Engine oil doesn't just get dirty over time—its protective additives actually get used up through chemical reactions. Detergent additives sacrifice themselves by neutralizing acidic combustion byproducts, while anti-wear additives bond to metal surfaces and gradually wear away with use. This is why even perfectly clean-looking oil that's been filtered can still be "worn out" and need changing. Modern oil analysis can measure the remaining additive levels to determine if oil still has protective life left, potentially extending change intervals safely.
