just did a 240 mile roundtrip South bend to grand rapids--- i got 18 going up and 16 coming back using the cruise control and the route was a tad hilly--- viscious headwind of about 35 mph going back-- more of a cross wind going up-- so i really never got the benefit of a tailwind-- i use premium and i just got a service done up there while doing some other stuff--- tires rotated synthetic mobil 1 and i brought them my own filter all for 63 bucks and a decent car wash
4300 miles ( i maybe drive 5000 a year)
