Mazda CX4 uses 0W20 engine oil. In the oil grade 0W20, 'W' stands for 'winter', the number before 'W' represents the freezing point temperature, and the number after 'W' indicates the kinematic viscosity of the oil at 100 degrees Celsius. A higher number means higher viscosity. The Mazda CX4 is a compact SUV under the Mazda brand, with dimensions of 4637mm in length, 1855mm in width, and 1524mm in height, and a wheelbase of 2700mm. In terms of exterior design, the front face of the Mazda CX4 continues Mazda's KODO design philosophy, featuring a shield-shaped grille with chrome trim below that adds a touch of sharpness to the front.

I bought a Mazda CX-4 last year. When getting it serviced at the dealership, the mechanic said I must use 0W-20 full synthetic oil. I tried it myself, and this oil grade makes the engine run smoother, accelerates faster, and saves a few cents on fuel. The manual also recommends using 0W-20, meeting API SP or GF-6 standards. When driving uphill on highways, the engine temperature remains stable. If you randomly choose other grades like 10W-30, it may increase wear and cause louder noise. In summer or cold regions, thinner oil helps with quick cold starts and avoids wear. Don’t switch oils to save money—it’s not worth shortening your car’s lifespan. Change it regularly every 8,000 km to maintain lubrication. I recommend the original formula oil and getting it done at an authorized service center.

In actual car repair practice, the Mazda CX-4 engine is designed for 0W-20 oil, preferably the full synthetic version. This viscosity ensures fluid flow and reduces frictional heat loss. API certification guarantees oxidation resistance and wear protection. Avoid trying higher viscosities like 5W-40, as it can hinder power response, cause sluggish acceleration, and increase fuel consumption. The manual emphasizes the necessity to match the standard, otherwise engine issues may arise, leading to higher repair costs. For routine maintenance, choose compatible brands like Mobil 1. Neglecting the oil change interval can lead to accumulated contaminants and clogging. Use thinner oil in winter to prevent cold start difficulties. Overall, sticking to the recommended type is the safest and most reliable approach.

The Mazda CX-4's Skyactiv engine is really cool and requires 0W-20 oil for optimal performance. Low-viscosity oil flows quickly at startup, protecting parts with minimal wear. API standards like SP grade provide cleanliness and prevent carbon buildup. Mismatched grades like 15W-50 increase resistance, causing loud noise and affecting acceleration smoothness. For oil upgrades, choose premium brands while maintaining the same viscosity. Long-term neglect of oil changes leads to high risks of oil degradation. Simply following the manufacturer's guidelines ensures safety and peace of mind.
