Goin to be chaning the oil next week in all three holes. first time i Have done it. the dealer was too expensive last time i went in. who here uses the K&N oil filters, or do you use the Harley brand? what types of oil (brands) do you guy like and who much goes where? i have the manual, just getting options

i have a 2008 EGUC with 30,000 miles

Thanks

 

Good question! It's about time someone asked this... anybody?

 

It's about the only thing i get from the dealer. I have read some place that the HD filters are 5 micron
and could never find that info on the aftermarket filters.
might be crap but i don't know.

 

Just curious, cause you have more than 500 posts... you haven't seen this horse beaten to death?

 

Clicker: Actually, I have even more posts than the OP, and I haven't seen this discussed much. Maybe it was before my time in the forum.

About all I've seen is that Harley oil filters for the twin-cams are, for some reason, rated at 5 microns, and the earlier engine filters rated less (and 5 micron supposedly could cause a problem for evolution and earlier engines by being overly restrictive on oil flow).

K&N's are convenient because of the integral removal nut, and are supposedly of high quality. I do know that K&N is not very forthcoming about the the micron rating for its oil filters.

I haven't heard why it is especially important that the twin-cams have 5 micron Harley oil filters. I suspect it's because Harley sells them...but I don't know that for sure.

What I do wonder about is (though I think I know the answer); is the micron rating of the filter for the twin-cams as important as merely changing the oil at a reasonable and protective interval?

 

I will second you on that one Krusty1 .

 

Oh man... you're killin' me bro!

 

That's not my intent!

I guess every new generation of HDForum users has to learn the same lessons, over and over. I guess I need to remember this when I'm an 'old hand' here. All I know is, that I've gotten some very good advice from the forum.

 

I'm sorry man, I really thought your response was "tongue in cheek." In all seriousness, do a search or check the oil thread in the main forum. There's is a lot of really good info covering more than you probably want to know. Lots of opinions; enough to wanna make you pull your hair out. But, the general rule of thumb is, a quality filter, quality oil, syn or dino, and stayin' on top of the maintenance intervals and you'll be okay.
I run amsoil. 20-50 in the crankcase, 75/140 in the trans and 10/40 in the chaincase. There are many suitable fluids, maybe better than what I run, but you'll have to decide for yourself. Lemme know if you need anything else bro.

 

I use the Harley Chrome oil filter,only because I can't find a good qualty aftermarket Chrome one !!!
