I bought a used 04 Sequoia 4x4 Ltd with 48k miles recently. When I First rolled it off the dealership's lot (a Toyota dealer) the thing was getting 14MPG. I replaced the o2 sensors, plugs, wires and electronic distributor, rotated the tires, replaced the oil and filter, air filter, and fuel filter. Total cost was about $250 in parts and an afternoon of my time.

I'm now getting 21.5MPG highway and 17 city.

Routine maintenance is key for continued good performance. I change my oil every 3k miles or 60-days, make sure the tires get rotated and have the right pressure, and hose it off when I get back from off-roading (I put about 1k miles a month on it on dirt roads in mid western Maine).
