[TR] Synthetic Oil Engine Damage

[Chad]

What a bunch of bunk.  That old engine was destined to die due to previous years of mistreatment.
The synthetic oil had nothing to do with it.  I'm surprised Lentinello would write something so preposterous.

Just putting in regular changes of a high detergent oil would have the same effect.  I get really tired of hearing
people blame synthetics for problems that are really due to neglect or mistreatment.

Soapbox mode: off.

One of the Hemmings editors had his engine seize and is blaming it on using
synthetic oil in an engine that had previously only burned regular oil. The
car had 73,000 miles.....mostly all short trip miles. He said "The cylinder
head was covered, not in sludge but with hardened, baked oil. Worse was the
lifter valley area below the intake, as shown in the photo. According to
several sources, the synthetic oil eventually broke up the old, hardened
deposits (thanks to the original owner's short-trip driving style), which
then clogged all the oil galleys and oil pump, which then ruined the
bearings."

Read it all here (http://tinyurl.com/2l7f46) and double click the picture of
the head.....it really is pretty ugly what happened.
