What Are the Signs That You Need an Oil Change?

Oct 12, 2018

Oil is the lifeblood of your engine and can break down over time. It lubricates the components of your engine to fight friction and the buildup of heat. Oil changes keep your engine working in optimal condition for many years to come.

But when do you need to schedule one? There are a variety of signs that you need an oil change. Read on to learn about these signs and why it’s important to perform regular maintenance.

Is It Time for an Oil Change?

The following signs are indications that it’s time for an oil change:

Indicator light

A check engine light or message displayed on the dash is an easy way to know it’s time. Most of today’s vehicles have a counter built into their systems to show the indicator at the manufacturer’s recommended mileage. You can also look in your owner’s manual for your manufacturer’s recommended oil change schedule if you want to be certain you’re sticking to the suggested time frame.

Loud noises

While it’s designed to fight heat and friction, oil wears down over time and with more miles. When it wears down, the oil loses its lubrication, which can cause engine parts to start grinding, knocking, or rattling.

Low oil levels

Locate the dipstick, and pull it all the way out. Wipe off any oil from it, insert it all the way back into the engine, and pull it back out. This will give a proper measurement of the oil in the car. If the oil is below the minimum mark on the dipstick, you need to add oil to the engine.

Color

A light color indicates the oil is fresh and still has life in it. If the color is brown or black, the oil is old or used and may need to be changed. If you notice the oil has a milky color, this could be a sign that coolant has leaked into the engine.

Particulates

When checking the engine, if you notice metal particles in the oil, it can indicate that you have internal engine damage. If you see the milky color or metal particles, get your vehicle to a service center for further diagnosis.
