"We were told by the car rental company at the time not to add fuel."

This is only for diesel cars. Gasoline cars should not have it.

It's actually a kind of diesel additive, which needs to be added. Note that you need to add the one that can be added with a fuel gun, which is cheap, only about 0.6 euros per liter. You can just add it to the fullest. Don't buy the canned one, which is expensive. The 5 liter one costs 18 euros.
