It has been a while since I posted gas prices in David. This was the price as of Saturday. Remember that prices in Panama are by the liter and that the octane uses European standard. Therefore 91 in Panama is 87 octane in the US and 95 is 91octane.
The 91 octane would be $4.13/gallon and the 95 would be $4.34/gallon. Diesel would be $3.65/gallon.
