Just changed mine for the first time at 7500 miles, dealer was shocked that the oil was "... clean as a whistle." I think I'll stick to the service manual at 7500/8000 as well and use reg oil. I've ran synthetics in imports for years that turn high RPMs (8000-9000) but think the grunt motors are fine with the regular stuff.
