[Healeys] EOS has been discontinued by GM

[Alan Seigrist]

Hey guys -

Sorry, I have to clear up one thing.

The removal of ZDDP from oil is not because of the "Enviro-Nazis", well at
least not directly.  They are reducing ZDDP content in oil because long term
use has shown that high ZDDP concentrations lead to premature wear and
failure of catalytic converters, which then leads to cars failing their
annual smog certifications.

Of course, as an avowed enviro-nazi myself, I think a 50 year old Bugeye or
my 54 year old 100 is friendlier for the environment than the majority of
modern fleet vehicles simply because they have better mileage.  How is it
that my '53 BN1, a high performance sportscar no less, gets better mileage
than the average US passenger car fleet in 2007???  No wonder the US auto
industry is going down the crapper.

Cheers,

Alan
