Not all oil filter are created EQUAL! - Page 4

I see a coil spring in the Porsche filter which means it is not a Fram as they use a leaf spring. The Porsche filter looks like a good filter to tell you the truth. I would probably say the Porsche filters size is the correct one but either way I would just use the mahle one as it looks better.

thx - that's very interesting

I hope P AG is not using us as outsourcing for cheap crappy products...

think I'll stick with the Mahle oil filter (& Cisco routers, Qualcomm chip designs, etc.)

The "oil drop" logo leads me to believe it is a Champion Labs filter. Also the LS128 is a Champ International P/N.

See: www.champlabs.com/products/oilfilters.html

They are the manufacture of the K&N and Mobil M1, but they are also the purveyor of the Ecore design. The jury is still out on the Ecore and I have read of a couple catostrophic failures in larger engines using 20W50.

As with any of filter you can not really tell what media is used and general claims by manufactures are useless to determine what is in a particular filter.

You can see the Posche filter has the bypass valve in the dome which looks identical to the M1 and K&N while OC-54 has it in the base which is preferred. The slight difference in size is inconsequential relative to size of the media without knowing internal construction.

I haven't found anything on Mahle media and Champ is all over the map from M1 to K&N to Ecore. So who knows what is in the Porsche filter.

What I did find on a different filter study was the M1 (with synthtic blend media) probably had the best filteration for partical size but flow rate relatively low while K&N (phenolic-resin impregnated cellulose) had some of highest flow rate.

FYI, the best I have heard of is AC Delco 'UltraGuard Gold' but only available for Corvette; 7um and high flow using glass/fiber.
BTW, I read Champ makes the Ultraguard for Delco.

"What's In Your Filter" - keep looking and watching.

I figure with the M1 filter I have on there now, Porsche engines run so high an RPM anyway that oil pressure is pretty high regardless.

Formerly Steve Wilkinson · 11-10-2006, 10:12 AM

Drove a Maserati GranSport at Road Atlanta awhile ago and noticed that the oil pressure was pegged at the very top of the gauge (which as I remember was the right side, actually). I thought something was wrong, so I came into the pits, they said no, that's normal.

Over the years I've become quite fond of the WIX filters! Napa filters are made by WIX and these are some of the best filters for my money!

interesting link, comparing all the major brands!

Pep Boys actually used to sell the German Purolator filter, was heavily constructed. They don't anymore. I found the Mobil1 filters for any application sometimes had metal bits inside the threaded hole and a dirty film on the base too. I assume it's left over from the manufacturing process. Try this, wipe your finger or better a clean white cloth on the base of any brand and see what you get. Ditto for the threaded hole. Sometimes the filter's are dirty, often metal bits are found in the threaded hole, not so for Mahle. I always check any filter before installing to ensure no crap was left over from manufacturing.

glenncof · 11-10-2006, 03:06 PM

The minimopar study is really old and probably should be ignored. Only a recent study on a PARTICULAR filter configuration could be considered useful.

http://minimopar.knizefamily.net/oilfilters.html

Things are constantly changing like Mann & Bosch agreeing to buy the Puraltor operation from Arvin Meritor Corp (see www.arvinmeritor.com). 'low and behold !', the Bosch filter is a Puralator PureONE (Bosch P/N 4310) in another of my applications.

I bought a Fram air filter once for my 911, it was made by Mann.

Most brands don't do their own manufacturing, they buy from someone else. It's entirely possible to have several manufactures across a single brand. Do you think a filter manufacture build all filter types ?(hint, no) Filter salesguys say they sell to other brands.

I'll stop here...I don't want to get started...

Wil Ferch · 11-11-2006, 05:21 AM

Sidebar...peterfrans' pics are very telling....

In the past, you could have bought a Porsche filter from the dealer or the OC-54 elsewhere..they were pretty much identical. Look at the pics again. The "new" Porsche filter has suffix ".01"...is made in America, and is definitely a cheaper unit, no spring, etc. I used to insist on the proper ".00" suffix until they ran out.....yep, Porsche cheapened the filters for us "old Porsche" drivers !

OC-54 for me !!

Be glad you don't own a Boxster. I'm about the change the oiil in ours this morning, and I always marvel that the filter is simply a little lawnmower-size paper element. The can is plastic and is permanant--a replaceable-element filter.

glenncof · 07:18 AM

BUT WHO KNOWS ?

Maybe Porsche USA is using the Delco Ultraguard media (with mesh screen insert) in the robust Champ can ? Doesn't a Porsche deserve the same great filtration of a Corvette ?

Naw, I'm just a dumb consumer....

I almost forgot. This is the company that specifies 15,000 mile oil changes and gets 600 miles/qt fleet average.

Formerly Steve Wilkinson · 11-11-2006, 08:27 AM

For the Boxster, believe it or not, they also specify an oil change but NO filter change every 15,000 miles. The $12 filter gets changed every $30,000 miles. Wouldn't want to overburden the wallets of poor Boxster owners, and after all, the filter is a good eight inches from the oil-drain plug...

Steve@Rennsport · 11-11-2006, 08:55 AM

You have to admit that Porsche's recommendations are REALLY good for their burgeoning parts business and now a major contributor to their bottom line.

No conflicts of interest there, nossir,.....not a chance.

- Welll.... 1st, this might be an env'l consideration - the filter is hard to recycle and full of toxic waste.

2nd - and perhaps more importantly - unless it clogs, the filter will be more efficient (work better) if you do NOT change it. All filters are more efficient if they have some filtrate on the media than if they are new.

glenncof · 11-11-2006, 12:42 PM

randyweb,

You got it. Environmental considerations.

Don't polute with the filters...just scrap the car and get a new one !

porsche930dude · porsche930dude's Garage

anybody know what company makes Trust filters. I get them for free so i use them on all my vehicles but not the porsche for that i use mahle. Also ill probrobly use synthetic on my next change. What viscosity of mobil 1 is recommended for a stock 82 3.0 in ny climate?

Correct. For one of our ford trucks, I had bought a K&N and a Mobil1 filter. They looked identical, aside from the nut on the bottom of the K&N.

"just scrap the car and get a new one"

OK - I actually have a tidbit on this: Somebody (EDF or NRDC - one fo the think tank type enviro groups that employ scientists) actually did some fact finding on the issue. They found that about 1/3 of the lifteim pollution from a the typical car was from the manufacture of the car itself. That's a lot. Obviously, it isn't based on [1] long-lived cars like the 911 or Volvos, and doesn't consider [2] local or regional effects based on watersheds or air basins (e.g. do I care if they pollute Korea to make my Kia?), but it is still an large and interesting factoid to drop on the next Bordeaux sipping guy at a aparty who tells you to sell your old 911 and get a Prius.

(Just to fend off any comments - I like the Prius - great car, not a fun one but a great one).

sorry for bringing to life an old thread but I could not find a more current discussion - over the weekend I received an email from our host that German made Purolator Micronic PC260's (930-107-764-03-OEM) are now available - any comments would be appreciated.

how many quarts of oil for a 1980 SC oil change?
