Oil Sample Analysis Test
Results
Long Beach Transit System
The following
reports reflect Engine
and Transmission results from both the untreated
fleet and treated
fleet.
In order to do like-comparisons for
statistical significance In any test, samples were equally taken.
For example,
this analysis used (6) oil samples in
total; (3) oil analysis samples taken before the treatment; and (3)
oil analysis
samples
taken after the treatment. For the untreated fleet,
the same time frame was used to evaluate the
same
number
of
oil samples
as the treated one. This evaluation method meets the
test of statistics.
The results presented in this report
do reflect statistical significance In the reduction of metal wear
In both major
components tested (Transmission and
Engines).
In
summary, the metal wear reduction results were so significant
that LBTS treated the entire
fleet.
