A sticker at a particular Ohio gas station that appears to enforce a fueling rule has left Reddit talking. Due to high gas prices, people seem concerned about this sticker, which appears to make it compulsory to buy at least 4 gallons of gas. Recommended VideosIn the shared image, a black sticker with white font can be seen giving refuelers this message. It says, “MINIMUM FUELING VOLUME 4 GALLONS,” and after stating the volume, it appears to warn about the consequences of refueling with a lower amount: “DISPENSING LESS MAY VIOLATE FEDERAL LAW.” This suggests that the 4-gallon fueling rule might be true, but not for all gas stations.
