Just picked up a new 2014 Mirage ES five speed this weekend. Got about 41 mpg at 70 mph on my first long commute today.

What kind of options are there for improving mpg? I've read suggestions about tire pressure, removing mirrors, even replacing the 5th gear.

I had been driving an accord V6 6 speed coupe that got about 32 mpg. Got the Mirage because I've got a 150 mile commute every day. The Mirage runs around 3500 rpm at 70 mpg. I find myself looking for that 6th gear!

Thanks!
