Mazda V6 oil filter and extra oil question
 

Okay,

I know from other posts, the FAQ, and mazda friends that I can run a Mazda V6 oil filter on my 2002.5 Pro for the additional filter surface area.

Can someone who has the numbers handy tell me the part number for the regular (2.0 4cyl) and V6 oil filters?

Also - anyone with the correct ID# for other brands, feel free to chime in. I personally like WIX and NAPA gold (by Wix) filters. It'd be nice to have a simple cross reference table in the FAQ. Maybe we can start a list here and get it added.

Finally -

How much extra oil have you guys been adding when switching over to the larger filter? I figure an even 4qts would be fine for the larger filter.

Thanks for any product / part numbers you can provide.

Hi,

I'm totally new here, but i have been driving Mazda since i've my license...

ok, I think u can use the "Fram" oil filter for I4 #6067??? I forgot about that number, but U can also interchange it with the Mazda V6 "fram" brand for V6 with #7073 , Try to look into the MX-3 section, the I4 use the same filter as P5, and the MX-3 V6 uses the same diameter, but a larger filter !!

try checking the oil level with the dip stick, then u'll kno whow much more u gotta put in.. ! i think it's less than 2 tea spoon.. ! :D

V6 FILTER
 

Normally the engine calls for a PN# B6Y2-14-302 (I4), but you can use G6Y0-14-302A (V6) for a little more oil volume and filter volume.

or just go to the mazda dealer and ask for the 'V6 oil filter', there is only ONE V6 filter model for ALL Mazda cars :)

You will need to add a bit more oil than with the standard 4 cylinder filter, but not a whole lot more. Just check the dipstick as you fill up until it's at 'F' on the stick :)

on the 1.8L I added 3.5 quarts with the V6 filter.

hmmm ...
 

I don't know if the V6 one has the 'check valve' ... the factory filter I took off of my 2002 P5 has part# B631-14-302, and it has a solid raised hump on the bottom inside that has another smaller raised bump on it. Isn't that the 'valve'? It certainly seems more substantial like it could actually have some kind of mechanism there. The V6 filter (part# G6Y0-14-302A) has a raised flat hump on the bottom inside, with a long hollow tube attached to that. Maybe the hump that the hollow tube is attached to is the 'valve' there too? Not to mention they have different sized and number of holes along the rim and inside walls. The factory one was the Roki one (made in Japan), and the V6 one was the Tennex one (made in USA). Maybe the Tennex I4 one has the hollow tube in it like the Tennex V6 one? And maybe the Roki V6 would look more like the Roki I4?

Re: hmmm ...
 

both filters have a check valve
both filters satisfy filtering and flow requirements from mazda

Will switching to the bigger filter really help anything? :confused:

IN THEORY a bigger filter will have larger filtering surface, which means each filtering area would filter LESS amount of oil compare to a smaller filter for the same mileage used. Put it in another way, the oil will be more 'spread out' across the larger filtering surface area, hence THEORETICALLY filter at optimum level for a longer period of time...

That's what I thought as well, but I just wanted to make sure.
