There is a chart in your owners manual with recommended viscosities vs. ambient temperatures. If you look at that chart you'll see that both 5W30 and 10W30 are acceptable for most temp ranges. Since you're in CA you should be fine with 10W30 year-round.

thats what I've used now 3 times in a row. MPG has gone up by 1 or 2 but that might be power of persuasion (well, I mean it actually has gone up, but it might have nothing to do with the oil) before that I was using that Q stuff most of the time.
I also put that mobil 1 clean 7500 in my moms car because she drives an insane amount and usually goes about that distance before telling me she needs her oil changed
