I received an oil change at a local lube shop at 3,200 miles. I just received a letter from my dealer saying that my first 3,600 mile oil change is free. I have a little over 4,000 miles. Should I take the car in for another one since its free? What do you guys think? I've heard people say that during the break in period it isnt good to change the oil often. I figured the break in period is over for me...what do you guys think? Should I get that oil change? Thanks in advance.
