When the indicator nears empty, you still have a little fuel left, but you should get more soon. Here are four things owners usually ask about the fuel gage. All these situations are normal and do not indicate a problem with the fuel gage: At the gas station, the pump shuts off before the gage reads full. It takes more (or less) fuel to fill up than the gage indicates. For example, the gage reads half full, but it took more (or less) than half the tank's capacity to fill it.
