When"s the best time to change oil on a new mustang? I have a 2015 Mustang GT Premimum package - Competetion Orange. I have about 2500 miles on it?

 

the dealership should have sent you a memo by now, 7K for your first oil change, thats the break in oil,I use mobil 1 full synthetic and Ill change at 15k, now ay 14500, with full synthetic it should be @ 8k per oil change

 

Consult your owners manual, and follow it.
