If you want MPG you need to feel the car out to know when to shift. Keep throttle pressure light and accelerate slowly, shift at 2K RPM. Keep it in 6th as much as possible as long as you do not lug the engine. On the highway drive 65-70, no more than 70, use CC, 6th gear. Everyone will go by you driving like this but you will yield the best MPG. You can get pretty good mileage driving a stick this way.

For "normal" to moderate driving I would shift at 3-4K and for spirited driving let it almost red line before shifting. The V6 is a high revving engine and makes it's power at high RPM's- let the engine breathe and rev to get the most out of it.

Have fun with the car- I had a 2011 SS with manual 6 speed and if I drove it lightly as I described above I got about 18 MPG. Spirited about 12-15. I now have a V6 RS, A8 and get about 25 mixed, driving very light footed. You got a great car, lot of fun, practical with the V6 for a balance of fun and economy from pretty good MPG and it uses regualr gas, not premium.
