I am curious if people in hot climates use 0w-20 weight oil. It is going to get warmer fast where I am, and 0w-20 is such a low viscosity. Mazda recommends it so I am using it.
Do people living in hot climates such as Texas or Arizona use 0w-20?

I did in my 2015 CX5. I lived in NWA at the time, and drove through TX a lot. 106K miles when traded, and zero engine issues.

5qt. jug of 0w20 Castrol Edge from Walmart for me. Has been anywhere from $19 - $28.

Pretty good deal.
I actually noticed running the longer oil change interval, that I needed to add a quart around 5k miles. I am at 6k now. I noticed last oil change I did that I was down a quart, and now I confirmed it again. Not sure what that means. :\

Castrol Edge at my Walmart is $30 bucks. It went up in price.

Price seems to fluctuate a lot here. I have never paid the same price for it.
Once was $19, next was $28, then again was $24.

I use 0w20 mazda moly. This would be my first Arizona summer on the cx5.
Have to change 5k miles or 6mo because of the warranty.
Once I do my next uoa I can share and compare with my first uoa in winter weather...if phx can have winter
Last cars were run here with 5w20 blend and no issues . Key here is to change it regularly.
re,Castrol, I noticed the same. My local walmart price goes up and down when they have promos every month.Now is 29 used to be 24 last month.
Its tempting but I get mazda moly for around 35$ and that satisfies me.

Mazda recommends flexible oil change interval for 2018 CX-5 which is up to 7,500 miles or 12 months. This should satisfy the warranty requirement.
I use 0W-20 Mazda moly in Texas. I'm tempting to use 5W-30 oil where Mazda recommends it for SkyActiv-G to other regions in the world.
I highly advise considering:
-Transmission fluid drain/fills. Our desert high heat environment is extreme.
-Consider 7k mile oil changes but check level at 5k miles. I have good results with Pennzoil Platinum 0w20 not burning off.
-Change oil in February to last through July. Then July through January. To mitigate oil to full exposure to our 4-month 100-degree summers.
-Using AEM Dry flow filters. Folks don't realize how just one sand storm accumulates as much sand in our engine filter as 1 year in other cars. Reusable filter.
-I'm currently experimenting with Amsoil 0w20 Signature Series oil. My cousin in Gilbert, AZ is using it in his Mazda3 and sent oil analysis to Blackstone labs at 1-year/10k miles. Got good results back.

Just checked the owner's manual for 2018 CX-5. Schedule 2 (severe driving conditions) still uses Flexible maintenance for oil change, although there're 2 exceptions:
- Extended periods of idling or low-speed operation such as police car, taxi or driving school car.
- Driving in dusty conditions.
