Auto oil is exceptionally durable and your engine gets used to a specific flavor. The only real complaint I have with my beauty is that RR got rid of the dip stick. I like to check the quality of my oil from time to time and the dip stick is my chosen method. Now there is some nebulous sensor that has specific criteria that must be met before I can simply check the level.
I do my own maintenance as well. I change mine every 15,000 kms (about once a year) Mine calls for regular 5w30 Castrol. I use Castrol Titanium Synthetic, Been doing it for 6 years and so far no engine problems from oil. Never uses a drop of oil and still feels slippery and fairly clean when I change it. I think the frequent changes recommended are unnecessary and wasteful.
