Can I add PetroChina oil after adding Sinopec oil?
1 Answers
You can switch to PetroChina oil after using Sinopec oil, as long as the gasoline meets national standards. Below are specific comparisons between PetroChina and Sinopec: 1. Raw materials: Although PetroChina and Sinopec use almost the same processes, their additives differ. Sinopec uses some of the best imported additives available globally. 2. Density: In terms of oil density, PetroChina's gasoline density is generally around 0.72–0.73, while Sinopec's oil density is around 0.75–0.77. The quality of both oils is similar, but PetroChina's oil density is slightly lower than Sinopec's. 3. Mileage: Since PetroChina's density is lower than Sinopec's, Sinopec's fuel tends to be more durable and powerful, and it is usually slightly more expensive. However, due to differences in crude oil sources, gasoline processing methods, procedures, and additive usage between the two brands, frequent mixing may lead to minor engine issues such as slight shaking and carbon buildup.
