The 2014 Mazda6 typically requires SAE 0W-20 full‑synthetic engine oil, with about 4.5 quarts (roughly 4.3 liters) needed for a complete change including the filter.
In practice, Mazda’s owners manual specifies 0W-20 synthetic oil that meets ILSAC GF-5 (or newer) for the 2.5L SKYACTIV‑G engine used in most 2014 Mazda6 models. The exact grade and capacity can vary by market and engine variant, so always check your vehicle’s manual or the door jamb sticker to confirm the specification for your car.
