Worrying about getting ripped off at a gas station should be the least of your worries if you are renting a car and driving in this country if you have never done it before. Fill up when your tank gets below a half and ask for uno mil regular. He will tell you to check the pump is set at zero. For this amount you should get between four and five gallons of gas, enough to go about 100 miles or so. They will also check your water and oil and wash your window. There is no need to get out of your car. When you pull into the station, an attendant will direct you to the appropriate pump. The people here are generally honest and courteous.
You do need to be aware of some typical roadside scams...a car may flag you down or pull up next to you and tell you something is wrong. They might offer to fix it or just rob you. Only stop if you have blow out or flat and be cautious.
Driving here is really the challenge and if you've never driven outside Canada, I wouldn't actually recommend it. The drivers are not predictable. They do not follow passing rules, lines or logic. They tend to be bullies and are always in a hurry. You need to be aggressive enough to survive but allow lots and lots of stopping and maneuvering room. You cannot tell when someone or something will cut in front of you to turn left from a right hand lane or stop for no reason. Also, you'll find that passing on the right or left is normal, especially for motorcycles. And Dominicans tend to drive in the left lane except on major four-lane divided highways because local traffic often stops in the right lane to pickup or discharge passengers.
It might be cheaper and easier to hire a driver to escort you from location to location, especially if you are not fluent in Spanish. The driver will know where to take you to eat and shop and where is safe. Please consider it!
Best of luck on your trip!
