2025 Mazda CX-5 2.5L SkyActiv-G I4 Oil Specifications

Documented applicability

US market · Model years 2025 · Engine code SkyActiv-G 2.5 · Gasoline

  • Mazda's owner's manual requires 'Mazda Genuine 0W-20 Oil' for optimum fuel economy but does not publish a separate numeric Mazda material spec (unlike some other automakers' proprietary oil standards).
  • The OEM oil filter part number and drain-plug torque were not found in Mazda's public owner's manual or specifications pages and are intentionally omitted rather than sourced from a parts-catalog search snippet or forum figure.
  • Mazda's scheduled-maintenance document is served under the 2025 CX-5 manual path but carries an internal edition label suggesting it may carry over from a prior model-year printing; the viscosity/capacity figures are independently confirmed on separate 2025-specific manual pages, so this is noted for transparency rather than treated as a contradiction.
  • engine_code uses Mazda's own SkyActiv-G branding as used throughout its manual and marketing materials, not a factory alphanumeric block code (commonly cited elsewhere as PY-VPS) — that code was not independently confirmed from a Mazda-operated source during this research pass, so it is not used here.

Complete Oil Specifications

Your 2025 Mazda CX-5 equipped with the 2.5L SkyActiv-G engine requires SAE 0W-20 oil that is API-certified for gasoline engines and conforms to current ILSAC standards, per Mazda’s owner’s manual.

Capacity

The 2.5L SkyActiv-G holds 4.5 liters (4.8 US quarts) of oil with a new filter, per Mazda’s specifications table.

Service Intervals

Mazda uses an electronic oil-life monitor that triggers a wrench indicator, but also publishes hard mileage caps:

  • Normal driving: every 12 months or 12,000 km (7,500 miles), whichever comes first.
  • Severe conditions (Schedule 2 — frequent short trips, extreme temperatures, dusty/off-road driving, towing): every 8,000 km (5,000 miles) or 6 months.

What We Couldn’t Confirm Yet

Mazda’s public owner’s manual and specifications pages don’t list a specific OEM oil filter part number or a drain-plug torque spec — we found neither in the manual itself, only in a blocked parts-catalog search snippet and unverified forum figures for the latter, so both are left off this page rather than published as OEM-confirmed.
