I'm going to buy this stuff in a local auto parts store, so Suzuki branded products won't be available. On my R6, Mobil-1 oil and filter was always recommended, so I guess I'll stick with that? If anyone can tell me the part number of the filter they recommend, it would make it easier. I'm going with synthetic oil, but which grade? I believe I used 10W-50(??) on my R6. Thanks!
