Pistons travel up and down at incredible velocities, while the crankshaft spins rapidly beneath them. The additives in motor oil keep these materials supple, preventing them from drying out, cracking, or shrinking.
How Low Oil Levels Lead to Serious Engine Damage
The oil pump circulates oil through galleries and into bearings, ensuring that a continuous film separates these surfaces. It flows quickly during startup to provide immediate lubrication when the engine is most vulnerable, and maintains sufficient thickness at operating temperature to protect under heavy loads.
Oil suspends these contaminants, carrying them to the oil filter where they are trapped. Every combustion under the hood of your vehicle relies on a thin, golden film of lubrication.
How Low Oil Levels Lead to Expensive Engine Damage
Managing Heat and Engine Temperature Heat is the enemy of internal components. These gaskets and o-rings require constant conditioning to remain flexible and impermeable.
