Signs My Car’s Oil Needs Changing

No Comments

The oil changing schedule for conventional oil is every 3,000 miles. The changing schedule for synthetic oil is every 5,000 miles. If you cannot remember the last time that you have the oil changed in your car, it is most likely due for an oil change. Here are signs that it is.

Knocking Sounds

If you hear knocking sounds coming from the engine, it’s possible that the oil is no longer lubricating the moving parts. Consequently, if you continue to operate your vehicle when the engine is in this condition, you can damage it irreparably. Bring your vehicle to our shop for an oil change right away.

Dark Brown Oil

If you look at your motor oil and it is dark brown, it needs to be changed. Motor oil should always be light brown. Motor oil that is dark in color has lost its viscosity, is oxidizing, and is dirty. Unfortunately, when this oil circulates through the engine, it can damage it.

Low Oil Level

If the oil level is too low in your engine, this, too, is a sign that the oil needs to be changed. Bring your vehicle to our shop right away so we can drain the dirty oil and check for oil leaks. If everything is okay, we will replace the dirty oil with new motor oil and also replace the oil filter.

Oil Warning Light

Your vehicle may tell you that is overdue for an oil change. If the oil light comes on and remains on, you need to change the motor oil. This warning light will also turn on if the oil level is too low or you have reduced oil pressure in the engine. Pay attention to this warning light.

Exhaust Smoke

When the oil gets old, it also gets dirty. Consequently, it deposits sludge throughout the engine that is burned away when the engine is in operation. This can create excess exhaust smoke that flows out of the tailpipe. In some cases, the smoke may be blue if the oil is leaking.


Finally, your vehicle may vibrate when you are sitting at an idle because the engine is not running smoothly. The engine needs motor oil to lubricate the moving parts and keep its operations smooth. If the oil needs to be changed, the engine will run inefficiently and roughly.
