Service Bulletin #00-002 /16 Its what I've been saying for years

NOTE: The following services are not included in Mazda’s Factory Scheduled Maintenance:
Service Notes
Transmission flushes
• Transmission fluid flushing should only be performed when instructed
by Workshop Manual or any other Mazda publication.
• Transmission fluid replacement is only recommended on B-Series
Truck and Tribute and should be performed only at the mileage intervals
specified in the owner’s manual.
• Transmission flushing is recommended if the customer accidentally adjusted
the transmission level using an incompatible type of fluid.
Transmission oil additives
• Transmission oil additives could (under certain conditions) lead to
internal damage and void the warranty.
Engine flushes
• Engine oil flushes are unnecessary.
• Contaminated oil from flushing machines may damage the engine and
void the warranty.
Engine oil additives
• These additives could (under certain conditions) lead to engine
damage, prevent piston rings from sealing, and void the warranty.
Engine cooling system
flushing
• Mazda recommends coolant replacement starting at 100,000 miles of
service on some vehicles and 2 years on others, depending on the
model.
• Flushing the coolant system is only recommended if the customer accidentally
adjusted the coolant level using an incompatible type of coolant.
• Flushing machines that “recondition” the existing coolant should never
be used. This procedure cannot completely reverse the chemical deterioration
that occurs to the coolant during use.
Cleaning of injectors
• Cleaning injectors without an actual power related complaint from the
customer, does not improve engine performance.
• Fuel injector malfunctions should only be repaired by replacement.
Nitrogen for tires
• Compressed air contains approximately 80 percent nitrogen.
• There is no practical value added from filling tires with nitrogen.
Brake fluid flushes
• Brake fluid flushing should only be performed when instructed by
Workshop Manual or any other Mazda publication.
• Contaminated fluid from flushing machines may damage the brake
system and void the warranty.
Power Steering fluid flushes
• Power Steering fluid flushing should only be performed when instructed
by Workshop Manual or any other Mazda publication.
• Contaminated fluid from flushing machines may damage the power
steering system and void the warranty.

Never have had any the above on my cars, 30 year old 86 vw golf (gas) or 14 year old ford ranger still running strong. Save your money!:laugh2:

Been saying same as above for years now. Great to see mazda has had enough of the stupidity.

People have this strange urge to dump in various cleaners, chemicals and do unnecessary maintenance. Shops prey on this.

You'll always hear people justify this with 'my car still runs great years later!' true, but it would run just as well without that garbage too.
