Seems like most guys are using synth. What about the change intervals? Has there been a general consensus about how often it needs to be changed while on synth oil versus regular oil?
Whatever the dealership has for the first 4000, 8000, 12000, 16000, 20000 km. And then Amsoil 0W-30 @ 12 month drain intervals with a filter change @ 6 months.
