Not to mention some big, heavy bags and some (ahem) big, heavy passengers. Thank you for your explanation.

Timing belt change. Got it. Thank you, Lenore.

You are the best. Thank you for your response and wisdom. Much appreciated.

I'm smiling about this. Thank you, Lenore. Kinda figured this. I intuitively drive slowly in town, and have noticed good mileage under those terms. By the way, how can you tell if you need new shocks/struts? I'm seeking a smoother ride. Seemed like we felt more NYC potholes than we should have on this trip.

Went on a very long - 4,000 mile - journey for graduation two weeks ago. Drove from Texas to the east coast and back again. In evey non-hybrid car I've had, the mpg rate would always increase with highway driving. No so with the RX 400h (2007). It started out a with a wonderful 27.4 mpg… and kept dropping by tenths as we went along. Now, it has rested at 26.9. I can notice this mpg decrease in my everyday driving. What happened? Can it be improved? I changed the oil and cleaned out the air filter immediately after my return. Does it need a tune up? We've got 95,000 miles on it now. Thanks for your advice.
