oil and oil filter
RevTech 20/50 oil in the winter and 25/60 in the summer. Motor Factory filter. RevTech trans and primary fluids as well.
DON'T FORGET TO BUY O-RINGS FOR ALL THREE PLUGS each change and it's a good idea to HAVE A SPARE DERBY COVER GASKET on hand as well...

I have cut open several oil filters and come to the conclusion OEM is often the best quality. FRAM sucks, don't know if they make them for Harleys but I would highly reccomend avoiding all FRAM oil filters for anything as the construction is lousy. I have cut open used FRAMs and found the filter element had a hole blown throug it! I have compared K&N to OEM H.D. and see no advantage other than the fact that the K&N has a hex on the end so you can use a normal wrench to remove/install it. The first time I changed my oil I could not remove the filter with my strap wrench so I had no choice but to purchase the H.D. oil filter tool for $10. The H.D. oil filter tool has a cut out that allows it to slip past a sensor that is in the way. The K&N is about $10 more than the H.D. so it is more cost effective to buy the H.D. filter wrench and use H.D. filters in the future.
I trust Mobil 1 products, time has proven Mobil 1 products are top performers so its Mobil 1 20w50 V-Twin formula for me. I get mine at O'riley autoparts
Don't forget to get a new o-ring for the oil plug when you pick up your filter. You will need it, the old one will be thrashed. If I remember correct a #013 o-ring from the hardware store will work as well.

I use the Harley filter on my bike because Napa doesn't stock their filter for Harley's in Canada. I use Napa filters in my car.

As others have posted the WIX and ACDelco filters are of similar quality and have a robust internal construction. Start cutting some old filters open (or use new ones if you have lots of money) and you'll be rather surprised at what you do, and do not find, in some very major brands. Google "Oil Filter Cutter" and you can find some very nice tools (Basically Can Openers for Oil Filters) for about $40.

All you guys that recommend picking up o-rings for each oil change, what are you doing that you need to replace them all the time? I've got 80,000 miles on my Duece and have changed the oil at 2,500 mile intervals and I've never replaced an o-ring.

Jjust because you change your own oil doesn't mean your going to lose your warranty (keep your receipts).

I suggest checking out the virgin oil analysis on that Lucas junk. It's got less additives than the extremely shitty syn 3 stuff.
And honestly guys. Why use motor oil in all three holes when oil companies make specific stuff for each.
