In the United States, that product is NOT marketed, at least under that name.
Phillips 66 has a synthetic blend "Trop Artic" product that sells for $1.48/qt in my local Wal-Mart store.
That's about 11.8 Chinese Yuan Renminbi.
Motorcraft is made by Conoco and sells for $2.3/qt in a local parts store.
That's about 18.5 Chinese Yuan Renminbi
Most Conoco synthetic blends are more pricy than Trop Artic, but my local store doesn't carry them, or I don't remember them.
As far as a full synthetic goes, I also don't have that available locally from a Conoco brand..
