... These laws are so simple that one can easily be deceived by how revolutionary they were. They are (in Newton’s own words): Law #1: Every body continues in its state of rest, or of uniform motion in a right line, unless it is compelled to change that state by forces imposed on it. Law #2: The change ...

Lubricants reduce friction, and less friction means that the engine and the wheels move more smoothly (and stay cooler). This means the engine needs to exert less force, which often results in in lasting lon ...
