What Does Engine Oil Do?

There are a few different reasons your car may be leaking oil. If you haven't gotten an oil change in a while, this may be a contributing factor. The engine oil in your car serves many purposes. It lubricates all the components of your engine, which helps reduce friction and heat.

In turn, this protects the parts and helps extend their life by preventing wear and tear. Over time, the oil collects debris and builds up with sludge that keeps from reaching the engine. At this point, the oil needs to be replaced, so it can continue lubricating and protecting the engine.

Reasons Your Car May Be Leaking Fluid

Although old and dirty oil may contribute to a leak, there are a few other reasons your car might be leaking oil, such as:

  • Damaged oil pan
  • Damaged oil filter or drain plug
  • Damaged or improperly installed gaskets

The only way to know what is causing your car to leak oil is by taking it to a trusted service technician. That way, they can quickly diagnose the root cause and begin fixing it.

Other Types of Fluid Leaks in Your Car

To be sure your vehicle is leaking engine oil and not another type of fluid, check the color. If it's brown or black in color, it is most likely engine oil. However, if it is pink or red and has a sweet smell, it is transmission oil.

On the other hand, if it is clear, it may be water leaking from your AC unit. It may also be antifreeze, which comes in several different colors, including blue, red, yellow, orange, or green.

Tips for Preventing Your Car From Leaking Oil

The best way to extend the life of your car and protect your automotive investment is by following the maintenance schedule in your owner's manual. This outlines key service and mileage intervals for you to follow, including oil and filter changes, brake pad replacements, and more.

By having your car serviced regularly, you can quickly address anything that may arise.
