In recent years, there are a lot more engine oils available in China, and the brands are also diverse. Personally, I like playing with cars very much and have changed a lot. There are too many fake shells that go straight past. Say something minority, I can give you reference. Personally, I first changed Anceaux's signature version. I liked YYP at first, but the actual effect in Anceaux is very poor, which is not in line with the price. Then change to FOSS oil, which is noisy and weak in power. After that, I used imported GT engine oil, which was slightly better. I bought it in GT official website, and the oil quality is very clear. The power is pleasant and the fidelity is no problem. Others use Korean engine oil. I personally don't remember the brand, but it's very spicy. The oil of Korean bonzi is not good.
