Mazda Maintenance advice for extremely hot dusty environments?

Hello, we are a group of mazda 3,6,cx 3,5,30 owners live in extreme hot , dusty environment with an average temperature 109 °F and the owner's manual doesn't have any hot countries and we have a few questions after I have read a lot of discussions.

1 - We compared ATFs and found that mz-fz is fully synthatic made by idemitsu indonesia , toyota ws is meniral oil have group 3,4,5 , louqi moly 1800 are semilar to mazda fz but half priced and semi synthetic , dexron vi and KIXX ATF DX-VI are a bit thicker , quarter of the price and fully synthetic can we mix mz-fz with dexron vi , and when to drain and fil ? all data sheets are here Google Translate.

2 - Are catch cans necessary if we use 0w20, 5w30 api sp , sn + , low sulfer , because on our experience with 43500miles , 25 miles car there is minimal carbon build up on cylinder valve maybe of the heat?

3 - Regarding bulit in mazda oil/air seperator under pcv when to clean them and how , what did mazda change after this article because my car is 2.0 2015 Mazda CX-9.

4 - When to change transmision cooler because there is a website recommend to change it every 4-5 years Google Translate 4- when to change break fluid in in dry environment because I haven't found an accurate tester.

5 - Will cleaning maf, oxygen synsor with maf cleaner damage it , what is the recommended interval?

6 - Fl22 and motorcraft vc10a2 are semilar , and motorcrafet said " Motorcraft® Yellow Antifreeze/Coolant can be used to top-off or entirely replace (drain and refill) antifreeze/coolant in vehicles factory-filled with Motorcraft® Specialty Green Engine Coolant. https://www.fcsdchemicalsandlubricants.com/quickref/FCSD Motorcraft Yellow Antifreeze-Coolant Backward Compatability.pdf , but in the newer SDS the yellow has <3% 2-eha https://www.msds.ford.com/documents/201944 D_GBEN.pdf
is it better than fl22?,, can we dilute it with 35/65 distilled watter to increase heat exchange (in 0.951 quart Measuring Cup , 0.62 quarts premix , 0.33 quarts distilled water.

7 - What do think of this schedule:
each 5.6k miles or 6 months
: engine oil and filter , clean engine air filter by hitting it only , clean engine air box with air gun while closing maf inlet , injector cleaner , clean radiator from the back to front with air gun ,
each 11.2k miles : cabin filter , tyer rotation
each 18.6k miles : replace engine air filter
each 37.3 or 43.5 : drain and fill transmission fluid with filter , fuel filter PE11-13-ZE0 and PE01-13-ZE1(fuel here is grade EURO 5 , SULFER-FREE
each 62k miles : coolant flush , both engine belt and tensioner , pour catalytic converter cleaner in oxygen sensor inlet , spark plugs , clean maf , manual cleaning with brush valve, intake , intake manifold with there specific cleaner ,, throttle body , break fluid synthetic dot3 because it has longer life than dot4
each 124 miles water pump and thermostat and radiator cap

Thanks and we really appreciate your help.

1 - I would use OEM Mazda fluid only. Interval should be stated in your Owner's Manual.

2 - Catch cans are not necessary IMO. Will they help? Maybe. But if you have checked, and there is minimal carbon build-up, I wouldn't bother.

3 - To my knowledge there is no specified service interval for the PCV or the transmission cooler. Inspect for signs of failure and replace whenever necessary.

4 - Brake fluid change can be done every 2-3 years, but if you have a reliable tester I would just check the fluid annually and change it if it falls out of spec.

5 - Again, no service interval for MAF sensor, so I would service/clean with MAF sensor cleaner at your own leisure or whenever you start to experience problems.

6 - I would just stick with any FL-22 coolant if available, I would not experiment with different mixes, personally.

7 - I would follow the maintenance schedule for EU (assuming you are in the EU). There is nothing wrong with slightly shorter maintenance intervals to accommodate your environment. Personally I would skip injector cleaner if you have "top tier" gasoline available, and I would just use whatever brake fluid the car uses from the factory.


For your service interval and fluid questions, I would try to contact Mazda Corporate directly to see if they can advise. Good luck!

Isn't the chemical composition of DOT 3 different than DOT 4?

I thought they were not compatible.
