Hi Jenny, Karl and Volksfolks,

I found the empty (355ml) bottle of the stuff that was so effective at
quietening my noisy lifter.
the stuff is "petro chemical" brand Tune Up.
Quiets valves and lifters
dissolves harmful deposits.
DIRECTIONS To tune and free lifters while you drive, add entire contents of
bottle to crankcase. To free sticky valves and upper rings, slowly pour
entire contents of bottle through carburettor at fast idle. Entire contents
of bottle to be emptied upon initial opening.
DANGER:CONTAINS BUTYL CELLULOSE AND PETROLEUM DISTILLATES.
Also..petro chemical tune up contains no potential clogging solids -
graphite, carbon tetrochloride, or any harmful ingredients.  MADE IN USA
