your mpg is so good for 4.44 to me when i drive my 4.44 on the highway, i average 21+mpg only but my speed is 80-95-- on hilly highway

On highways I average 70 and the highest I usually go is 75.... that's probably why .... Also when accelerating I usually try to never gas it above 2500 RPM and thats usually how i save gas... although it's hard to resist that urge...
