[TR] Regarding Oil

[Wbeech@flash.net]

David,
When you say "...has a very short sump life.." what length of time or mile
are you referring to?  My car is a fair-weather-on-the-weekends driver that
probably won't see more than 2,000 miles in any given year.

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.
