So I have been reading on the veloster forums trying to learn about this motor and I have read that some guys are changing their oil after the car hit 1k and says it runs smoother with the better oil in it. I am curious if we should do the same thing to ours or just wait till we hit the 3k mark. Right now I am at 1800 miles and really thinking about doing the change to mobil 1 this week but I am still debating it. If I do then I will post up if it helped or not.
