What is a good oil grade in the engine listed above for 110*F+ temps the owners manual has every grade possible listed i was thinkin 10w40 or 15w40 no syn please i like the dino in this car. i do mostly highway driving with stop and go alot. but what are the opinions of you all.

Hyundai lists 20W-40 and 20W-50 as useable grades as well so your choice of a 15w40 looks fine. I am a Synthetic guy but if I were to use a dino oil I would look at Castrol GTX first. Have you concidered a Synth Blend in place of a full? With the heat you get out there in AZ the stronger Synthetice would serve you well.
