2005 XG350 oil question

I live in Peoria AZ. In the summer I have seen it hit 110-115 regularly.
I am planning to do my oil changes. I note in the XG350 2005 owner's manual
it recommends 5W-20 or 5W-30.
With our summer temperature extremes I wonder if 20W-50 would be more
appropriate.
Also where is the oil filter located and is it spin on or cartridge?
Thank you,
Seamus J. Wilson

 

My guess is that the engineers that developed the engine have at least read
about summers in Arizona, if not actually have been there at some time. If
20W-50 was appropriate, they may have put a footnote for Arizona drivers.

location.

 

Thank you Ed for the kind help.

I live in Northern AZ (similar climate to PHX) and my Hyundai dealer
recommends and uses Castrol GTX 10W30 in 2006 Sonata LX

Just my dos centavos...


P.S.- 110, in the evening, right?

If your owner's manual recommends 5W-20 or 5W-30 in your climate, 20W-50 is
far too viscous.
