I would be a little leary of a 20-50 oil. The oil pump may not pick up a thicker oil when first starting the engine. Initial start up is the most critical time for any engine. Rotella 15-40 will likely work well and is designed to live in really hard working work engines in big trucks.
Keep in mind the GZ is used in many other countries where temps reach much higher than Texas and somehow survive.
Or just change oil a bit more often to prevent oil break down from heat. Always keep the oil topped up as it is used to carry away heat internally.
