just kinda want to get a take as what to use for my 98 single cam big twin
just really dont see much but the hd brands and would think there are others out there .. thanks for your feedback ..

 

Some auto parts stores stock a black oil filter for the H-D's.
Make sure that you geta filter for the Evolution engine, NOT the Twin Cam.

As for oils, I've always (mostly for warranty) H-D products.
My main road bike is 2000 Ultra so it's always used the regular (non-synthetic) 20w-50w.

Other oil suppliers have similar weight but make sure whatever you buy is designated for a V-Twin, air cooled engine.
My buddy uses Mobil-1 in his H-D trike.

Some of the newer bikes use the "three hole" oil but I'm old fashioned and I use the H-D products as recommended in the owners manual with the exception of my transmission which is an aftermarket Baker DD6 and they recommend Red Line for it.

H-D also makes a special oil drain funnel/hose for removing the oil filter but you'll still need a low drain pan and plenty of rags/towels for clean up.

Also, you will need to "o" rings for the drain plugs and some teflon plumbers tape for the primary case plug.

 

I use either Drag Specialties or Rev-Tec primary fluid and for engine oil I use an automotive 20-50 race oil, usually Valvoline VR-1 not the synthetic. All of the oils I mentioned are easily found and reasonably priced.
