WEX cards are available with each rental, and may be used to refuel the rented vehicles for added convenience. WEX card usage is optional, and renters are welcome to use other methods for refueling. Charges accrued on the WEX card will be billed directly to the renting department "at cost." There is no added surcharge to use the refueling card.
Since WEX cards are through CSU's account, there is a small tax deduction applied automatically when refueling at stations using WEX cards. This discount may not be seen on the pump, but will be applied to the renter's final statement of charges of all rental activity.
A map of locations that use the WEX card can be found here. The BP service station at 900 Carnegie Ave, Cleveland, OH 44115 is the closest WEX card refueling location to CSU.
