What is the proper engine oil weight range for the 7m-gte?

I live in Denver, similar temp variations. I usually run 10W-30 up until early summer and then switch to 10W-40. Depends on how hard you're going to be running the car and how well your cooling system is doing it's job.

I used to run Castrol GTX High Mileage, but now that most of the engine's rebuilt and all of my seals are new I run a synthetic blend.
