The two have nothing to do with each other or, as Yuefu claims, they are just oil bought from Sinopec.

Sinopec uses leading refinery technology, coupled with the advantages of imported crude oil, so that the density of Sinopec’s gasoline is higher than that of PetroChina.

The density of Sinopec’s gasoline is about 0.76±0.01, and the density of PetroChina’s gasoline is about 0.72 to 0.73. The higher the density of gasoline, the greater the driving force of the car. In other words, Sinopec's automotive gasoline is more resistant to burning than PetroChina.
