The Mitsubishi Eclipse Cross 2.0L and 1.6L models both use 5W30 (5L) fully synthetic engine oil, with a replacement interval of 5,000 kilometers. Composition of engine oil: Engine oil consists of two parts: base oil and additives. The base oil is the main component of lubricating oil, determining its basic properties, while additives are an important part of lubricating oil. Types of engine oil: The SAE viscosity classification for winter oils includes grades such as 0W, 5W, 10W, and 15W. The symbol W stands for winter, and the smaller the number before W, the lower the low-temperature viscosity and the lower the applicable minimum temperature. The SAE viscosity classification for summer oils includes grades such as 20, 30, 40, and 50, where a larger number indicates higher viscosity and higher applicable maximum temperature.

I've been driving the Eclipse Cross for several years, always using 0W-20 full synthetic oil, which is explicitly recommended in the manual. Cold starts are exceptionally smooth - even during northern winters with temperatures below -10°C, morning startups are completely stress-free. During maintenance, I always supervise the mechanic to confirm the oil grade on the packaging. Once when the dealership suggested switching to 5W-30, I immediately checked the manual and refused - the engine is designed for low-viscosity oil, and changing arbitrarily might increase fuel consumption. After driving over 40,000 km, the engine still runs quietly. I change the oil every 7,000-8,000 km, with average fuel consumption around 8L/100km. I recommend all owners develop the habit of consulting the manual - keeping a copy in the trunk is the most reliable approach.

Last time when I went for maintenance on my Eclipse Cross, I specifically asked the technician and confirmed that the factory requires 0W-20 full synthetic engine oil. This viscosity grade has better fluidity and provides more thorough protection for the engine internals. The technician mentioned that if you're in southern regions with extremely hot summers, you might consider 5W-30, but for my car in Jiangsu, 0W-20 works perfectly fine. Remember to replace the oil filter simultaneously during oil changes - I once saw a customer at the next service bay skip replacing the filter to save money, which resulted in the new oil being contaminated by the old filter. The Mitsubishi genuine oil set costs around 400+ RMB, while purchasing international brand oil of the same specification yourself could save about 100 RMB, but make sure to identify the anti-counterfeit labels.

As a female car owner, I'm most afraid of being fooled by auto repair shops. I always strictly follow the maintenance manual to choose 0W-20 oil for my Eclipse Cross. I remember the first time I went to a roadside shop, the boss insisted that 5W-40 would be better, but I refuted him on the spot with the manual in hand. Low-viscosity oil not only saves fuel but also causes less engine wear during cold starts. Now I take a photo of the odometer before each maintenance, and after changing the oil, I can clearly feel the throttle response becomes more agile. However, I must remind everyone that different model years may have different requirements - my 2019 model and my friend's 2021 model have different oil capacities.

After a self-driving trip to Tibet, I truly understood the importance of engine oil. My Eclipse Cross relied entirely on 0W-20 oil in the high-altitude low-temperature environment, starting effortlessly even at -20°C. This full-synthetic oil has strong shear resistance, maintaining stable power even after 10 hours of continuous driving on winding mountain roads. Compared to my previous experience using the wrong 5W-30 oil, fuel consumption increased by 0.8 liters. I recommend car owners choose oil with GF-6 certification for better cleaning performance. Now, every time I change the oil, I ask the mechanic to check the dipstick level to ensure it's ideally in the middle of the scale.
