Smell of Castrol

["William E. Irwin" <CigrBill@concentric.net>]

A visit to the pits at Road America in the early 60s got me started on
my everlasting affair with "real" sports cars.

Their looks, the sounds an especially their odor.  I loved the smell of
Castrol and used it continuously for over thirty years.

But the smell is gone from Castrol.

Does anyone know hw I can recreate that beautiful smell.

I have tried adding 1/2 pint of straight castor oil to my crankcase, but
it didn't do anything.

Does anyone have any ideas?
