Oil Filter Comparison from $6 - $23 what do you get?
 

Hey All,

Was sorting through my garage and realized I had 4 different types of oil filters lying around for my RX7. Figured I would try to share a comparison of them for anyone interested in what you get for your money. I am in no way suggesting which is best. Decide that for yourselves. Just putting the info out here.

Apologies for the crappy internal photos, I really struggled to get the camera to focus.

FYI, I decided to ignore shipping cost in my table because no one orders a single oil filter. Usually I just add them to an existing purchase and they ship in the same box for free. Especially the ones I get from Japan.

Any questions let me know, otherwise here is the information and the photos:

Prices are in USD, weight in grams and perforation numbers/size are eyballed estimates....I am not counting them :lol:

Group Shot. Note RE-A has orange color visible and the FEED filter has 8 holes vs 6.

FEED weight 260g

No Name Brand - Smallest, lowest number of perforations. Lowest overall area of perforations

OEM - Smallest, but highest number of perforations. Medium overall total area of perforations


https://cimg1.ibsrv.net/gimg/www.rx7...5afc7cdb44.jpg
RE Amemiya - Largest, medium number of perforations. Equal largest overall area of perforations with FEED. Magnet in centre felt strong.

FEED - Meduim size perforations but with a large number of perforations. Equal largest overall area of perforations with RE_A. Has two additional perforations in the base compared to all others (8 vs 6). Could not locate the magnet. But as this is so much heavier than the others perhaps is is built into the filter elsewhere.

Good comparison. If you ever have the time, it'd be awesome if when you're done using these you put them away to leak out and dry off for a while and maybe re weigh them and then cut them open. I'd be curious to see where the magnet(s) in the FEED are.

Any way, good read. Thanks for putting this together.

Good point! I can for sure cut them open once I have used them and report back......

May be a while though.....I have managed less than 1,000km since I got the car lol!

Cool! if you can please post some pictures in this thread!

I will see if I can figure out how to cut it open tonight. Maybe a can opener? haha. never pulled one apart.

I recon a hacksaw will slice through it no problem. That or a dremel with a cut off wheel.

About $40 for an oil filter opening tool -


Kind of like a can opener/pipe cutter in design.

I've always run FC oil filters since they are physically larger and have more filtering material. They are harder to get in and out due to the larger size.

Really, just running a quality oil filter and not a super cheapie is the way to go. I've run Purolator filters for years, they are commonly available at any parts store, reasonably priced, and work and fit great.

The Wix / NAPA Gold filters are also very good.

wix is the only filter with full specs published.

there are basically three types of filter.

a "normal" filter filters everything.

a long life filter will filter less stuff, a filter can only hold a certain amount of stuff before it starts bypassing, and when it does that its not filtering anything. so a long life filter will not filter as well, but this lets it last longer.

a filter for synthetic oil, usually the valve changes materials, sometime the filter media does too.

Wix publishes all of this data, everyone else is spotty to non-existant

I like the Purolator PL14610, it should fit more filter media inside since it's a little longer than the FD RX-7 filter but not quite as tough to install as the FC RX-7 filter. One of the vehicle applications is a 1994 Mazda 626, so it's easy to find the part number if you're searching through a paper catalog at a parts shop. It has the same bypass pressure as the one intended for the FD RX-7. I can't take credit for finding it, someone else posted the idea either here or on other RX7 forums / websites.

@j9fd3s, I just spent some time reading the Wix website and really is nice. Do you use anything aside from their recommended filter for the FD?

nope!

oh and the Japanese short Mazda filter is B6Y1-14-302A, available at any US Mazda dealer, list price is $9.49.

there is a US made short filter, B6Y2-14-302-P1 its cheaper, and white, no other info

the "tall" Mazda filter is JEY0-14-302A not available through Mazda USA. Mazda USA sells a G6Y0-14-302-P1, its US made, white.

I recall people mentioning the 929 filter as well. My understanding is the SBG pedestal allows some extra room for the larger filters.

Oil Filter Comparison Study - GM Truck Central

Here's a pretty definitive comparison for oil filters readily available in the US. I got this link from from bobistheoilguy's website.


Also, I've been running an oil filter for a 2000 Mazda 626 with a V6 forever. They fit fine and are a little bigger (taller) than our stock ones.
