  I completely understand the constraints of an engineer`s job, as I will be
  graduating in May and hope to land a job as one myself.  I admit I lack the
  practical experience, so there is no need to attack me for thinking I am an
  experienced engineer, but I have been taught the necessary considerations and
  have some experience in taking them into account on some projects I've worked on.

  I was not asking GM (or anybody else) to build the perfect car.  However, Val's
  response to my question about aftermarket oil priming systems was one which
  insinuated that there was absolutely no use for such a system because the car
  had already been ** ENGINEERED** to not need one.  He in no way acknowledged the
  fact that indeed such a system could improve the engine life, but may have been
  left out of the original design because of cost considerations.  He simply tried
  to impress us with the word ENGINEERED, and tell us that those who had originally
  designed the car had already though of that, and deemed it a worthless system
  to add to the vehicle.  He also failed to list another reason that such a system
  may not have been added to a vehicle, and that is planned obsolesence.

  I have not read any of Val`s previous posts, and so if there is some predisposed
  attitude that I should know of, I don`t.  Again, I completely understand that
  a designer`s position requires a lot of give and take, but this should be stated
  rather than have to be assumed by such a statement as it was engineered that way.

  Lastly, I know that changing the oil and filter regularly is one of the best things
  one can do to extend the life of their engine.  However, most all bearing wear
  comes from starting the motor, when the bearings are dry.  This wear is even greater
  when it is cold, and the oil tends not to flow real well.  A priming system will
  help reduce that wear upon starting significantly.  This does not only have the
  obvious advantage of extending bearing life, but also has a significant effect
  on other engine parts by keeping the engine "nice and tight" for a longer time.
