  I always cringe when I hear people say that you should follow the 
manufacturer's guidlines for when to change the oil and filter.  First,
whenever you change the oil, you *must* change the filter too, even if it
isn't plugged solid.  The oil filter will hold about a quart of dirty oil,
which will defeat the whole purpose of changing the oil.  It will only
contaminate the old oil.  The old myth about "it's ok to change the filter
every other time" is just that, a myth.
   Second, you should *NEVER*, yes, *NEVER*, follow the manufacturer's 
recommendations on the amout of mileage between oil changes.  Many car
manufacturers suggest changing the oil around 10,000 miles.  To anyone
that knows about engine wear, this is rediculous!  You should *never*
leave the same oil in the car for more that 3,000 *maximum*.  For many
smaller engines, it is wise to change it every 2500 miles.  I know it
sounds like a pain in the neck to chage the oil that often, but when 
your car gets up around 70,000 miles, you'll see how it pays off.  My car
(a Toyota Corolla SR-5) has 94,000 miles on it and still has yet to
use (ie burn, leak) a drop of oil...
