Mazda CX9 Owners and Likers Thread

[ano727]

What is your fuel choice for the CX9? They found carbon deposits in my car which was causing the engine noise. It looks like premium fuels like XCS is not compatible to CX9's engine.

Used to always load up with XCS. Pero Mazda C5 SA (mukhang he knows a lot about CX9) suggested to use 91RON only, preferably Shell or Caltex. He said CX9 engine is optimised for 91RON fuel. Though I can feel more response and power with XCS(95RON). There were several cases daw of engine noise with CX5, and common pattern is they use Petron XCS.

Been using Shell 91RON ever since.

Suggest you try muna strict 91RON either Caltex or Shell and observe.
