My 2010 HS has been dropping gas mileage steadily. Went from about 37 to now about 30 in a week. Is gas mileage lower in the morning when your car hasn't been driven? Should I inflate my tires above the recommended 32psi? Thanks.

Did you have a significant change in the weather? Fill up at a different gas station? Change your driving pattern? If all of the above are "no", then that's quite a change. I assume you did check your tire pressures to ensure you don't have one going flat. Also check your wheels after you've driven - if any are really hot, then you have a sticking brake caliper. Could also be a clogged air filter, or water in the gas tank.

If you go another tank and it's still 30, and feel you haven't significantly changed anything about how you drive from when you were getting 37, then I'd take it in and have it checked.
