not a MAZDA forum for help?

to listen to different opinion

can monitor

on our cars engine and transmission temp range between 195.8 - 215.6 F

Don't you all think?

agree

run 0w40 winter

unfortunately the owner manual oil chart doesnt include 0w40 , actually iam planing to use https://www.shell.com.sg/motorists/...-fully-synthetic/shell-helix-ultra-0w-20.html i read that its better for gentle drivers and has better protection and lower carbon deposit than fully synthetic api sp 5w30

owners manual.

the issue is there is no schedule for any dusty dry hot climate

Well, what years are these vehicles? The later skyactiv engines had a redesign that keeps the intake valves hotter to help burn off the carbon. I wouldn't mix transmission fluids, I would just use what Mazda says to use. These transmissions aren't cheap to replace so I wouldn't risk putting anything in other than their recommended fluid.

Where did you get this info ..?

Well switching to synthetic would not hurt. And review owners manual. Is 109F considered severe service, if so follow the severe service section for vehicle maintenance.

I assume batteries will not last more than 2-3 years.
