关于DOLLAR租车强制买一箱油的问题

看到很多前辈都说如果在订车时选Inclusive no Excess等不含Initial Tank of Petrol的Package，在租车柜台会强制性要求买一箱高价油，不知道有没有人不买这箱油租到车的？如果要买这箱油，一般多少钱（以Ford Escape为例）。

我自己2次选Inclusive Package，JS都极力推荐的样子就买了油，不过英文不好，不知道是否是强制条款，2次都是Compact的车，记得都是45刀左右的油费。

查了下美国Dollar的网站上关于油费的规则如下，好像意思并不是强制的。


I. Gasoline Policy: The renter must refill the gas tank of the vehicle within a 10-mile radius of the rental return facility and present a fuel receipt to avoid a refueling charge unless the renter chooses the prepaid fuel option. If the renter chooses the prepaid fuel option, the renter will pay a specified charge as set forth in the rental agreement and have no obligation to return the vehicle with a full tank of fuel. There is no credit or refund given for any fuel in the tank at the end of the rental. If the renter does not choose the prepaid fuel option and does not return the vehicle with a full tank of gas, the renter will be required to pay a fuel charge to compensate DOLLAR for the cost and service of refueling the vehicle.
