MPG sudden drop

anyone have any idea why i just started to lose 60 miles to the tank? I change my oil every 2500 miles with Mobil 1 and use fuel system cleaner/treatment almost as often. I just all of a sudden lost 60 miles to the tank, no matter what octane I use. TIA, Justin

Think simple fuel leak, needs new air filter,needs a tune-up, O2 sensor or etc.
It could be many things.

If it is just recent, some states have oxygenated fuel that is not as efficient and requires more fuel to get the O2 sensors to get the mix right.

Check your tailpipe. Is there more carbon that usual? If so, it's probably the O2 sensor. That's exactly the failure that I had on my car a few years back.
