Always go with manufacture schedule. If there's anybody that don't
have to screw up their car it's them. If they feel that making you
change early would make their car lasts longer they would of say so.
Since they didn't, you can bet that you really don't need to change it
early.

It's hard to deal with paradigm shifts, but technology does improve.
This country took 30 years to get people away from the 1,500 miles oil
change interval to convince them that they really only needed to
change oil every 3,000 miles. Now it seems like it will take equally
long before people really believe that you can last 5,000 miles
between intervals on regular conventional oil.


That is not entirely true. The marketing and sales people have a significant
determination in what the maintenance intervals are (since warranty costs
comes out of their budget). Marketing and sales looks very closely at what
the competition says, because maintenance schedules can be a competitive
advantage when trying to sell one brand over another. So it is not entirely
an engineering decision as one might think.
