P shirkey I get about the same with my Tbird and my camaro but after that 1st 1/4 tank it just sucks down, Drive a full tank and then figure it out. It could just be that first 1/4 that looks good. After a full tank it averages to about 17mpg hiway and 15mpg in the Tbird and 16 and 14 in the camaro.1949 Plymouth Club Coupe Still in pieces.
