If you carefully read the service information that came with the vehicle, the premium care recommends a very frequent 3750 mile interval for oil and filter change. "Required" maintenance calls for changes at 7500 miles. I use a synthetic (Castrol Syntec full synthetic 5W-30)and change mine between 5000 and 7500. I changed it at 3500 using regular oil just to get rid of all the post production stuff that comes out of a new engine.

Opinions about oil are like belly buttons, everyone has one. Some get really emotional about it.

If you change your oil every 3500, yes, using synthetic would be a waste of money IMO.

In fact the Premium maintenance program is a waste of money. But then I am a cheapskate.
