3500 miles???? You might want to get a used oil analysis to see if your oil change interval can be safely extended and save some money.
On my G37, my oil analysis tells me that 7,000 miles of hard use (11 dyno pulls, multiple runs down the drag strip) the oil is still performing as needed. Iron and aluminium is low and the BN is still > 4.
Just something to think about.
