was it an aftermarket filter or a Mazda value-line filter? there's a difference. while we may not like the value-line stuff on this forum, they are still OEM parts.Some Mazda dealers are selling aftermarket parts of questionable quality under the name of Mazda Value. They charge OEM prices for these.
The reason I know this is I bought a cabin and engine air filter for self install from my Mazda dealer. I ended up getting this crud.
Just checked my invoice and noticed they also installed a Mazda Value oil filter with my oil change.
Needless to say, I am not at all happy. I will not return to the dealer [John Hine Mazda in San Diego] for any type of servicing.
For the prices they charge I want true OEM parts. If I wanted aftermarket parts I would have gone to jiffy lube.
On the contrary, Mazda dealers will use cheaper Value Products “MV” maintenance parts almost all the time unless you ask for more expensive genuine maintenance parts and are willing to pay the price difference.I think this is marketing to benefit the dealers. If they do the replacement work they can install and charge for the higher priced item, but parts department can sell the lower priced product for people who are cost sensitive or independent mechanic shops...
I am going to buy one of each, slice them open and see just how equal they are.was it an aftermarket filter or a Mazda value-line filter? there's a difference. while we may not like the value-line stuff on this forum, they are still OEM parts.
when I was buying oil filters from the parts counter at the dealership i work at, the guy asked why i wanted the more expensive ones since they all work the same
Actually at least 3 different Mazda OEM oil filters had been cut open before at Bob is the Oil Guy:I am going to buy one of each, slice them open and see just how equal they are.
BTW, I sent an email to Mazda HQ letting them know of this issue. If you cannot trust a Mazda dealer to install Genuine Mazda OEM parts, who can you trust?
Thanks for the links. This makes me feel better.Actually at least 3 different Mazda OEM oil filters had been cut open before at Bob is the Oil Guy:
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
Mazda Skyactiv PE01-14-302A-MV Cut Open
You’re welcome to cut open these OEM oil filters and give us your opinion. But based on the reports from BITOG we can tell MV oil filter is the worst among 3. I can tell the quality of the MV oil filter is not up to the standard of the other 2 because it comes with non-greased and different flat gasket and without paper box.
Yes, I believe there’s no free lunch, and “Value Products” must have been cut some corners somewhere to achieve the object of lower cost. I wouldn’t use “Value Products” just to save a couple of bucks if I want a high quality OEM parts.Thanks for the links. This makes me feel better.
But I still feel the dealer has an obligation to disclose they are installing a lower cost "value" part. And/or give you the option to get the factory OEM version.
As for the MV engine air filter, when you compare the two there are obvious differences in the construction. This morning I pulled out the MV one and installed the factory OEM version.
For those who feel they are true equivalents... good for you. Nothing wrong with that.
For me, I just want the same as was originally installed at the factory. That's all.
I probably should have been able to blow out the junk out of it.Your old filter looks very clean. Did you blow all the junk out of it? I see what you mean about the housing vs the MV.
MAZDA Value filters are approved by MAZDA and are good filters for the full 7,500/year oil change. Those who say they are 3d party and not good are misinformed. Ed
Can you elaborate this leak situation? My guess is the leak is from MV oil filter’s flat-surfaced gasket instead of o-ring type gasket used on Tokyo Roki Japanese filter and Denso Thai filter.I've used about 5 of these in past years, have had 3 of them leak on me, won't use them again. I specifically ask for the Thailand made ones at the dealer, not a whole lot more money than the MV ones and the filter wrench fits better..
Don't really know why, but after a few thousand miles there would always be a few drips on the bottom of the filter, only one that ever gave me any trouble. Might have something to do with the stamping. Also, the oil filter wrench wouldn't fit on properly, again, inconsistencies in the metal stamping.Can you elaborate this leak situation?

And Denso Thai oil filter is pre-greased on the o-ring type gasket (so as the Tokyo Roki Japanese filter), not on the MV flat-surfaced gasket.Most likely. I noticed the o-ring on the Thai filter helps self squeeze and put a very nice and tight seal when tightened.
