Lubrication Works by Keeping Surfaces Apart
Lube is short for lubricant. Its job is to stop two surfaces from touching at all.
Lube is an informal shortening of *lubricant*, a substance reducing friction between surfaces. A good lubricant does not make surfaces slippery so much as separate them: under load the oil forms a film thinner than a human hair, and the moving parts ride on that film without metal ever touching metal. Wear happens mainly when the film breaks down, which is why starting a cold engine causes most of its lifetime damage. Latin *lubricus* means slippery.

Why cold starts cause wear
- Oil drains down while an engine sits
- On starting, surfaces briefly run with little film
- Cold oil is thicker and slower to reach the top of the engine
- Most engine wear happens in those first seconds
- Modern oils are formulated to cling and flow quickly when cold
Short for *lubricant*, from Latin *lubricare*, to make slippery, from *lubricus*.
How does a lubricant work?
It forms a film that keeps surfaces apart, so moving parts ride on the fluid rather than touching each other.
Why are cold starts hard on an engine?
Oil drains down while the engine sits, so surfaces run briefly with little film until pressure builds again.
