Exactly if the manual says use 10w-60 put that in your car, if it says 10w-40 put that in. The 60 part is important for hot climates or high temperatures, the GTA is not a cool engine so could warrant this, although I personally believe for normal road use a 10w-40 would be fine, track use absolutely need the higher grade oil.
