Draining the Old Oil Locate the oil drain plug underneath the engine, place the catch basin beneath it, and carefully loosen the plug by turning it counterclockwise. Over time, however, these suspended particles overload the oil, and its additives break down, reducing lubrication efficiency and increasing the risk of overheating.

A sturdy jack and jack rated for the vehicle’s weight, along with a catch basin large enough to hold the used fluid, are essential. The number before the "W" indicates cold-flow performance, ensuring the oil reaches critical components immediately on startup, while the number after the "W" reflects thickness at operating temperature.
Conventional lubricants are refined from crude oil and provide adequate protection for average driving conditions and older engines with looser tolerances. While full synthetic usually carries a higher upfront cost, it can reduce long-term maintenance by allowing longer intervals between changes and offering superior protection during severe driving conditions such as towing or frequent stop-and-go traffic.

Modern formulations include detergents that keep internal surfaces clean, dispersants that prevent sludge from clumping together, and viscosity index improvers that maintain consistent flow in both cold startups and high-temperature operation. Understanding How Oil Protects Your Engine Motor oil is engineered to do far more than simply reduce friction between pistons and cylinder walls.
