At least the North American owners manual for a 2019 CX-5 says 8000 km or 6 months is the severe service interval. For what it's worth, the US/Canada recommendation is first for Mazda or Castrol (some sort of licensing agreement) 0W-20 and then for any current API SM, SN, or ILSAC rated 0W-20. Probably has to do with fuel economy requirements. For Mexico (where I don't believe the engine is any different) they still have the same recommendations, but 5W-30.
I understand that you're doing this for peace of mind given your hot climate, short trips, and just to make you feel like you're treating your vehicle right. Really though - if you're going to change it that often, I really don't see the point of going with anything that's more than a basic level of protection. Also - anything with the API SN Plus certification is going to meet a pretty high standard, even if it's marketed as "conventional".
More expensive oils don't really perform better for normally driven vehicles with short replacements. They might help if you're pushing the replacement interval or if it's a turbo.
is there a chance of cat poisoning if i change to often considering the oil is in the 700-800 max zppp levels?my cts had 3 cats gone when i changed every 2-2.5k kilometers,then again had bad coils to.
I don't think changing the oil too often is going to hurt. Wouldn't that be more a result of too much blow by? You wouldn't be creating more ZDDP, just replacing what's already there.
