My girlfriend and I just purchased a brand new 2007 Tiburon GT. This car has the 2.7L DOHC V6 and from what I can tell they recommend a 20 weight. The car currently has 500 miles on it and I am planning on changing it at 3000. Does anyone have any expereience on what type and brands of oil this car seems to like. I am definatly planning on running a synthetic of some type, just not sure what kind.
