Guys, I am sorry but I can't give you much on the filter.
I just started using the Amsoil filter a 1000 miles ago.

I went over to Amsoil oil and filter in all 3 holes. I can get the oil for just about half the
price of SYN3, witch is $8.49 a quart[sm=forgetit.gif] The Harley oil and filter must
of been doing some good for all these miles
