Bon Ami wob

["Gerald R. Kolb" <jkolb@xxxxxxxxxxxxx>]

Of interest to those of you with a bent for automotive history is the =
fact that the Bon Ami that bimwads are so fond of for windshield =
cleaning, had another very important automotive use many years ago.  =
In the 1955 model year Chevrolet introduced its famous smallblock V8 =
in the 265in. version.  The early production run used oil at the rate =
of 200=AD300 miles per quart.  It was found that this was due to an =
incompatibility between the honing pattern and the piston ring =
material.  The official factory fix communicated to dealers was to =
slowly dump a box of Bon Ami down the carburetor while the engine was =
running.  Seems the Bon Ami helped to polish the cylinder bores, =
providing a better seating surface for the piston rings and =
dramatically reducing oil consumption.

It is wierd to think of what happened to the Bon Ami that got past =
the rings.  Chevy didn't start using a full flow oil filter until =
1957!  Aparently no problems.
