in 110+ degree weather, should I use a heavier oil than the usual Mobil 1 10W-30?
My RX will spend the next month and half in 110+ degree
weather.(visiting family in suburb of Arizona)
Since day 1, my RX has had nothing but Mobil 1 10W-30
in the engine.(Mid-Atlantic area)
When I'm down in Arizona in such hot temps, should I use
a heavier oil? For example, Mobil 1 0w-40?(which is what
I use in my MB)
Thansk for any advice!

Cant go wrong with 10w40, but the real authority is your owner's manual.

One thing to consider if you want to change oil weight .... try to keep the same brand and type.
I dont mean to say that once you use one brand and type you are stuck for ever. Just switching them frequently after being on one for a long time, introduces different detergents and additives which can interact and also can shock an established system.
To repeat ... I doubt if any thing real bad will happen but consistency is better, specially if you have been happy with a particular brand and type.
Finally, there is no scientific data behind my claim.
The weight of oil to use is based on use and ambient temperature. Before multigrade oil like 0-40 the oil had to be changed based on seasons. 30 wieght should cover up to 110 [but the authority is the published value in the user manual]
