I just checked the valve clearances for the first time on my 2008 Suzuki SV650S with 37,000 km. Most oil changes have been with Rotella T4 15W40 with 2,000 to 6,000 km OCIs, every 1-2 years. The engine has been running Mobil Delvac 1300 15W40 for the past 5,500 km. The Delvac only has 800 ppm phosphorus, so I'll be switching back to Rotella to be safe.
Photos aren't great, but I'm pretty impressed with how clean everything is (at least inside the engine).
