The CX-5’s 2017 model year uses SAE 0W-20 full synthetic motor oil in its SKYACTIV-G engines.
Beyond the short answer, this article explains the oil grade, capacity, and maintenance intervals for the 2017 CX-5 and notes regional variations you might encounter depending on engine and market.
Recommended oil specifications
Key details to ensure correct oil selection include viscosity, oil type, and certification references.
- Viscosity: SAE 0W-20
- Oil type: Full synthetic (or high-quality synthetic blend as allowed by Mazda in certain markets)
- API service rating: SN or higher
- ILSAC rating: GF-5 or GF-6 (compatible with Mazda engines)
- Engine compatibility: Suitable for SKYACTIV-G engines in the CX-5 2017
In short, use a 0W-20 synthetic oil that meets API SN or higher and ILSAC GF-5/6 specifications to maintain warranty and performance. Always verify the exact specification for your region and engine variant in the owner’s manual.
Oil capacity and change intervals
Knowing how much oil your CX-5 holds and how often to change it helps plan maintenance and keeps the engine within factory tolerances.
- Oil capacity with filter change (2.5L SKYACTIV-G): approximately 4.7 quarts (4.4 liters)
- Recommended oil change interval (normal driving with synthetic oil): about every 7,500 miles (12,000 kilometers); reduce to 5,000-7,500 miles (8,000-12,000 km) under severe driving conditions
- Maintenance Minder: Mazda’s interval reminders can adjust schedules based on driving style and conditions
As always, consult the owner's manual or your dealer for the precise capacity for your exact engine and regional specs, and follow the Maintenance Minder guidance for oil life. Regular checks of oil level and quality are recommended between changes.
Additional notes and regional variations
While 0W-20 synthetic is standard for most 2017 CX-5 models, some markets with different engine options or climates may call for alternative grades. For example, certain diesel or European-market variants might have different recommendations. Always adhere to the local Mazda service information for your vehicle.
Why the 0W-20 grade matters
0W-20 oil offers lower viscosity at startup in cold climates, improving fuel economy and reducing engine wear during cold starts—benefits Mazda highlights for its SKYACTIV engineering.
Summary
The 2017 Mazda CX-5 generally requires SAE 0W-20 full synthetic oil (API SN or higher, ILSAC GF-5/6) and uses roughly 4.7 quarts with a filter. Change intervals are about every 7,500 miles under normal conditions, with adjustments for severe driving. Always consult the owner's manual and regional Mazda guidance for your specific engine variant and climate.
