Why 0W-20 is Critical for This Engine
Mazda’s Skyactiv-G technology utilizes high compression and sophisticated variable valve timing (VVT). The 0W-20 viscosity is precisely engineered to provide immediate lubrication to these tight-tolerance components, reducing internal friction and maximizing both fuel efficiency and engine responsiveness.
Using incorrect oil will:
- ❌ Decrease fuel economy and increase CO2 emissions
- ❌ Cause sluggish response from the Skyactiv-G VVT system
- ❌ Potential increase in engine noise during cold cold-starts
Mazda-Approved Oil Brands

✅ Castrol Edge 0W-20
-
✅ Mobil 1 Advanced Fuel Economy 0W-20
-
✅ Valvoline Advanced Full Synthetic 0W-20
-
