Flipped through the maintenance manual again to see if the schedule called for any such service and it's ignored. Every other thing you can think of is supposed to be checked regularly (some things that usually are of no consequence). Yet, this critical thing to engine longevity gets no mention. Many people will not know that GDI engines need this preventive measure and will be caught off guard when it gets to a breaking point and become an expensive issue.
I bet this isn't just missing from Mazda's schedules, but likely all other brands. As if OEM's don't want to admit carbon buildup is a reality of direct injection.
Anyway, there's preventive products you can use and dealer service you can get to prevent a deep dive cleaning down the road (full engine tear down).
What do you guys think about this?
