How is the quality of Defu engine oil?
2 Answers
Defu engine oil is good. Synthetic products are developed through chemical reactions that carefully control pressure, temperature, and the proportion of component elements. This produces pure compounds that enhance lubrication properties, thereby promoting energy-saving benefits, improving equipment protection, enhancing equipment reliability, and extending the service life of the oil. Here is its related introduction: Summer models: High-temperature types for summer use, 20, 30, 40, 50. The larger the number, the higher the viscosity, and the higher the maximum applicable temperature. Winter models: Low-temperature types for winter use, 0W, 5W, 10W, 15W, 20W, 25W. The symbol W after the number represents Winter, and the smaller the number before W, the lower the low-temperature viscosity, the better the low-temperature fluidity, and the lower the minimum applicable temperature.
Defu engine oil has performed well in my daily car use. As a veteran driver with over a decade of experience, I've tried many oil brands, and Defu's synthetic oil has shown noticeable improvements in my Toyota: reduced engine noise, smoother acceleration, and more stable fuel consumption. The oil change interval is quite long, requiring replacement only every 8,000 kilometers, which saves a lot on maintenance costs. The key is to check its certifications—Defu usually has API certification, indicating the oil meets quality standards and effectively prevents carbon buildup and engine wear. Of course, poor-quality oil can cause engine overheating or failure, but Defu has never given me such concerns. Overall, it offers great value—affordable price and reliable performance—making it a good choice for practical drivers like me. However, before purchasing, I recommend checking the packaging labels to ensure authenticity and avoid counterfeit products that could harm your car's lifespan.
