Sorry i made a mistake. My Manual says 5W20
The early manuals say 5W20. The later manuals and the shop manual say 5W20 for the NA motor, 5W30 for the turbo.

Does anyone here work for mazda that can say for sure. OR better an engineer that can say some big words and convince me either way which oil to buy?

Antidisestablishmentarianism.
