complete coverage so the oil doesn't always get filtered. That leaves me a little uneasy . There are better filters out there. Remember, Mazda does NOT make its own oil filters, it outsources to the cheapest manufacturer.

This isn't accurate, I know the guy in the video states that, but he's unfortunately mistaken. The bypass valve forms a seal on the center tube at the dome end, this ensures that oil will have two routes of entry back into the engine; through the filter media or if the bypass valve opens.

Use the Mazda filter with confidence.
 
Well, I returned the Bosch filter and bought the Mobil 1 extended performance filter (M1-108A). My Mazda dealer only had the VALUE oil filter, not the Japanese version.

I did my first oil change @ 1,500 miles. It's just my habit for the past 30 years of vehicle ownership to empty the oil in a new engine before 2,000 miles since a new motor has a lot of break in metals and machining debris circulating. GM's were notorious for this. The new Corvettes mandated an oil change after 500 miles since the oil filter would get clogged with silicone and other materials. Plus the oil was sitting in the vehicle since it was built in Japan back in August 2017, almost 7 months ago.

The stupid drain plug gasket was stuck to the drain plug since it was painted back at the factory. Took a while to finally free it off of the drain plug. The factory oil filter was the Japanese Mazda version, which is a very nice filter. It looked identical to the Mobil1 except for a blue valve at the bottom of the Mobil1 filter. BITOG highly recommended Mobil 1 extended performance.

I used Mazda Moly oil in the quart bottles. Oil is 1/2 way on the dipstick, just like the factory fill was. I won't do the next oil change until 6,000 miles from now.
 
I prefer the Allen head drain plug and Mazda does also. Much less likely to over-tighten and mess up the oil pan. I use a torque wrench to tighten so no problem for me. Ed
 
Good choice on the Mobil filter and early oil change. If you look at my UOAs there's definitely some elevated wear metals from the factory, which is normal. I would highly recommend that you change the drain plug with a hex head, makes it much less likely to strip out. https://www.amazon.com/dp/ (commissions earned)

Thanks. I noticed the 2017+ takes more oil than the 2016 did. Is that true?

The 2016 took around 4.4 quarts while the 2017+ takes around 4.8 quarts, almost 5 quarts.

I made sure to use the torque wrench as well. Can't really go wrong there.

4.4qts for the 2l and 4.8qts for the 2.5l is stated for both '16 and '17 manuals. I have the 2.5l and use a 5qt jug and call it a day. The extra .2qts is 6.4oz, the engine will never know.

I put 5 qts in my 2014. Manual called for 4.8, but 5 seemed to be the good spot for it.

Honda specifically said in the owner's manual that don't change the factory-filled engine oil early and use the standard OCI for the first oil change. It's because Honda uses special break-in oil from factory and you don't want to drain it too early. Good factory oil filter should catch those damaging metal shavings with no worries.

As for hex head drain plug, unless you can find one with larger round flange to cover aluminum washer, which all hex head drain plugs do from other automakers, I wouldn't recommend it.

Yeah, OEM drain plug has no magnetic at the tip. I confirmed that when I had an oil change several days ago. It's black paint.

However after seeing your comparison picture which makes me believe we should keep the OEM Allen drain plug. OEM Allen drain has larger flange to make sure evenly deforming the aluminum washer with specified torque. 19mm hex drain plug actually applies more force to the aluminum washer with smaller flange area contacting the washer using the same torque, hence the inner blurred edge of your aluminum washer. My used washer doesn't show any sign of that. OEM Allen plug also has non-threaded extension (painted in black) helping us to guide the plug into the drain hole and prevent possible thread stripping during initial turn. OEM plug also has longer length of thread area which may be necessary to match the thread length of the drain hole.
I agree with yrwei52, my OEM aluminum washer doesn't look like that either (red arrow indicates uneven load spread from the smaller flange hex bolt), I'll stick with the larger flange allen bolt that came with the car


 
The “special “ break in oil for Honda is no longer made by Idemitsu which was a high Moly oil. For the US market it’s made by Exxon Mobil and the moly content has been reduced. Moly comes in various forms so going by ppm is not enough.

Changing the factory fill is a personal decision. If the owner struggles between wanting to change and Honda saying no, then just buy the Honda oil and change it. Most oils have moly in them anyway.

Rabbit trail for a second here, if you'll indulge me...

Is it pronounced moly (like the name Molly), or moly (mole-y)???

Good thing I don't drive a Honda ;)

Seriously though, while this is true of Honda. Mazda's factory fill isn't a break-in blend. It's plain Jane high Moly 0w20 that you can purchase from any Mazda dealership or in the form of Idemitsu from a parts supplier. Honda does (did?) this because the factory fill is different than Honda 0w20 that you purchase from the dealer.

We are talking about the Mazda engine, not the Honda. There's nothing wrong with changing the factory fill on the Mazda, as it's just Mazda Moly, what I put back into it.

Why bring up Honda in the conversation when it has nothing to do with Mazda? Plus Honda 1.5T engines blow up. Go to the Honda CRV websites and see all the problems they are having with the 1.5T so even the factory oil fill and factory filter can't stop a bad engine design that causes it to blow up the motor.
 
Got this response from Mobil 1 tech:

The Mobil 1 M1-108A oil filter has a by-pass valve setting of 11-17 psid. The micron rating for the filter media is 30 micron at 99 plus % efficient.
 
No problem. I figured it was a quality filter as BITOG and other sites reviewed it highly. At 30 microns that is really good.
On the contrary 30 micron rating on filter efficiency is pretty bad. No wonder Mobil 1 website chose not to list filter efficiency rating for its Mobil 1 Extended Performance oil filters including M1-108A! See my post here for more details.
 
The guy in video apparently doesn't know too much about Mazda SkyActiv-G engines. He cut open a Thailand-made 1WPE-14-302 Mazda OEM filter but kept wondering why there's no oil left inside the filter, and why he didn't see an anti-drainback valve! The oil was all gone because there's no ADBV. And the oil filter for SA-G is mounted baseplate up hence it doesn't need ADBV! Further, we can see an o-ring on the side of by-pass valve touching center core of the filtering media, how is it possible it would be leaking unfiltered oil commented by the guy? This's a perfect example of false information easily be found on the Internet!

Here are several links of info from Bob is the Oil Guy on all 3 Mazda OEM filters been cut open with pictures:

Mazda PE01-14-302 Factory Filter CUT OPEN

Mazda 1WPE-14-302 Filter 5k mi - Mystery Bypass!

Mazda PE01-14-302A-MV used cut open 7,779 miles

All of them looked excellent after many thousand miles of service including the Mexican made one. So Lbear, don't bother looking for unknown aftermarket oil filters, just go get OEM. Yeah, Mazda did go cheap discontinued Japanese oil filter and outsourced to other manufacturers. But oil filters made by those manufacturers still have to meet the required specifications given by Mazda. You can always get the Denso one if you ask for it at dealer's parts department with 1WPE-14-302 part number. They can always order one for you if they don't have it in stock. Remember even the Mexican made OEM oil filter is excellent according to the cut-open result.

BTW, 1WPE-14-302 from Thailand is most likely made by Denso as it's physically different in size comparing to PE01-14-302A from Japan made by Tokyo Roki. Some claim PE01-14-302A-MV from Mexico is made by Wix but someone had cut open both Mazda "Value Products" PE01-14-302A-MV and Wix 57002 and found they're definitely different.

Good info here, yrwei52, as always. The only reason I call the MV filter cheaper is the wrench stamping on top, it's inconsistent as hell. Been through a half dozen of these things already and sometimes the filter wrench will fit and sometimes it won't. I've cut a few open myself and the insides fit the bill. I've always used OEM, they're fairly inexpensive so I don't understand why people think they're getting a better deal with aftermarkets. And yes, having no ADBV makes sense, thing is upside down so where do people think the oil is going to go?
