Replacing your car's engine oil is one of the most important auto maintenance tasks. Clean oil lubricates the motor's moving parts to prevent friction and also dissipate heat. Most auto manufacturers recommend you change your oil every 5,000 to 7,000 miles. Unfortunately, many motorists wait too long between oil changes. Below is a look at what occurs if you don't change your oil.

What Happens to the Oil?

When it's new, engine oil is a translucent golden brown color. Over time, it transforms from a clean, viscous liquid that provides effective lubrication into a sludge that does not. The oil collects dirt, condensation, and tiny metal shavings scraped from the moving engine parts.

It thereby thickens, has difficulty traveling through the engine, and loses its ability to reduce friction or draw away heat. When this happens, engine components can become too hot and suffer permanent damage.

How Does Old Oil Affect the Engine?

Extreme engine heat can result in warped engine parts or a blown head gasket, and this could lead to catastrophic engine failure. However, even before that happens, your car loses efficiency and performance as the engine slogs through the gooey mess running through its system. You'll notice problems with acceleration, and you'll spend more every week on fuel. 

How Does It Affect the Car Warranty?

A new car warranty covers problems that arise due to defects in manufacturing. However, to maintain this coverage, you have to follow some guidelines. One of these is to follow the manufacturer's recommended oil change schedule. Failure to do so could void the warranty and leave you financially responsible for any repair costs that arise—even those that would otherwise be covered by the manufacturer.
