I just got back last week also. Honestly, in the three weeks we were there, i filled up twice....once when the light was on, and that was at the Texaco station across from the big grande marche at the circle. I was very pleasantly surprised when was charged only 40 bucks...and it was filled to the brim. Second fill was at the Sol station in Simpson Bay on our way to return the car. The light wasn't on yet, but it cost me 40 bucks then too. I have heard from different people during our years of staying, that the gas on the french side is more ''watered'' down than the Dutch side. Is it??? I really don't know, but usually buy it on the dutch side, and don't shop price, because i figure the difference would be very small.
