近日，一则‘68升油箱被加74升油’的新闻引发广泛关注。车主在加油站加油时，发现车辆标注油箱容积为68升，却实际加注了74升汽油，超出标称容量6升，因此质疑加油站存在计量作弊行为。对此，专家解释称，汽车制造商标注的油箱容积通常为‘安全容积’或‘额定容积’，并不包括油箱上部用于油气膨胀的缓冲空间。实际油箱总容积往往比标称值多出5%至10%，以防止高温或行驶中燃油膨胀导致溢出。因此，在油箱完全耗尽的情况下，确实可能加入超过标称容量的燃油。此外，加油枪采用高精度流量计，国家对加油站计量设备有严格监管，定期校验，一般不会出现大规模作弊现象。若车主仍有疑虑，可向市场监管部门申请检测加油机是否合规。总之，‘加超’现象虽令人困惑，但在技术层面是合理的，并不必然代表加油站存在欺诈行为。消费者应理性看待，必要时通过正规渠道维权。
Recently, a news story about a ’68-liter fuel tank being filled with 74 liters of gasoline’ has drawn widespread attention. The car owner noticed that although the vehicle’s fuel tank is labeled as having a 68-liter capacity, the pump dispensed 74 liters—6 liters more than stated—prompting suspicion of metering fraud at the gas station.Experts clarified that the capacity indicated by automakers usually refers to the ‘safe’ or ‘rated’ volume, excluding the additional space reserved in the tank for fuel vapor expansion. In reality, total tank capacity often exceeds the labeled figure by 5% to 10% to prevent overflow caused by thermal expansion or motion during driving. Thus, if the tank is completely empty, it is technically possible to add more fuel than the nominal capacity.Moreover, fuel pumps are equipped with high-precision flow meters and are subject to strict national regulations and regular calibration. Large-scale metering fraud is therefore unlikely. If concerns persist, consumers can request an official inspection from market regulatory authorities.In summary, while overfilling beyond the stated capacity may seem puzzling, it is technically plausible and does not necessarily indicate fraudulent behavior by the gas station. Consumers should approach such cases rationally and seek formal channels for verification if needed.
