Refine S3 can use 5W30 or 0W30 engine oil. The Jianghuai Refine S3 is a compact urban SUV produced by Jianghuai Automobile, primarily targeting young consumers. The Refine S3 is equipped with a 4GB1.5L engine, delivering a maximum torque of 146 Nm, paired with either a 6MT or CVT transmission system. For the interior, the Refine S3 features a dark color scheme with red stitching, a three-spoke multifunction steering wheel wrapped in leather, integrated audio controls, cruise control, and Bluetooth functionality. Externally, it adopts Jianghuai's signature "Bottle Mouth" design, complemented by chrome-enhanced front grille and triangular-shaped fog lights. In terms of dimensions, the vehicle measures 4325mm in length, 1765mm in width, and 1625mm in height, with a wheelbase of 2560mm.

After driving the JAC Refine S3 for so long, I was initially confused about which engine oil to use. Checking the owner's manual, it clearly recommends the 5W-30 grade, preferably fully synthetic, as this viscosity is suitable for the car's 1.5L engine, providing high-temperature resistance and wear protection. After using 5W-30 a few times, I noticed smoother acceleration and slightly lower fuel consumption, averaging around 7L/100km. Remember not to switch to other grades casually—for example, 0W-20 might be too thin, and 10W-40 too thick, potentially causing carbon buildup or increased noise. It's advisable to change the oil every 5,000 km, opting for reputable brands like Shell or Mobil for cost-effectiveness and peace of mind, which can also extend the engine's lifespan to over 100,000 km.

Having repaired cars for over a decade, I've encountered many JAC Refine S3 owners struggling with oil specifications. I must emphasize that 5W-30 is the safest choice—it's manufacturer-recommended, offering quick cold-start viscosity and strong high-temperature protection. Don't compromise quality for cheap alternatives; inferior oil can cause engine cylinder scoring or abnormal noises, potentially costing thousands in repairs. During inspections, I always stress checking the manual's specifications while monitoring the dipstick level to ensure it doesn't exceed the maximum mark. The optimal oil change interval is 8,000 kilometers—either semi-synthetic or full synthetic works well, balancing durability and fuel efficiency. Never overlook this routine maintenance.

As a family user, my JAC Refine S3 has been hassle-free for several years. The recommended oil is 5W-30, and I change it on time every time without any issues. This oil ensures smooth engine operation, prioritizing safety when traveling with kids, and also avoids wasting money on repairs. The replacement interval is around 7,000 kilometers, and choosing regular synthetic oil is cost-effective. Just make sure not to use the wrong viscosity to ensure the car's reliability for long trips.

Attention to technical details! The JAC Refine S3 uses SAE 5W-30 engine oil that meets API SN specifications, offering balanced performance in both low and high temperatures. Based on my research, full synthetic oil performs better—its additives reduce wear noise and improve efficiency, saving 0.5 liters of fuel per 100 kilometers. The key is to check certification standards to ensure compatibility with JAC's engine design. Avoid switching to other specifications casually, as it may affect power output stability.
