Mazda CX-90 Timing Chain Malaysia — 3.3T
CX-90 3.3T inline-6: timing chain (no belt). First inline-6 Mazda passenger car in decades — chain is new design, no failure pattern data yet from Malaysia. Regular 0W-20 oil changes at 10,000 km are the primary maintenance action to protect the chain. Turbocharged operation and PHEV start-stop: oil pressure build-up on startup is more critical — ensure oil is fresh and correct spec.
