What type of engine oil is used in the Mazda CX-4?

Mazda CX-4's Skyactiv-G engine uses the original 0W20 engine oil. Below is an introduction to the engine oil for the Mazda CX-4: 1. 0W20 refers to the SAE standard viscosity value, indicating that this oil is a multi-grade oil. 2. W stands for WINTER, and the number before W represents the oil's flow performance at low temperatures. The smaller the number, the better the starting performance at low temperatures. The number after W represents the oil's stability at high temperatures. The larger the number, the better the oil's high-temperature stability. 3. The smaller the number before W, the lower the oil's low-temperature viscosity, the better its low-temperature fluidity, and the lower the minimum applicable temperature.
When choosing engine oil for Mazda CX-4, focus on three key points: The Skyactiv engine requires 0W-20 or 5W-30 oil, as clearly stated in the manual. My own 2.5L model has always used the factory-recommended 0W-20 full synthetic, making cold starts noticeably smoother. If the car has over 50,000 km, mechanics suggest trying 30-viscosity oil, but never randomly switch to 40-grade. Always look for GF-6/SP certification – counterfeit products are rampant these days. Last time I cheaped out on an unknown brand and fuel consumption increased by over 1L. Also check for the 'SN PLUS' mark on the packaging, otherwise it may clog the particulate filter. Always supervise oil changes – I once caught a mechanic mixing leftover oil.
Having worked in auto repair for ten years, I've handled dozens of CX-4s. The manufacturer requires 0W-20 full synthetic oil, especially for engines with the SKYACTIV badge. Northern friends, take note: in winter temperatures of -25°C, 5W-30 oil doesn't flow well enough. Keep oil change intervals between 7,000 to 10,000 km; reduce to 6,000 km if frequently stuck in traffic. A detail to remember: newer models with GPF particulate filters require low-ash oil meeting ACEA C5 standards, or the check engine light will come on within six months. Last week, a ride-hailing CX-4 ruined its catalytic converter by using high-ash oil. During maintenance, ask the mechanic to check the oil dipstick O-ring - it can leak when aged.
Remember four key letters: 0W-20. In southern cities, 5W-30 can be used as an alternative, but avoid oils starting with 10W. It's recommended to choose big-brand full synthetics, such as Mobil EP or Idemitsu ZEPRO, and never settle for semi-synthetic. The maintenance manual clearly states the suitability of ACEA A5/B5 standards, which is more accurate than simply looking at API grades. If you often drive in mountainous areas, changing the oil 2,000 kilometers earlier provides extra peace of mind. When bringing your own oil, make sure it's a 4-liter container. Adding 4.2 liters to a 2.0L model will cause overflow. I learned this the hard way—adding that extra half-liter resulted in excessive crankcase pressure, leading to oil seal leakage and an 800-yuan repair bill.
