The manufacturer of this engine oil is Shunchang Lubricant (Guangdong) Co., Ltd., located in Xinhui District, Jiangmen City. It is a joint venture between UMW Group in Malaysia and Dachang Bank in Hong Kong. The engine oil is newly produced.
Shunchang has its own brand of lubricating oil, GRANTT Lubrication, which includes automotive oil, industrial oil and cutting fluid, but automotive oil accounts for the vast majority.
Repsol, the general agent of UMW Group in China, is produced by Shunchang in China, but there is a team in charge of its operation in Guangzhou.
