x2 on the 15k. I've used M1 oil filters for 2x 7,500 mile intervals in my 2007 Civic and the UOA after 15k miles on the filter came back looking just as good as after 7,500 miles (it didn't show that the filter was loaded and went into bypass mode, thus allowing unfiltered oil to flow through the engine)
