Can engine oils from different gas stations be mixed?
1 Answers
Engine oils from different gas stations can be mixed as long as they have the same grade. However, it is important to refuel at reputable gas stations. There may be some differences in fuel quality between different gas stations because their sources vary, but all refineries produce oil according to national standards. Even if the octane ratings differ slightly, the variations are generally minimal. The fuel sold at gas stations must meet the national quality standards. For some off-brand gas stations, cheap fuel should never be used—despite the low price, it can cause significant damage to your vehicle. Therefore, always ensure you refuel at reputable gas stations.
