Best options for rental car refueling near Paris CDG?
 

The few times I've had this need, I haven't seemed to be able to find a close and easy-to-find spot. Suggestions welcome.

There is a gas station on the CDG entrance road. It would be rather difficult to miss.

With most cars, you can drive 40-80km before a full fuel gauge moves down. Since my aim is not to actually cheat the rental company, I would never go 80km, but I often fill up 20-30km from the rental car return if I am not sure what I will find in an unknown area.

Europcar is really very lucky with me because nearly all of my cars are returned to Paris-Gare du Nord and I fill the tank less than one kilometer from the agency at the very cheap Esso Express at Place du Colonel Fabien.

I've used the one quite close to CDG; my guess is that it's about 1 miles or less from the terminal. I would describe its location as being on the median between the eastbound and westbound lanes, so be in the left lane approaching the terminal. When I first saw it, I was surprised at it being so close, as I could see the terminal in the distance. I had just about given up on finding a station, and was prepared to go beyond the airport in order to get gas...and then there it was! I don't recall the price per liter being exorbitant, either; certainly cheaper than what I would have paid the rental firm to refuel it.
