For years I used a Napa Gold 1101. I went to buy one last week and the are discontinued. The guy said they put 4 of them in the trash about a month ago :'(. He crossed it to another number. When he said it was $35 I never wrote the number down. At Advance Auto I found a Purolator L30007 for $8.39 ea. It fits the unit just fine. I am all for a good filter but I believe the $35 filter from Napa is a product of supply and demand and will probably be the next discontinued filter.

I found a Fram C252 is one that's easy to find. Hers the specs and a lot of cross reference #'s

Interesting thread on the effect of oil filter brand vs engine oil pressure.

I've been using the Napa Gold 1101 for some time now. Haven't checked on local availability lately.
Another good thread on cork vs rubber seal on the Napa 1101.

I've got low oil pressure and oil leaks on my OC-3. Next oil change I'll put a little more thought into which filter I use.

I just searched the NAPA site and that don't show the 1101, but do have an 1105 it costs $19... about double what you can find others for.
Napa 1107 is what I'm using.
Just checked NAPA site and 1107 doesn't come up
I have been using a NAPA 1105 on my OC3 and OC46, it is the same filter as my Oliver Super 55 diesel uses.
The Baldwin PT302 would work as well. Here is a Baldwin cross reference to other brands.

Crap! my 1107 is no longer available! >:(
Evidently the Napa replacement is the 1010 according to some discussion over at Yesterday's Tractor

Installed a WIX 57011 from O'Reilly Auto Parts on my HG 42 yesterday. Works just fine.
