324 Technical termsEngine oil viscosity
Measurement for the inner friction (vis-

better the viscosity.

pendent systems, their protective func-
tions complement one another.RON
(R
esearch O

The Research Octane Number for gaso-
line as determined by a standardized
method. It is an indication of a gaso-
line's ability to resist undesired detona-
tion (knocking). The average of both
the ->MON (Motor Octane Number)
and RON (Research Octane Number) is
posted at the pump, also known as
