Fram 3614 should work for you as well and they are available everywhere. These are longer and thus increase both oil capacity and cooling surface area. Not to mention that you open yourself up to more choices in terms of media. I've been running the Tough Guard 3614 on a Briggs V-Twin for eight seasons now. That's about 240 hours of run time in my case. Lately I've been running them for two seasons or 60 hours. I believe that a commercial operator could easily run these for 200 hours since they are rated for 15,000 miles in automotive applications. Fifteen thousand miles at an average 35 MPH comes out to well over 400 hours in an automotive application.
