<misc>RE: Oil Service

[Ron Browne <r_browne@xxxxxxxxx>]

It was written:

While you can probably wait a bit on inspection I, the oil change is
more
critical.  Changing oil regularly at 3K miles is suggested to ensure
long
engine life, but the service level indicators say about9-10K, way to
long.

===============================

Way too long according to..???  Suggested by which authority? On what
date?  Jiffy Lube and other quick lube places who stand to lose
billions if folks change their 1970 oil change habits to conform to
modern engines, much better combustion processing, and modern much
improved oils, particularly synthetics?

If you have not been keeping up, BMW ain't the only auto manufacturer
to dispose of this 3000 mile or die mentality.  Check out an owners
manual for a new Mercedes or Porsche...on at least one of those, if I
recall, you will see a 15,000 mile interval (using approved
synthetics) recommendation.  I recently read somewhere that GM is
planning to go to a Service Indicator type setup as well, so that
individual needs are taken into account, as opposed to some flat
generalized estimate.  And no, I personally don't believe this is A)a
conspiracy by automakers to increase their rebuilt engine sales and
B)an effort to falsely increase maintenance intervals to satisfy Joe
Carbuyer, the consumer.  I think engineers have determined that modern
lubricants and modern engines are much better today than 20 years ago.
