[TR] Regarding Oil

[Anthony Rhodes]

David,

I was under the impression that ALL street legal oils that have the current
oil quality designation (SM now?) have the low level of zinc, including the
street-legal VR1 Racing. I hope I am wrong since I have a bunch of it.

Only a few years ago, the VR1 Racing oil seemed to be quite good, but then it
did have reasonable amounts of zinc.  I ran out of my old stock of it last
year, and I have the regular new type, plus a few doses of ZDDPplus sitting on
my shelf ready to go for this year's oil changes.

  This highly controversial topic has raised its head again.
  I use Valvoline VR-1 20/50 Racing not the "not street legal" stuff.  Check
this out.

  A couple of points for all to consider when making this decision.  First, a
racing oil that is "not street legal" has a very short sump life and is
intended to be used and dumped with a high frequency.  The reason is; it does
a very good job for a very short (by comparison) time.
  Amounts of ZDDP in excess of 1200 - 1300 ppm are not good for your motor.  I
cannot at the moment put my finger on it but do recall reading, and filing, an
article about ZDDP in oil when it was introduced as the miracle anti wear
additive in the 70's.  Motor damage (not catalytic converter) resulted from
excessively high levels and the additive gained a black eye.
  As a result of this article I chose Valvoline VR-1 20/50 Racing because of
its availability and ZDDP levels in the 1200 - 1300 ppm range.
  I will also add that the only people I know who have lost a cam lobe have
been practicing the witches brew theory of oil additives.  I am not that good
at chemistry as this really hot girl sat next to me in class, so I leave the
decisions to the chemists at Ashland.  Apparently they were more interested in
chemistry than what I was interested in.
