As a # of others have noted, 24-28 mpg in mixed driving seems to be the norm. for the V6. Mine has improved steadily with new plugs, new o2 sensors, K&N OEM air filter, oil & filter change every 3-4K miles,one of those Bomb Mufflers/ebay,actually sounds pretty good so far, like an old Healy6,=less back pressure, and I'm convinced running 90+ gas has helped. I'm curious how long have you had the car, and was your milage ever better?
By the by, the original plugs had 74+K miles and looked like 174K, the O2 sensors had seen better days also. The suggestion to check it out @ the Zone is a good one, unless you have your own code unit, but we wouldn't be having this chat if you did. Seriously it's probably the easiest and cheapest way to answer your question.
