RE: [VN] New Mobil1 vs. Old Mobil1 vs. Non-Synthetic?

One Thing many may have not thought about is seal life.  I have an article
from wards auto world.. nov or dec that talks about synthetics.  One major
downfall they found is that they found synthetics then to react to most
seals used in new cars.  Also it does not tend to keep seals moist and
prevent drying up of seals like conventional oils

Just another tid bit...

Non-Synthetic?

	I hate to be the one to throw water on the synthetic fire, but let's
	remember that synthetic oil cannot work miracles.  I have an '85
Buick Regal
	that has had 20-50 Mobil 1 synthetic in it since about 20,000 miles,
up to
	its current 102,000.  The oil and filter were changed every 4000
miles.  The
	engine, frankly, is getting noisy.  In fact, I am a little
disappointed in
	how noisy it has gotten considering the expense of Mobil 1.  I am
not
	running a fleet, so I cannot attest to the value of using synthetic
	lubricant, but I have had engines with non-synthetic oil which
lasted
	better.

	Synthetic, no doubt, is better regarding engine deposits, and
thermal
	breakdown.  It's value for reducing wear in on the road conditions
(ie. not
	racing), however, is questionable in my mind.  In fact, I have not
seen one
	good fleet test with a true A/B comparison, with one set of cars
running
	synthetic, and the other running non-synthetic, under the same usage
	conditions.  If someone has seen such a test, I would be interested
in
	seeing it.
