I have an 07 Nissan Altima, 2.5 6 speed manual that delkivers 36 MPG highway. This car is basically maintenance free. Can’t say enough about it! I wish GM could come up with something as good.....

Sounds like you are getting better mileage with the bigger engine,and the extra gear.

If mileage is comparable, one should be better off with a larger engine, since it won't need to be working as hard.
