99 lincoln continental fuel economy tweaks by teufelhund

I have a 99 continental with 70k miles that is averaging 26.5 mpg.When I don't take the bus and light rail I'm commuting 84 miles round trip so it is mostly highway. Not as good as the 32mpg I got a few years ago.
 
I am reading a lot about how to tweak more mpg and looking for suggestions from other continental owners. Today I changed the air filter, fuel filter, took 82lbs of junk out, washed it, filled the tires up a bit and started looking at 270 instead of 275s for the tires. I also dumped in some slick 50 snake oil for fuel injector cleaning. I doubt it does anything but it feels good like buying a lottery ticket. I'll post back on what I get for this week after 320 miles.
 
Has anyone tried a new cold air intake? Exhaust? New spark plugs? How do you get to the spark plugs? Any other ideas? Can someone make a carbon fiber hood for me?

So my tires are 225 not 275. oops.
 
Last week up to today I'm averaging 32.1mpg. That is going a mile to the highway, about 40 miles at mostly 55mph with no stops and then half a mile to my parking lot. I drafted a semi for about 14 miles too. Cheating every chance I get to bring it up.
 
Anyone have any other ideas? I read that synthetic oil might boost it a little? What about a new computer? Can you use one from a mustang with the same engine?
