The difference between authentic Castrol and imitation Castrol

Imitation castrol is definitely not as good as genuine castrol in performance. For example, there will be a CASKA icon on the panel of the genuine Castrol navigation integrated machine, and the body code is also very detailed. If you don't know how to look at the imitation, you can call the official of Castrol, and then enter the anti-counterfeiting code of Castrol navigation integrated machine to know whether it is genuine Castrol or imitation Castrol.

The price of authentic Castrol is generally around 1500 yuan to 3,500 yuan, mainly due to the different models and the memory of the navigation integrated machine, which leads to different prices. If the genuine CAST navigation integrated machine you see on the Internet costs only a few hundred dollars, the owner doesn't have to think about it. These are basically imitations, don't be greedy and cheap.
