Oil weight Question...
Getting ready for my first oil change. I live in Phoenix and the summer temperatures easily top 110 daily. My question is can you use 10-30 Mobil 1 versus 5-30 Mobil 1. Not being an oil wizard it seems the 10-30 might be better at those daily temperatures, especially stuck in traffic. Any input is appreciated.

Not sure if it's in your owner's manual at the back, but there could be alternative viscosities that you can use, under certain conditions. If not, use what the mfr. says to use, per above post.

Modern synthetics like Mobil 1 no longer have that problem so there is no reason to not use 5W-30 in your climate.
M1 10W-30 would do no harm in your climate, but 10W-30 no longer offers any advantages over 5W-30.
