Complete Oil Specifications
Your 2022 Mazda CX-30 with the naturally aspirated 2.5L engine requires 0W-20 full synthetic oil that meets API SP and ILSAC GF-6A certification standards.
Quick Reference
| Specification | Value |
|---|---|
| Viscosity | 0W-20 |
| API Rating | API SP |
| ILSAC Rating | GF-6A |
| Capacity (with filter) | 4.8 quarts |
| Oil Filter | Mazda 1WPE-14-302 |
| Normal Interval | 7500 miles |
*Note: If you have the 2.5L Turbocharged engine, your vehicle requires 5W-30 synthetic oil instead, due to the extreme heat generated by the turbo.
Why 0W-20 is Critical for This Engine
Mazda’s Skyactiv-G engines utilize an exceptionally high compression ratio (often 13.0:1) to squeeze maximum energy out of every drop of fuel. This high compression creates unique stresses, which is why 0W-20 oil with an API SP rating is required to protect against Low-Speed Pre-Ignition (LSPI) and to provide immediate lubrication upon cold starts using the complex 4-2-1 exhaust manifold.
Using incorrect oil will:
- ❌ Provide slower lubrication to the aluminum block components when cold
- ❌ Risk engine knocking (LSPI) under load
- ❌ Negatively impact your fuel efficiency
Mazda-Approved Oil Brands
-
✅ Genuine Mazda Original Oil 0W-20
-
✅ Castrol Edge Advanced Full Synthetic 0W-20
-
✅ Mobil 1 Advanced Fuel Economy 0W-20
-
✅ Pennzoil Platinum Full Synthetic 0W-20
-
✅ Valvoline Advanced Full Synthetic 0W-20
Mazda specifies that Castrol is their preferred oil brand worldwide, but any high-quality full synthetic bearing the ILSAC GF-6A starburst symbol is completely acceptable.
Severe Service Check
Mazda advises shortening the oil change interval to 5000 miles or 6 months under the following severe conditions:
- Idling for extended periods or driving at low speeds in heavy traffic
- Driving predominantly on short trips where the engine does not reach full operating temperature
- Driving in extremely dusty, muddy, or sandy areas
- Driving in exceptionally hot (above 90°F) or cold weather (below freezing)
Installation Details
Drain Plug Torque: 26 ft-lbs
Mazda drain plugs use an aluminum crush washer. Always employ a new crush washer to prevent frustrating slow leaks from your oil pan.
OEM Filter: Mazda 1WPE-14-302 (often supersedes PE01-14-302A)
Aftermarket Filters:
-
Mobil 1 M1-108A
-
WIX 51358
-
K&N PS-1008
Pro Tip: Your Mazda utilizes a plastic access cover (splash shield) underneath the engine. You will need a Phillips head screwdriver or a 10mm socket to remove the flap and access the spin-on filter and the large 8mm hex key drain plug.
FAQs
What oil does a 2022 Mazda CX-30 2.5L non-turbo take?
It requires 0W-20 full synthetic engine oil certified to API SP standards.
How many quarts does it need?
4.8 quarts (4.5 liters) when you are completely draining the oil and replacing the filter.
Can I use 5W-30 instead?
Only if you have the 2.5L Turbo model. The non-turbo model explicitly calls for 0W-20 for optimal performance and efficiency.
Is synthetic oil required?
Yes. 0W-20 viscosity is only achievable using a full synthetic base oil.
How often should I change the oil?
Mazda recommends changing the oil every 7500 miles or 12 months for normal driving. For those operating within the severe driving category (e.g., predominantly city driving), change it every 5000 miles or 6 months.
