[T3] fuel mileage is too good?

["Ginger D.&Peter P." <gingerd@teleport.com>]

    I keep a notebook in the glove box, and have recorded gas mileage
for 4 years.  The last 4 tankfulls have seen a steady increase in
mileage, but I can't find a good reason for it.  I've always noted
better mileage equals a better state of tune, but now I've noticed a
strange phenomena.
    For three months my normal 80% city driving and 20% hwy commute
has been steady at 22-24 mpg.  I then recorded a 25 mpg and then a 26
mpg, w/o a drastic change in city/hwy.  I've never gotten over 26 mpg
before today.  After a 160 mile hwy road trip to Mt. Hood and back I
got 28 mpg!  The car still runs the same, and the only maintenance
done was topping off with a 1/2 quart of oil after the 25 mpg fillup.
    What's going on?  I'm worried I might run too lean and burn up a
head.
