What Does Motor Oil Do?

Most people know they have to periodically change the oil in their automobile. However, not everyone knows why they have to or what the oil does. Monitoring your car’s motor oil is profoundly important to maintaining your car’s health. If oil goes unchanged for too long, it loses its effectiveness. Old oil can cause all kinds of problems in an engine, from increased wear and tear to allowing rust to form.

One of the easiest ways to maintain a car’s engine is to keep up with oil changes. A used car’s lifespan will be extended drastically if you keep its engine nicely lubricated. If you’re in the market for used cars in Austin, the Austin used car dealers of Chapman Motor Sales can help you find exactly what you’re looking for.

Functions of Motor Oil

Motor oil serves multiple important purposes in keeping a car’s engine in good condition. In addition to lubricating moving parts, motor oil:

• Transfers heat away from moving parts
• Decreases friction; effectively increasing engine power
• Inhibits oxidization
• Filters metal particles, reducing wear
• Minimizes sludge build-up

Proper motor oil maintenance can improve a used car’s performance over time. Regularly changing the oil helps the engine stay in working condition longer, and additives in the oil clean it.
