uniquely identify each engine pro-
duced.
Engine oil viscosity
Measurement for the inner friction (vis-
cosity) of the oil at different tempera-
tures. The higher the temperature an
oil can tolerate without becoming thin,
or the lower the temperature it can tol-
erate without becoming viscous, the
better the viscosity.ESP

This very quickly accelerates the vehi-
cle and should not be used for normal
acceleration needs.

(page 272)
Line of fall
The direct line that an object moves
downhill when influenced by the force
of gravity alone. Lock button
