The owners manual has several different weights listed depending on the ambient temperature in which the car is to be driven. 5w30 is recommended up to 100 degrees. over that and it is recommending a 20w50. I would use a good synthetic 5w30 which is good for much higher temperatures and will easily perform well in the +100 degree range as well as the -0 temp range. Mobil 1 or Amsoil fit the bill nicely.
