Good vehicle maintenance includes regular oil changes. However, some signs mean you need fresh oil before the mileage indicator says it's time. When you observe any of these conditions, don't delay in taking your car to a trusted service station for new motor oil.   

How to Tell It's Time for an Oil Change

1. Visible Tailpipe Exhaust

Generally, cars don't have exhaust smoke coming from their tailpipes. If you see a trail of smoke in the rearview mirror and it's coming from your car, it means the motor oil is old, not working as it should, and needs changing. 

This sign may indicate other problems, such as a cracked gasket or damaged piston rings, so consider getting an auto diagnostic and computer analysis for peace of mind.

2. Noisy Engine

Engines need motor oil to lubricate the moving parts. Old, worn-out, or poor quality oil doesn't do the job. 

If you hear knocking or ticking in the engine while driving, it's wise to have the oil changed and the engine checked for damage from lack of lubrication.

3. Dirty or Dark Oil

Clean motor oil has a partially translucent, golden color. As it circulates through your engine, the oil gathers particles of dirt which make it look darker. Get into the habit of checking your engine oil monthly or more often if you have an older car or drive long distances frequently. 

Take out the dipstick, wipe it off with a clean rag or paper towel, place it back in the oil tank, and remove it again. If the oil is so dark you can't see the dipstick through it, it's time for an oil change.
