My old Taurus would get 34MPG running at 65 on the highway.
Mine has 3.82 final drive ratio, so I am north of 3k rpm at 80. I am fairly certain the noise is coming from the engine. If I pop it into neutral and coast it quiets right down. No exhaust leaks or other excessive noise at idle or at lower speeds... I think it's just winding it out.

If I drive 65 I can get 33 out of my mixed driving commute. I'd imagine that means mid to high 30s on the highway. I don't have an ultra gauge yet, but empirically I have discovered that I get around 30 driving normal speeds.
