To find the average order size, we need to find the total number of gallons purchased and divide it by the number of purchases. So, adding up all the gallons gives: $15+16+13.5+18+8+12=82.5$. Dividing by the number of purchases (6) gives: $82.5/6=13.75$. Therefore, the average order size of gasoline is 13.75 gallons. Therefore, the best choice is (B).
