My car is a Land Rover diesel version, which has nothing to do with running a wedding. The original engine oil was used before, and its performance was not good, but to be honest, there are not many high-quality diesel engine oils in China. Later, I changed the German GT oil. Although this oil is less, its performance is much better than before, and its maintenance cycle is still very long. It can run 14500 km every time the oil is changed.
