He make shis living changing oil. What do you expect him to say?


What's the better experience?
You got your stories, I got mine.

The better experience is my own evaluation of my own driving habits and
conditions as well as reading what the manufacturer of the engine and
testing laboratories conclude. Short distance driving in cold weather?

Yes, if you _only_ do short distances, you build up moisture in the oil
system which doesn't get vaporized by engine heat. But short trips with
occasional longer trips and freeway driving gets rid of that moisture.

All the experts agree that 3000 mile oil changes are almost always
unnecessary for normal service.

There are sometimes side benefits to the 3000 mile changes, such as when
people have an oil burning engine yet never check or top off their oil.
The 3000 mile oil changes mean that they'll have a lot more oil in their
engine, on average, than if they did 7500 mile changes. There were some
Saturn engines where the oil needed to be exceptionally clean because it
was used to hydraulically to tension the timing chain. Varnish build-up
in the timing chain tensioner bore could cause the tensioner mechanism
to malfunction, and lead to timing chain failure. But these sorts of
issues are pretty rare.
