Oil Filter

I want to switch to Amsoil in my Dyna. Do I use the H-D filter or does Amsoil make one for their oil?

You can probably use either - amsoil makes a filter. No idea which one is better.

They do sell one, but the HD one is fine.

The amsoil filter number for most all twin cams is
EaOM134 for black
EaOM134C for Chrome

http://www.amsoil.com/catalog.aspx?Code=EAOM134C-EA

I say most all because there might be some special applications I dont know about. Most every twin cam I have looked up use the above number. What bike do ya have?

*edit* I looked at your posts and looks like you have a 2005 FXDC, the above number is correct for your bike.

Thanks for the reply's. I just wanted to make sure that Amsoil didn't require a different micron size in the filter.

Harley's filter has a bypass built in. I don't know if the Amsoil filter does.

My Amsoil dealer sells them for about the same cost as HD.

For now, I'm using HD since I bought 4 when I bought my bike (all gone now).

Next time I order oil (which is soon) I'm going to switch to Amsoil filters for ease of not having to go to the dealer and it's a one stop shop since I get my oil from one guy.

I don't know if one is better than the other, but I know Amsoil makes quality oil so I assume their filters are equal or superior to HD...and I think superior since I know the oil from HD is mid-grade level at best, for premium prices.

As far as one oil needing a special filter, the oil doesn't care what you use.

If you order the amsoil filters order there oil filter wrench as the one that fits on the end of a harley filter will not work with it. We made ours work with a thin pcs of rubber jammed in the wrench circle to take up space but the way the harley filter wrench is made if you have the solid aluminum oneit will not work it will slip on the amsoil one like its to big. We used them for about a year as we were ordering everything by the case's from amsoil but then got a better deal locally on HD filters so went back to them. From what i read also about the two filters the HD one had the better micron ratting vs the amsoil. I still only use amsoil in all 3 holes but also use the HD filter.

Also found out something i didn't know and that is that the 20w 50 motocycle oil has the additive in it for the engine so if you have an engine issue and harley test for the additive it will be there. But you can use the amsoil standard 20w 50 as in the primary as it is the exact same oil just doens't have the engine additive and is $2 bucks cheaper per quart if you using it in the primary.

I still just order the amsoil 20 w 50 by the case usually but if you are picking it up at a local shop it would save you a cpl bucks.
