This will be my 8th new car and one thing the others had in common was not to drive at a steady speed for any great length of time. Example: don't put the cruise on and drive at 65mph. for 100 miles but to break the motor in at varing speeds, stop and go etc... . I've always taken it easy the first 100 miles then after that go for it the next 400 to 500 miles before taking a long road trip.
Change the oil after the first 1000 miles then every 3-5000 intervals based on manufacturer recomendations.
I don't BABY my vehicles but I do maintain them. I can't wait to see how my Solstice performs on the winding rolling 25 mile drive to work thru the country, my only concern there are the Deer I see because there isn't any traffic to deal with ( Thank you Lord for that).
