Oh and our temps are 80+ degrees.
You will find lots of friendly advice all over this site; keep in mind that each person's experience with their HyHi is different, and what works for one person may not work for others. That said, I can offer my suggestions on what has worked for me:

- "Learn to drive like an old man." That means no sudden accelerations and sticking to the speed limit where possible. Driving a HyHi efficiently is going to require that you change your driving habits. Flip your display to show you the current MPG value, and watch how your driving style affects that graph. Over time, you will learn how to accelerate or coast to maintain 60-70MPH while maximizing MPG efficiency.

- As others have said, the A/C will have a negligible effect on your MPG. Driving with your windows open, however, can put a drag on your numbers.

- If you use your car for lots of short trips, you will lose efficiency. The engine needs to be warmed up sufficiently before it can start giving you the maximum return.

- Check your tire pressure. Make sure that you're at least at what the HiHy sticker tells you to be at.

- No need to use higher octane gas. That said, 89 or 93 should give you anywhere from a 3%-10% boost in MPH per tank, all other driving things being equal.

It will take more than a few weeks to figure out whether the problem is with the car or with your driving style. It took me over a year to be able to hit an average of 40MPG on my screen (it was there once for all of about 2 minutes, but I'll take what I can get)
