Can Synthetic Engine Oil Still Be Used After 13,000 Kilometers?
1 Answers
It is recommended to change the synthetic engine oil promptly after driving 13,000 kilometers. Failing to do so may cause damage to the car engine and shorten its service life. Below is relevant information about synthetic engine oil: 1. Introduction: Synthetic engine oil is manufactured through chemical synthesis by humans. Depending on the intended use, the composition of synthetic engine oil can be adjusted. The development of synthetic engine oil began in the 1930s. At that time, due to the demanding conditions of aircraft engine oil use, there was a need for higher-performance engine oil, prompting some chemical plants to start developing and producing synthetic engine oil. With the rapid advancement of modern chemical technology, the performance of synthetic engine oil has significantly improved since the 1990s. 2. Features and Classification: Synthetic engine oil is a product of modern chemical technology progress. It offers numerous advantages, such as higher lubricity than mineral oil, lower friction resistance, better oxidation resistance, and stronger cleaning properties. Semi-synthetic and full-synthetic engine oils are two classifications of engine oil (full-synthetic engine oil contains no mineral oil components, while semi-synthetic has some). The main difference between them is that full-synthetic oil can operate over a wider temperature range and has a longer service life. For the same oil film requirements, full-synthetic oil can achieve the desired performance with lower viscosity, whereas semi-synthetic oil requires a relatively higher viscosity to meet the same requirements. In other words, under the same working conditions, full-synthetic oil can protect the engine with lower viscosity. Full-synthetic engine oil has the following characteristics compared to semi-synthetic engine oil: better high and low-temperature performance, longer oil change intervals, and suitability for more severe driving conditions.
