This has been floating around for some time now. I hope the numbers are still good. Please double check before using any of these filters.
Harley davidson oil filter part number 63731-99A conversion to:
Wix 5 micron for twincam 57148 black @ O'reillys
Wix 5 micron for twincam 57348 chrome@ O'reillys
Napa 5 micron for twincam PS7148 black
Napa 5 micron for twincam PS7348 Chrome
Mobil1 M1-102 (not sure of the micron rating, but this is what I'm running on mine right now)

Sorry guys I'm lazy and on my phone at work so the search function kinda stinks. First oil change for myself is what I meant to say. I'm at 8500 miles and the previous owner last changed at 3000 miles.

The owners manual will tell you what weight of oil you should be using. If you don't have an owners manual... get one! You should also get a service manual too if you're gonna be working on your bike. Amsoil, Mobile 1, Redline and Royal Purple are all good oils.

Is the MoCo recommending that, or do you simply have a good Indy or Dealer?
The MoCo spent 10 years telling customers that synthetic oil wasn't necessary in Harley's, and some dealers even said it could hurt your bike. Then, some marketing guru figured that HD could enhance the bottom line if they embraced synthetic oil. So they came out with a cheap syn blend, slapped the bar and shield on it, marked it up 20 times and told people to use it in all three holes. Funny stuff indeed!
It's one thing to do this when you ride a bike with a unit construction engine and have no choice. It's another thing when you have a choice.
Again... Right product for the right application.

Auto 15W50 in the motor...formula plus in the primary and tranny...no use in paying more for V-twin oil when it doesn't share the primary like a metric......
Napa 15w50 4.99 a quart.... Amsoil, Mibil 1 Vtwin is fine also...

Use whatever your comfortable with.
I use rotella in the primary,motul 10w-60 in the engine right now and red line shockproof in the tranny.
