With many ecomods and slow, careful driving, my '04 auto Civic had a best highway trip of a hair over 60 MPG for over 300 miles. To get that kind of mileage in the city required extreme hypermiling techniques.

To beat the auto's highway fuel economy you would need to use a taller geared transmission.
Thank you, that's pretty much what I thought. Oh and btw 60 MPG highway is seriously amazing, the most I ever got on the highway was around 40.

I am not going to go with the LX or HX manual trans, so I guess the best I can do is get the EX trans and swap to an HX 5th gear.
