OK because I am having periodic power lose and stalling (possible fuel pump or filter) I put 93 octane($30 ) in which I just regularly use the mid grade. Now I go and deliver my big paper route (Constant stop and Go) and after I was done this morning I filled up again. To my suprise I am getting 29MPG. Which just last week doing my paper route(Constant stop and Go) I was getting 16-19MPG. I also have a hole in my Y-Pipe. Maybe I will start putting in 93 more often.

 

i was getting 26MPG last week....i wasnt doing anything different. must be the weather.

 

Do you always fill up at the same station? Ive realized if I change stations, I get better milage. If I fill up at the same station more than once, the milage goes down. Almost seems as if my Max gets used to the certain type of gas.
