I just bought a 2009 Camry Hybrid 2 weeks ago. The maintenance required soon light is on indicating that it's almost time for an oil change. The manual says 0W-20 or 5W-20. I'm looking at using Mobil1 advance fuel economy 0W-20. However I live in Oklahoma and Summer here gets over 100 degrees. Sometimes over 110. Is it OK to use 0W-20 in the Summer if it gets extremely hot?

 

Yes. I use Mobil 1 0W-20 in Phoenix in all my Toyota hybrids.
