No, a diesel fuel nozzle will not fit into an unleaded gasoline tank. Diesel nozzles are designed to be larger than gasoline nozzles to prevent them from being accidentally inserted into gasoline vehicles. This is a safety feature to help avoid filling the wrong type of fuel into your car.
柴油的那个加油枪是塞不进去汽油车的啊。我自己有过脑子短路啥都没想，拿了绿色的Diesel 加油枪想加油。是用不了的。每天加油的人太多了，加油站是知道防着大家没常识或者脑子短路的："Diesel nozzles are wider (about 0.875 inches) than standard gasoline nozzles (about 0.625 inches)."她这个就是在加州，又不是什么奇怪的地方会有不是标准化的加油站。
