Can I switch from Sinopec to PetroChina?

[McBella]

As long as the octane rating is the same. You can switch from Sinopec to PetroChina gasoline, as long as it meets national standards. Here are the specific differences between PetroChina and Sinopec: 1. Raw materials: Although PetroChina and Sinopec use almost the same processes, the additives are different. Sinopec uses some of the best imported additives in the world. 2. Density: In terms of fuel density, PetroChina's gasoline density is generally around 0.72-0.73, while Sinopec's fuel density is around 0.75-0.77. The quality of both fuels is similar, but PetroChina's fuel density is slightly lower than Sinopec's. 3. Mileage: Since PetroChina's density is lower than Sinopec's, Sinopec's fuel tends to last longer and provide better power, and is generally slightly more expensive. However, since the brands are different, the crude oil, gasoline processing methods, processing procedures, and additive usage also differ. Frequent mixing may cause slight engine vibration, carbon deposits, and other discomfort symptoms.
