Here's an interesting discovery/problem. I have used Purolator 14612 filters on my 2008 for the last 50,000 miles (and my other bikes for circa 200,000 miles or more). Ten days ago, I changed the oil prior to riding in the Mason Dixon 20/20 rally. When I got back, I found I had an 'oil leak', which I traced to the damn oil filter. When I had changed it the other day, it didn't seem quite right - you know, you feel the gasket make contact, then give it a little additional part turn. I didn't get that feel at that time. Anyway, I changed the filter again, thinking I had over tightened it and distorted it the last time or something. Nope - same problem with the new filter.
It appears Purolator has either changed the depth of the filter (outside of gasket to the metal part of the filter body), or I got two bad ones (one 'regular service' filter and one 'extra special, cost three bucks more' filter). When I spin the filter on, I get no 'gasket contact' feel, so there is no 'just a little more' turn.
I just went and bought a Wix filter from O'Reilly auto, and measured the depth - the Wix has about 3-4 mm more room before the filter would bottom out on the nut on the 'oil filter cartridge bolt' that the filter screws onto. New filter goes on as it should.
Weird.
And no, the cartridge bolt hasn't backed out of the crankcase (it's on with lotsa torque from the factory) over the last 108,000 miles, so it has to be the filters..
