I like filing in my gas here for the reason that it's location is close to work. However if you…read moredon't know the entrance, it's a little bit tricky to get to, as the sign can be seen from the road, but you have to drive around Delhaize to get to it.
Also the gas station location in the cargo side of the airport means that you encounter a lot of huge line haul trucks, who are also filling gas, however it's good because they have a separate filling station (the first two lanes are reserved for them, and the next three for cars).
One final tip - some of the Gas pumps are Bancontact only (nos 12, I am looking at you), so look and check what payment options are available to you! Oh also - there is English language option available during payment!
