SANTO DOMINGO.- The Industry and Commerce Ministry posted no changes in the prices for gasoline, diesel, liquefied petroleum gas, avtur and kerosene
For the week from Saturday, July 25 to Friday 31 premium gasoline will cost RD$144.90 per gallon, and regular will cost RD$135.20
Regular diesel will cost RD$108.40 per gallon, and premium diesel will cost RD$113.40.
Avtur will cost RD$85.64 per gallon, and kerosene will cost RD$102.20, whereas liquefied petroleum gas (propane) will cost RD$57.54 per gallon.

when the gas was over $4 in USA last year, it was over $6 in DR. It seems like there is a $2 per gallon delivery charge. lol
If you don't know why Gas is more expensive in the DR than in the US may I suggest a visit to a Library and check out some basic economics books.
