Alternative Oil Filters ~ original poster wmax351
« on: September 23, 2013, 08:08:08 PM »
Mahle OC-91 (@ Amazon) is apparently the BMW OEM filter, sans logo.

Bosch 3330 and 72161 are the same filter, 3330 in mfg'd by Purolator in the US, under the Bosch brand. $3.50 a pop for either from rockauto.

From the list at IBMWR.org, with a few annotations from me (wmax351).

Sseven oil filter manufacturers for K100 spark plug and oil filter

From: Jonathan Hutchins <hutchins@kc.net>
Gathering together information to service my '85 K100, I found some details that didn't seem to be on the current parts list:
Oil Filter:
There was a lot of discussion on this ca '95-'96, with the engineering specs for the FRAM coming out as good or better than the BMW filter. Someone else pointed out that BMW does not manufacture their filters, but outsources.
Per Joe Senner:
   AMSOIL: ASF-57
   AC DELCO: PF-53
   FRAM: PH-3614, PH6063
   Hastings: 157A, LF157
   Motorcraft: FL-271, FL-793
   Purolator: FCO-201, PER-241
   Wix: 51348, 51785
Others including Rob Lentini have documented the Fram 3614, and I've used it; it's the only one I've tried.

Beemerboneyard sells a Mahle air filter which they say is the same as OEM for around $10 less than BMW's  ($33). 

edit: And I did a search for the Mahle part # (LX75) and found it on Amazon.com for $5 less than that!   Arrived yesterday and it is exactly like the BMW original.  With free shipping, I am a very happy biker.

I stopped using Fram 3614 when they started putting the grippy coating on them in the early 90's. It flakes off in the sump.  Fram 6063 is uncoated and unpainted, but harder to find and pricier.  Been using Delco pf-53's since

I've used the Quaker State QS3614 oil filter in my K75c for years now with no trouble.

I'm looking at that "Bosch 3330" wondering why the hell that rang a bell with me.

It finally clicked.

It's what almost all Toyota's 4cyl run. I quit using them (Bosch) because the anti drain back is not good and on a toyota that leads to a lot of start up rattle and timing chain noise since it uses oil pressure on the 22r motors to tension the timing chain. Went back to the toyota filters.

 No stickers on them to scrape off.

anti drain back valve would not be a problem in a K.  Unless the bike is upside down, then you probably have bigger problems.

I cringe when I hear of people using Fram filters.  I was a member of a fluid power engineering society back in the 80's and they did a report on filters for hydrauic and engine oil.  Fram was far and away the worst filter they tested out of about 40 or 50 brands.  Very inconsistant pressure relief action and poor filtration.  I admit, it was a long time ago, but I haven't heard anything in the meantime to indicate they are building better filters, and with so many alternatives I figure why take a chance.

Probably right with them being in the sumo and so low in the motor. On most toyota 4cyl they are halfway up the block and on their side. I'll be changing oil in the next couple days. I'll get some side by side shots.
