This heat not only accelerates the wear on engine parts but also causes further oxidation, creating a vicious cycle where the oil degrades even faster. Driving with old oil is akin to sanding down the interior surfaces of your engine, causing clearances to increase.
Thermal Stability Lost as Old Oil Fails to Protect Engine Components
Long-Term Consequences and Financial Impact The financial implications of skipping oil changes are severe and far outweigh the cost of routine maintenance. As oil circulates, it collects microscopic metal shavings, dust, and chemical byproducts of combustion.
Without this protective layer, metal-to-metal contact occurs, creating friction that rapidly generates excess heat. When this happens, the oil film between components like the pistons and cylinder walls becomes thin or even breaks entirely.

The result is a significant reduction in the engine’s ability to regulate its internal temperature, which can lead to overheating and warped components. Warning Signs to Watch For.
