What Oil Does a 2025 Mazda CX-90 Take?

Choosing the right motor oil for your 2025 Mazda CX-90 is essential for optimal engine health. Mazda’s engineers have designed the 2.5L 4-cylinder (Engine Code [A] A) to run best on a specific oil type and viscosity:

• 0W-20 Full Synthetic (All Temperatures): This is Mazda’s recommended oil for the CX-90. It provides excellent protection for cold starts while maintaining viscosity at high temperatures. Using 0W-20 ensures smoother engine operation, better fuel economy, and reduced engine wear.

Why 0W-20? Modern Mazda engines have tight tolerances and advanced variable valve timing, making thin, stable oil critical under all climate conditions. Always stick to the manufacturer’s recommendation to keep your warranty and maximize performance.

2025 Mazda CX-90 Oil Capacity

The engine oil capacity for the 2025 Mazda CX-90 2.5L engine is 4.8 quarts (4.5 liters) when performing an oil and filter change.

• Always double-check the oil level with your dipstick after refill to ensure it’s in the safe range.
• Pro Tip: Overfilling your engine can cause foaming, increased oil pressure, or damage internal seals. If you add too much, drain the excess to protect your engine.

How Often Should You Change the Oil on a 2025 Mazda CX-90?

The recommended oil change interval for the 2025 Mazda CX-90 using full synthetic oil like 0W-20 is every 7,500 miles or 12 months—whichever comes first. If you drive in severe conditions (frequent short trips, towing, extreme temperatures), change the oil sooner—typically every 5,000 miles.

Conventional oil should be changed more frequently, but Mazda strongly advises full synthetic for best protection. Even with synthetic, watch for these reasons to change oil early:

• Engine oil looks dark or sludgy
• Oil change indicator or engine light appears
• Noticeable drop in engine performance or fuel economy

Oil Filter for the 2025 Mazda CX-90

The oil filter’s job is to trap particles and protect your engine from sludge and wear. For the 2025 CX-90, Costa Oil uses filter part number COF4622—engineered to OEM-specs for superior filtration. Using the right oil filter helps ensure proper oil flow and maximum protection. Avoid generic filters that may not meet Mazda’s exact standards and always replace with quality filters for your vehicle.
