I've been doing a little searching on here an haven't found anything on this yet.

Has anyone found a replacement oil filter for the GT that's for another vehicle application, same thread pitch/size, same diameter, but just longer?

I'm getting ready to hit another 4K miles and I've got to go out today to get another Purolator PureOne filter, but would like to have a longer one as the stocker is so damn small...

Let me know if any of you know off hand the thread pitch and diameter of the stock oil filter so I can hunt for a larger replacement.

Thanks!

Thanks for your reply, however, that's something that I wouldn't take anywhere near an engine. It has no drainback setup in it, plus I just wouldn't trust a SS mesh to filter engine oil well.

Basically what I'm looking for is a longer oil filter, doesn't matter what brand because I can always cross reference it into a Purolator, that will screw into the filter stud of the 6G72 and make a perfect seal.

The stock type filters are only about 4-5", I was wanting something around 7" for more filtering area.

PS, you always seem to be answering in my threads ;)

Well, I have been in the situation before where geting an answer quickly was required. I may not have all the right answers but I try to give my thoughts on the matter so the user/reader has something to go off of, immediately. Hopefully, others will respond, in time, and have a better oil filter option for you. :yesway:

That TOGA filter is the only "non standard" filter that I have seen discussed. Thats the only reason I mentioned it. I ended up not ordering that filter. Although I am still tempted.... I can't believe they would sell a filter like that, and at that price, if it didn't actually work. Maybe I will be the guinea pig :)

A little update here. I just got off the phone with a Purolator rep and got the specs on thier PureONE filter for the GT.

The filter stud diameter and pitch is 20mmX1.5 respectively. The diameter of the filter itself is 3.15" and it is 2.95" long. Pretty short eh? Shorter than I even guessed.

So, all I need to do now is find a filter that's 20mmX1.5 and a diameter of 3.15", but just longer, maybe 7"??

The part number for the PureONE for the GT is PL14459 for reference here.

I got ahold of a Fram rep (cringe) they are going to be mailing me a product reference guide so I can compare the I.D. of the oil filter and I.D. of the o-ring to see which ones are longer and what I will need to replace the short, stock oil filter.

Once I have secured the fram part number, I can just cross reference that number to any oil filter brand of my choice ;).

good luck with reference guide-sounds like fun and that is quite small...the one on my quad is only slightly smaller for 660cc's

Nice thinking, the Fram catalog (if it has that info) should be a perfect way to compare.

A slightly (very slight) diameter change may be OK as well, from what I remember (changed mine a week or so ago) our gasket isn't really up to the edge of the flat area at all. Although, a larger diameter would have to be damned sure that there's no corrosion or pitting where a gasket might go out too. Maybe not such a great idea...

Glad someone is doing this, I've thought about sitting in a store and opening boxes but just never have.

Uh, why do you feel that you need a larger oil filter? The stocker does an adequate job so long as you keep up with the owner's manual for filter changes. It sounds like you're tilting at windmills here.
 
#10 ·
It's not needed by a mile. But it would be nice especially if it didn't cost much more if any at all.

Little more filtering area, little less restriction, little more oil capacity for the engine, little less likely to ever plug and bypass, little longer it'll last between changes if you run your oil forever, and so on. A little of this and little of that. Nothing big but it wouldn't be the first thing we've all done that didn't make a big difference.

Couldn't have said it better myself ;).




I'm a little confused with the whole discussion: why do you feel you need a larger filter? If you are that worried about your filter limiting oil flow from the filter clogging, or feel that your filter does not completely filter the oil, why not just change the filter more often? Or lower the mileage from 3000 to 2000 miles between changes. Another thought, try a synthetic oil filter, they are designed to filter out smaller particles.

Please read the above quote. Why spend more money on more oil changes if it's not needed when you have the peace of mind or a larger filter with more surface area. I just don't like the idea of ~5 quarts of oil filtering through such a small oil filter for 4000 miles. Sure I could change the filter earlier, but why do that if you can get a slightly larger one?





I'll check the Wix book at work tomorrow. The other thing you have to pay attention to is the micron filtration level. Even though the filter is taller doesnt mean that it will filter to the same micron level as the shorter one, if so there is no bennofit. Again, I'll check the Wix book tomorrow to see what I find.
I research the filtering capabilities of the filter if I find one that I like. Thanks for bringing that up!





Another option to think about is a magnet for the filter. I have one on mine, and you'd be surprised how much more metal junk is visible when you dump the filter. It's a $30 part and will last forever.
Also think about a magnetic oil pan plug. It'll look all fuzzy from the metal filings stuck to it.

Could you give me a link to these if you have one? Thanks!






For Wix filters the stock one is a 51334 which is a little under 3.5" tall, the 51568 is a taller version with the same gasket od and id but a little smaller overall od, but its got another inch of height. Thats the tallest one I could find that met the gasket demensions

I appreciate that very much! I'll cross reference that number to the cataloug I just got in on the Fram filters.

Sorry for taking so long to respond, I must have forgot to subscribe to the thread :(

Got a link for this thing or any additional info? Is it a sandwich type adapter or just a magnet you slap on the side of the filter? I'm pretty sure my 3G came with a magnetic oil drain plug, but maybe the previous owner installed it.

UPDATE​


According the to the Fram 2006 Product Reference Catalog, the specs on the stock replacement oil filter are as follows:

Part #: PH3593A

Canister dimensions

Outer diameter: 3.02"

Inner diameter: 20mmX1.5mm

Height: 3.39"

Gasket Specs.

Usage: Base

Outer diameter: 2.42"

Inner diameter: 2.13"

Thickness: .2"



I have found a damn good match so far, one catch though. The application lists it under Case, John Deere, Kohler, Komatsu, Melroe Bobcat, Takeuchi, Thermo King, Yanmar. So, it looks to be for diesel engines...

Does anyone know of any major differences between the general design of a diesel application oil filter versus a gasoline application oil filter???

Here are the specs:

Part #: PH5046

Canister dimensions

Outer diameter: 3.02"

Inner diameter: 20mmX1.5MM

HEIGHT: 4.94"

Gasket Specs.

Usage: Base

Outer diameter: 2.42"

Inner diameter: 2.13"

Thickness: .2"

What do you guys think?

This filter from Fram cross references to many other brands, some of the better ones being: Purolator (the cross reference # for this one gave me part #: L24458, which has been superceeded by L14459, the EXACT SAME FILTER FOR THE ECLIPSE GT, so I know these will fit just by that little piece of info. Now onto more details on some of the filters.), Wix, Mobil, and Napa.

Wix # 51318 specs are as follows:
Type: Full-flow
Height: 4.803"
O.D. of the can: 3.673"
20mmx1.5mm
Bypass valve setting: 16 psi
Anti drainback valve included.
Burst pressure: 280 psi
Max flow: 8-10 GPM
Nominal Micron rating: 13
Gasket O.D: 2.538"
Gasket I.D.: 2.224"
Gasket Thickness: .200"


In summary of this one, it seems way too wide, but the rest matches... Weird.

UPDATE

I'll be heading to the parts stores when I get off of work today to compare some of these filters myself, that way I can find the applications they go on, and start cross referencing them to other brands that I prefer to use.

I spent a week (several years ago) at an oil analysis class (centered mostly around large equipment like what you'd find in power plants, though we did of course talk cars on occasion), and all the instructors for it considered the Purolator Pure-1 and Mobil-1 filters to be the best, at least as far as what was commonly found at the parts stores. These guys had done lots of testing. That said, I haven't tested any myself, but since their livelihood was centered around this stuff I just go with the info and make sure to get one of those two brands as well. If that helps any.

Off the top, I'll also say that a diesel filter might be as good or better than one for gas engines. Newer diesels anyways use oil pressure (10's of thousands of psi) to fire the injectors, and oil cleanliness for the injectors is more citical than for the rest of the engine. I'm sure this changes from one application to another, so there's no real bet as to what you're getting, but - a diesel filter is worth considering or at least finding more info on.

Also, "beta rating" if you can get it is the best way to compare filters. It doesn't just give the (theoretical) smallest size particale that a filter can capture, but also gives the percentage of those particles that will be captured (for example, a filter that captures 99% of 10 micron particles on the first pass is probably a better filter than one that captures 10% of 8 micron particles on the first pass, even though 8 micron sounds better at a glance than 10 micron - if my explanation makes any sense).

Yes, I know exactly what you're talking about ;).

Purolator PureONE is actually what I do use, but this last time I just switched back to the regular Puraltor after seeing how densly packed the pleats are in the PureONE compared to the regular one. I would believe that the PureONE could actually restrict flow as it's so densly packed. I'm sure it filters great though!

This is another reason why I'm putting the Neodymium magnets on the regular Purolator. I'm also considering buying some slightly stronger ones for the tranny and oil pan...

UPDATE

After standing in the parts store for over an hour after work today, comparing and cross referencing oil filters between every major name brand, I'm come to a conclusion...

The old Purolator that cross referenced to the larger Fram listed a couple posts up is no longer produced. It has been superceeded by the L14459, which so happens the be the oil filter used for the GT :rant2:

All other crossed referenced oil filters to the larger Fram are indeed the same dimensions as the Purolator L14459.

I give up in short. :mecry2:

I'm not using a crappy Fram oil filter on my car, sorry, not going to happen.

It so happens that I couldn't even find the damn Fram filter mentioned above at the parts store either, I'd have to go to a dealership that spealizes in tractors to get them.

i too like the pureone filter. i do extended drains and notice that after about 5-6 months and 3000-5000 miles the oil comes out dark in color, but clear. i can shine a light through the stream as it flows and see no opacity in it whatso ever. i do not see this with the valvoline filters we use on customer cars at 3000 mile intervals. this says to me that the pureone is filtering out more shit than the valvoline filters which is a good thing. i'd contemplated getting a filter adapter to turn the filter 90 deg so it points down on my car, lessing the chance of drainback, making it easier to prime on changes, and allowing me to run a longer filter, but i dont feel its necessary.

i DO wonder sometimes about some of these cars i see which have filters no bigger than a shotglass it seems. i wonder how that tiny filter is going to not fill up and bypass should they go a little over on a change.

if you really want a bigger filter, you could get a perma-cool remote filter mount. Summit has one for about $50 or so i think, that adapts right up to the GT block and can run a PH8A sized filter that is about twice the size of the stock GT filter. im running the single relocator with a K&N on my swap, they do have a dual one as well.

Permacool kit
 
#31 ·
hmm i like that. dual filters would be nice for extended intervals. run a high volume filter in series with a very dense filter, get good filtration at all engine rpsm, just watch the pressure drop.
