Can You Mix Gasoline from Different Gas Stations?

[LaAlexis]

You can mix gasoline from different gas stations as long as the octane rating is the same, but make sure to refuel at reputable gas stations. There may be slight differences in fuel quality between different gas stations due to varying sources of crude oil, but refineries produce gasoline according to national standards, so even if the octane values differ slightly, the variation is minimal. It is recommended that car owners follow the fuel grade indicated on the fuel tank cap when refueling. When selecting engine oil, strictly adhere to the oil grade specified for your vehicle. If the same grade is unavailable, you may use a higher-grade oil, but never substitute with a lower-grade oil to avoid engine knocking.
