The Fit has better choices in the aftermarket, so it hasn't seen an OEM filter since its factory filter came off long ago.

I'll use an OEM filter when it makes sense.


It helps when you get a great deal on the OEM filter!

I'm basically in the same boat as you are. The Volt will get the OEM filter when it finally needs an oil change. The Ford gets a quality aftermarket filter included in the oil sales.

I will say in most cases you probably cannot go wrong with the OEM filter, you might be able to do a litter better, but you can definitely can do much worse.

And thanks again for the filters! I'm set for a long time!

And yes, one can do much worse than OEM. Seeing some of the no-name garbage out there for cars these days can be scary.

Thanks, Z06. It annoys me when zombie-like conformists assign God-like powers to manufacturers like Honda and Toyota. Yes, their engineers are very good, but they still make mistakes. Or their engineering decisions can be internally overriden by economic and marketing factors. This is how the business world operates. To clarify, I'm a Honda and Toyota owner and fan, not a hater.

OEM oil filters and fluids aren't always the best, but the best will often cost more. Hey, at least the Honda and Toyota air filters are excellent. They cut corners where they think nobody will notice on oil filters. I'm not sure who first called them "sieves." Was it river_rat? The Amsoil study above supports his conclusion. Nice catch, sayjac!

So what is the best PROVEN aftermarket filter that is readily available? Wix?
I always assumed that the aftermarkets were the best, but.....

Also does anyone know who makes the mazda filters? especially the Mazda Protege ones..

 

[Bruce T]

The Purolator PureOne is well regarded, but last I heard it had limited availability in Canada (that may have changed?). There are a number of Canadians and Mazda owners here who could answer these questions better than me.

Yes, I've never found P1s locally. Amazon isn't bad if you buy a years supply for a couple cars.

superchargedex,
I just put an M1-102 on my Son's '12 Mazda3 with the MZR, not sure what's in a Protege. I think they are a good filter and go on sale fairly regularly at CTC. It really depends on what your criteria for best is. Are you doing extended drains? Then you might want to stick to a higher end filter, M1 or Fram Ultra(or Synthetic or Extended Guard).

To me, if you stay away from the bottom of the line from any of the major brands you'll be ok. Take some time and look through the disected examples, lots of good information.

As for Mazda there's a good thread here but it's about V6 filters, I don't know if the same pertains to the I4 filters. It mentions Tokyo Roki, Mahle and Tennex (Mazda Canada?). The first two should be very good, the Tennex looked a little short on media to me.

Are you on torontomazda3?

I only buy American but my Ford uses Motorcraft 820S and my GM s use cartridge filters, Delco PF457G and 2129. The OEM filters seem to be the best for my applications.

and how did you determine they are the best for your applications?

Just a rebaged Fram. They will never see my engine
Purolator, or wix for me.



The OEM filter for the FB20 is made by Tokyo Roki in Japan now.

Good day! I have a 1994 Montero Gen2 3.5 liter. The filters from the stealer are around $6.00 they are made by Denso in Thailand.

The owners manual recommends changing oil every 7,500 miles and changing the filter every other oil change.

I never followed the recommendations. Just a personal decision. I guess you can say I spoil my truck. But I have had it for eighteen years in the garage

I use it for outdoor adventures......................

Probably the same way sciphi determined OEM was the best filter for his Cruze.

UMM! I would not recommend changing from using a real manufacturers oil filter, as they are nomally the best. It might be possible to use a high performance longlife filter and most of the major oil companies now make one, like Bosche, Mobil 1, WIX, Fram, Purolator and Amsoil. Those more expensive filters do offer a 99+% filtration rate that might be above OEM spec, BUT always DYOR and don't even think about using a non OEM air filter.

The snake oil chart needs more data, as some filters work better when new than old, BUT the reverse can be true of a high quality one and I would like to see the graph for 20,000 km. Not that I would buy a Japanese or Korean car anyway, as I am an old Volvo diesel for life chap.

The best information on several comes from relatively recent testing by Amsoil listed in the chart below. As you can see, not all the oem filters are created equally. The listed Honda A-02 is made by Fram and the Toyota most likely by Denso. The Toyota no endcap design efficiency shown confirms previous testing posted here by river_rat, that filters of that type aren't very efficient. And, that's being very kind.

On the plus side, the Motorcraft FL820S, the Mopar/Chrysler and the ACDelco tested quite well. In fact, the FL820S results finally gave Motorcraft users something they could point to positively, rather than the previous published spec of 80%>20um.

As for construction, the Honda A-02 is the typical Fram fiber end cap design and some ACDelco are ecore. So, it depends on the manufacturer.

Afaik, the Subaru oil filter pics posted here make it appear to be a Fram, similar looking to the Fram Honda A-02, but I've never seen an efficiency spec. Haven't seen much about the Mazda oil filter posted here, but there seems to be some different manufacturers as posted in this thread. A further google search of this site may provide more information.

Lastly, my comments are primarily referring to canister filters as shown below, not cartridge filters.

Aren't those certified tests done with new oil filters? How is that a snake oil chart?

LOL. Snake oil chart, would be in your opinion. The Amsoil data is tested in (ISO 4548-12) test spec, which is the accepted test method used to test oil filters today, even recently confirmed by a Fram tech rep here. And restating, the Toyota filter result confirms Toyota oil filter test results by river_rat, which is considered highly credible here.

Now, whether you accept the chart's data is up to you. Seems many here, including me, have given the results wide acceptance.

No reason to address the remainder of the unsubstantiated opinion attached to the quote.

Yep ... pretty hard to refute an official standardized test per an ISO test procedure.

If anyone wanted to get an oil filter tested per this ISO test, it would cost around $15,000 to have it done by an independent test laboratory.
