I've had the car almost four months ('11 g37x), still only at 1900 miles.

Should I bring it in for the first oil change or wait til 3000 miles?

 

Take her in and remove the first batch of oil that withstood the break-in. Just my opinion - I took mine in at 1000 and even did the tranny oil flush. If not for mechanical reasons, then for peace of mind. Only hurts the wallet!

 

if it's at 11month, go ahead and schedule for the 1st oil change, you don't have to wait until 3000miles..
