What are the main overdue oil change symptoms? Every car’s engine oil is like its lifeblood. Oil is required by the engine to lubricate its moving parts and keep them running smoothly. In actuality, oil is necessary for the operation of all engines. It makes no difference if you’re using a lawnmower, generator, or even a motorbike. If it has an engine, the oil must be used to lubricate it.

The components in an engine are always moving and rubbing against one another. Due to the continual friction, heat is produced. These moving elements require oil to flow through them in order for the oil to absorb heat and prevent overheating.

A well-maintained oil completes its purpose. In need of replacement is old oil. Fortunately, signs of an impending oil change are simple to identify. let’s explore with Teslasuggest

The 10 Overdue Oil Change Symptoms

The 10 Overdue Oil Change Symptoms

There are several overdue oil change symptoms that might appear and suggest that your automobile needs an oil change and perhaps a tune-up (for more information on what a tune-up entails, see below).

When you bring your car in for an oil change, the mechanic will change the oil and oil filter, check for leaks and other obvious problems, and then offer you additional advice on what they believe needs to be done.

They might not always find every problem, so you shouldn’t always rely on them to do this correctly. This is why you need to be aware of the symptoms that point to the necessity for some form of tune-up.

The top 10 overdue oil change symptoms are listed below.

Dark or Dirty Oil

If you have never seen pristine, brand-new engine oil before, it resembles bright amber. However, when oil ages and becomes soiled owing to the accumulation of residual particles in the engine, it takes on a considerably deeper, nearly black hue.

You should get into the habit of regularly checking the state of your oil. Simply take out your oil dipstick and inspect the oil’s color. You may also use a paper towel to clean the end of the dipstick to acquire a more precise reading. Your oil has to be changed if it is dark brown or black.

Noises of Ticking or Tapping

This is one of the overdue oil change symptoms. After some time, engine oil becomes stale and worn. Because of this, automakers advise oil changes every 5,000 miles or so. If your car has old oil, it’s probably growing thicker and dirtier.

This will hinder the oil’s ability to adequately lubricate the parts of your engine. Your engine will therefore start to emit a variety of metal-on-metal sounds as a result of the improper lubrication. If you neglect the problem, major engine damage may occur; therefore, get an oil change straight away.

Burned-Oil Aroma

Your car’s interior cabin may begin to smell like burned oil, which indicates an issue with your oil. It often denotes an oil leak that is dripping oil onto hot engine components.

It also suggests that your engine is probably running short on oil, which is making it overheat. Fix the oil leak as soon as possible and add new oil.

Poor Fuel Economy

You may need an oil change if you notice your gas mileage has decreased from what it once was. If engine oil isn’t changed as it ages, it will eventually become a thick, almost sludge-like consistency. The moving parts of your engine experience more resistance from thick oil, which makes it work harder and consume more gasoline.

Other factors might contribute to poor gas economy, but a quick oil change will assist if your oil is black and considerably thicker than fresh oil.

Exhaust Smoke

This is one of the main overdue oil change symptoms. If you reside in a chilly climate, you are accustomed to seeing vapor coming from your car’s tailpipe. However, you may have an oil leak if you really start to notice blue or gray smoke coming from your exhaust.

This is accompanied by a burned oil odor, and the smoke is a result of your engine not having enough oil to lubricate all of its moving components owing to the leak. Therefore, get the oil replenished and the oil leak rectified.

Car Stalling

What are the overdue oil change symptoms? You may have a little problem or a larger one if your car stalls while you’re driving. A minor issue would be if your spark plugs were damaged or your fuel filter was blocked. A little tune-up may replace anything like this. Something like a damaged fuel pump or blocked catalytic converter that has to be replaced would be a bigger issue.


Your engine won’t perform as well at lubricating its parts if there isn’t enough oil in it or if it hasn’t been changed in a while. The engine will ultimately overheat as a result of this increased heating. Changing your oil and replacing it with new oil can frequently solve the issue.

Warning Lights

Modern automobiles may more easily identify a problem early on before it worsens thanks to their processors and sensors. Consult your owner’s handbook to learn what an indicator light on your dashboard indicates if you see it on.

Based on the number of miles you’ve traveled since your last oil change, a “Service Engine Soon” light indicates that you should get an oil change. Other warning lights will alert you to a variety of issues, including a low battery, a burned-out tail light, a malfunctioning gearbox, and more.

Some more recent cars even monitor your oil condition (through sensors or a predetermined interval) and alert you when it needs to be changed. In some cases, the check engine light will illuminate, necessitating the use of an OBD2 scanner or the assistance of a professional to look for the exact problem.

Engine Starting Issues

You may need to examine the connections on top of your battery for corrosion and clean them with a wire brush if you find that your engine constantly struggles to start. It could be time to replace your battery if it has been in use for at least a few years.

The dashboard lights may start to fade as the engine hesitates before starting. You obviously need a tune-up, which can require cleaning the battery posts and terminals or perhaps getting a new battery.

Changing Uncertainty

If your automobile is automatic, you shouldn’t experience any issues when it changes gears. However, if there is lag or reluctance when you shift gears, it can indicate that your gearbox needs fresh oil or filters. Of course, it might also indicate a more serious issue. Because of this, having your automobile tuned up will at least identify the issue.


These are the main overdue oil change symptoms. Your vehicle’s engine deserves care and attention. Neglecting oil changes can lead to a host of problems, from poor performance to engine failure. By staying vigilant and following a routine maintenance schedule, you can ensure that your vehicle runs smoothly and efficiently for years to come.
