Which is better, Tan Invincible Engine Oil or Huayi Jinwei?

Huayi Jinwei is better. According to relevant public information, Huayi Jinwei is applicable to all models, while Tan Invincible Engine Oil is only applicable to individual models. As a protective agent, Huayi Jinwei added a protective film on the basis of lubricating oil, which greatly improved the lubrication efficiency. Engine protective agent can effectively lubricate the engine and enhance the quality and durability of engine oil, but Tan Invincible Engine Oil has no such protective film.
