Exceeding the recommended interval for lubricant replacement in an internal combustion engine can lead to a degradation of the oil’s protective properties. Motor oil is designed to lubricate moving parts, dissipate heat, and suspend contaminants. Over time, the oil’s viscosity decreases, its ability to neutralize acids diminishes, and the accumulation of sludge and varnish increases.
Adhering to the manufacturer’s specified oil change schedule is crucial for maintaining engine health and longevity. Regular oil changes ensure optimal lubrication, prevent excessive wear, and reduce the risk of costly engine repairs. Historically, recommended oil change intervals were shorter due to less advanced oil formulations and engine designs; modern synthetic oils and improved engine technologies have extended these intervals in many cases.
