I guess I must be lucky!
My worst milage so far has been 24.5 and the best 28 mpg. I don't drive like a age challanged female (being PC [
]) and my PT is an auto, so I don't understand the mpg difference.
I haven't modified my engine at all, I did go to Mobil-1 but no real diff there, and I have ordered a K&N filter off of E-Bay that CREWZIN missed[B)]. Hope that helps some.
