One of the most common things is the fuel pressure regulator. The vacuum diaphragm inside leaks and you suck a ton of gas into the intake manifold through the vacuum line. You'll be able to see gas inside the vacuum line to the regulator if that's it. A clogged cat can also take 40% off your mileage and power.
Hopefully you have sense enough not to listen to some halfwit telling you to buy premium.
