Mazda CX-90 Oil Type | All Model Years

Choosing the correct oil keeps the Mazda CX-90’s turbocharged inline-six and plug-in hybrid powertrains running at peak efficiency, protects timing chains and turbo bearings, and supports cold-start performance. Below is a clear, model-year–grouped reference you can trust. As a Mazda retailer, Sport Mazda South follows factory literature, uses Genuine Mazda Premium Oil, and sets vehicles to the maintenance monitor’s interval after every service.

2024–2025 CX-90 (3.3L e-SKYACTIV-G Turbo): Oil type

For U.S. and Canada models equipped with the 3.3-liter inline-six (standard or Turbo S), Mazda specifies SAE 0W-20 engine oil. The owner’s manual calls for oil carrying the API “Certified for Gasoline Engines” mark and ILSAC certification for fuel-economy and emissions protection.

Helpful shop note: With an oil filter change, the 3.3L uses approximately 6.3 U.S. quarts (6.0 L). Always confirm level via the vehicle’s on-screen oil measurement procedure after the engine reaches operating temperature.

Why Mazda specifies 0W-20 here: this viscosity ensures quick circulation at start-up while meeting Mazda’s calibration targets for the inline-six’s mild-hybrid system and turbocharger. Sticking with API SP / ILSAC GF-6 oils helps manage modern GDI concerns (deposit control, LSPI mitigation, and timing-chain wear). The recommendation is the same for 2024 and 2025, so owners can confidently use the same oil grade across these years.

2024–2025 CX-90 Plug-In Hybrid (e-SKYACTIV PHEV): Oil type

The CX-90 PHEV also specifies SAE 0W-20 in North America. Mazda’s PHEV owner’s manual lists 0W-20 and the same API/ILSAC requirements noted above. Because PHEVs often operate in short engine-on cycles, consistent use of the correct low-viscosity synthetic oil supports rapid lubrication when the engine engages from EV driving.

Capacity reminder: the PHEV’s 2.5-liter engine uses less oil than the inline-six—about 4.8 U.S. quarts (4.5 L) with filter. Verify level via the center display’s oil-level check, as described in the manual.

Outside the U.S. & Canada: Different spec

Mazda documents a regional exception: markets outside the U.S./Canada may list SAE 5W-30 as the recommended grade (Mexico shown explicitly), while still permitting 0W-20 in North America. If you’re importing a vehicle or reading non-U.S. documentation, follow the label under the hood and the manual for your market.

Practical tips from our service lane

• Use a high-quality full synthetic that meets API SP and ILSAC GF-6; Genuine Mazda Premium Oil 0W-20 is formulated for Mazda engines and is what we use at the dealership.
• Replace the crush washer and torque the drain plug per service information; then confirm level using the CX-90’s on-screen measurement routine (rather than a dipstick) after a complete warm-up.
• Reset the maintenance monitor and check for software updates while you’re in—Mazda calibrations are designed around the specified oil viscosity.

What we recommend at Sport Mazda South

For every 2024–2025 CX-90—whether the 3.3L Turbo or the Plug-In Hybrid—use SAE 0W-20, API SP/ILSAC-certified oil. Expect about 6.3 quarts with filter on the inline-six and 4.8 quarts with filter on the PHEV, then verify electronically to final level. These are the same requirements across the two model years noted above, which simplifies maintenance planning for multi-CX-90 households and fleet customers.

Conclusion

The CX-90’s factory guidance is straightforward: in the U.S. and Canada, use SAE 0W-20 full synthetic that meets current API/ILSAC standards—across both turbo inline-six and PHEV variants—for 2024 and 2025 model years. That single grade supports cold-start protection, turbo reliability, and the vehicle’s fuel-economy targets. If you’d like, our Mazda-trained technicians can handle the service with Genuine Mazda Premium Oil and return your CX-90 with the maintenance monitor properly set and a multi-point inspection completed.
