7 Signs for Engine Health That Tell When to Change Engine Oil

A car is not just a machine but also an investment. And you would not risk your paint just because you were in a hurry to add a professional ceramic coating to your car, and you should not skip what is happening under the hood. Engine oil is the blood of your car as it allows the engine to run more friction and actually prevents the engine from melting down.

But when do you know when to change engine oil before it is too late? Here we have taken apart the warning signs that all car owners must be aware of to ensure their ride is running fast and healthy.

 

Is Your Dashboard Light Speaking to You?

The most glaring indicator when to change engine oil is the ignition of the oil pressure warning lamp. Contemporary automobiles have sensors that track the oil life or pressure. And when this light is on, it is not a demand, but a cry of pain. Besides, the Check Engine light can be associated with high rates of friction brought by old sludge-like oil.
 

Why Does Your Oil Smell Like Dark Molasses?

New engine oil is light amber in color and clear. Slowly, it accumulates microscopic rubbish, carbon, and dust from the engine, and becomes black and gritty.

Pro Tip: Raise the dipstick after every month and wipe it on a white cloth. When the oil is dark, thick, or contains particles that can be seen in it, then you require a car oil change without further notice. Moreover, the test of the dipstick will assist you in determining whether your car's engine oil level is at the necessary position; low levels of engine oil may result in disastrous engine breakdown.

 

Are You Hearing Any Knocking or Ticking?

Engine oil offers a sensitive protective film to the moving parts. When such oil wears out or is depleted, then such metal components begin to grind together. In case there is a knocking or ticking sound in the engine bay, then your oil has lost its lubricating ability. Its negligence can even lead to a replacement of the entire engine, which cannot be repaired, even by the most detailed work.
 

Is There a Smell of Burning in the Cabin?

The burning oil that smells in the air as you drive is, in itself, a big red flag. This also usually means that there is a leakage of oil or that the engine is overheating because of old oil. When the odor combines with the odor of exhaust fumes, there is a possibility that your car is dripping oil on hot engine parts. This necessitates an urgent car oil service to avoid the possibility of a fire outbreak or an engine seizure.
 

Do You See Too much Smoke from Exhaust?

Although it is only natural that some vapor will come out of your tailpipe when the weather is not hot, when the smoke looks thick, blue, or grey, it is an indication of a problem. This normally implies an oil spillage into the combustion chamber. In case you notice, it is high time to visit a professional and to find out when to change engine oil, along with checking the system.
 

Did your Fuel Economy Just Die?

With thick and dirty engine oil, the engine must exert a lot of effort in moving parts through the "sludge." This additional work consumes additional fuel. When you find yourself going to the petrol pump more frequently than usual, then it could be because you missed your engine oil changing schedule. New oil decreases the internal drag, which improves the fuel economy of your car.
 

Vibrates when Idling (Engine)?

In case of excessive internal friction in your engine, it can cause your engine to run rough. This is normally because the dirty nature of its oil causes its car to shake or shiver when you are waiting to cross the red light. It can be a professional car oil service that can oftentimes restore that idle smoothness as though it were like-new.
 

Your Vehicle Healthy 

Disregarding the indicator of used engine oil will cause irreversible damage to the engine, poor performance, and staggering costs of repairs. By understanding when to change engine oil on average every 5000 - 7500 miles (prone to varying conditions according to your manufacturer) and watching the above indicators, you will be contributing to the long life of your car. Do not wait until the engine switches off. Test your dipstick now, look up the amount of engine oil recommended in the owner's manual for your car engine, and book your next oil change appointment at a reputable service station.
 

What is so Important About the Consistency of Oil?

Engine oil is developed to possess a specified amount of viscosity(thickness). With fresh oil, the viscosity decreases with low temperature but increases with high temperature.

The Issue: With time, the oil is subjected to the heat of the combustion process, and as a result, its molecular structure is degraded in this process known as thermal degradation.

The Product: The oil is converted into sludge. Instead of lubricating, it starts to operate like sticky glue, thus making it more challenging to get the engine started. This is where the oil used by the engine ought to be replaced so that there will be no contamination of metals.


Checking the Amount of My Car Engine Oil Capacity?

Each vehicle contains a maximum capacity of car engine oil, which is normally expressed in liters or quarts. This is a crucial thing to know since overfilling is as dangerous as underfilling.

Overfilling: This may result in foaming, whereby the oil becomes a frothy, air-bubbled liquid, which is incapable of lubricating the engine.

Underfilling: Underfilling will cause the rest of the oil to overheat quickly, resulting in the need to change the entire engine oil right away than what was anticipated.

Location: Look in your owner's manual or underneath your hood. The average size of a modern sedan takes 4-6 liters.

 

What Goes on When We Have a Professional Oil Service Done on Your Car?

It is not only a matter of pouring in a fresh liquid to clean up the car oil. Here are certain crucial steps involved in the process that can be summarized as follows:

The Drain: The draining of old oil is performed when the engine is hot so that the engine will empty all the contaminants.

Filter Replacement: This filter through metal shavings. Every engine oil must be accompanied by a new filter replacement.

Inspection: looking at the oil pan gasket and drain plug leakages.

The Refill: Fill your grade (i.e., 5W-30 or 0W-20), which is needed to fit into your particular type of engine.

 

Knowing the Time vs. Dilemma

People drive a lot, and they ask, I have not driven much, and therefore, I do not need an update regarding engine oil change.

The Answer is Yes. Oil is degraded even in the garage where the car is parked. This could lead to the accumulation of moisture in the oil pan (condensation), and this is what leads to the formation of acids.

Rule of Thumb: The number of miles (e.g., 10,000 kilometers) does not count, but you have to know when to change engine oil, and that should be done at least once every 6-12 months, to ensure your engine has not been ruined.

 

How to Take Control of the Life of Your Car

It produces heat up to 180 °C within your engine due to metal friction. Lack of oil, such as pistons and camshafts, will cause them to warp or break.

Remedy: Have a set routine for changing your engine oil depending on how you drive (highway driving will not demand frequent engine oil change than city driving).

Action: Spend 5 minutes today and check the level of oil and color. In case it appears dark brown like coffee or it is below the Min line in the dipstick, book a service at once.

A clean engine should have a clean exterior. When you are preoccupied with the health of the mechanics in your automobile, remember the fact that your paint is being assaulted daily by environmental pollutants. Being a professional car enthusiast, I know that it is necessary for the modern reader to know that sometimes less is more. 

 

What is the Relationship Between Your Driving Style and Oil Change Interval?

Not every kilometer is the same thing. When you are often caught in a traffic jam or do short trips that are less than 5 kilometers, then your engine is working under severe conditions. When that happens, the engine does not spend time long enough time to evaporate the water vapor that accumulates in the crankcase.

The Chemical Effect: This water is combined with sulfur (a fuel-burning product) to form sulfuric acid. Unless you get into the habit of changing your engine oil regularly, these acids will start corroding the inner seals and bearings of your engine.

The Solution: To the urban drivers, it is a far safer option to make a car oil service every 5,000-7,000 km rather than waiting until reaching the maximum limit of 15,000 km by the manufacturer.

 

Is Fresh Oil Really Cheap at the Petrol Pump?

The most ignored advantage is knowing the time to change your engine oil, and it can affect your wallet at your fuel station. The internal workings of the engine, such as the pistons and the crankshaft, experience a lot more resistance as the oil ages and forms sludge.

Internal Friction: Imagine swimming through water as compared to swimming through honey. To get over this internal drag, your engine consumes some of your fuel.

The Efficiency Boost: You will be able to get your engine rotating more freely by keeping the right amount of fresh, low-friction synthetic oil in the car engine. This can increase your fuel economy by up to 2-5 percent, essentially justifying the cost of changing the oil after a few months of driving.

 

Does Service History Advantage Your Resale Value?

We are aware at The Detailing Mafia that a car that appears to be in its new state should also perform like in its new state. The only thing that a potential buyer or a professional buyer will examine when you come to sell your car would be the state of the paint used and the regularity of the car's oil services.

The Paper trail: A written record of all the engine oil changes is evidence that the car is maintained at a level of excellence. It indicates to the customer that the engine does not have any internal sludge and carbon deposits.

The Outcome: A vehicle whose maintenance history is checked and that has a clean and paint protection film or ceramic-coated finish can fetch a 15-20 percent higher resale price as compared to a counterpart that has not been maintained. It is not only maintenance, but it is an investment approach.

 

What Do Oil Health and Turbochargers Have in Common with Each Other?

In the event that your car has a turbocharger (as fitted to most modern petrol and diesel cars), then the quality of your oil is even more vital. The speed of turbochargers is more than 200,000 RPM, and they are cooled with the same oil used to lubricate your engine.

The Hazard: The dirty oil has the potential of blocking the small oil feed lines to the turbo. Even a few seconds without oil to the turbo will make the bearings fail, and the cost of repairing the bearings will be lakhs.

Pro-Tip: You should use the best grade of synthetic oil that you can fit your car engine oil capacity to be sure that the turbo remains cool and lubricated when under pressure.

 

Take Control of Your Vehicle's Life Span

Here are the ways you can maintain your automobile's health.

Issue: Friction of metals develops heat up to 180° C within your engine. In the absence of proper oil, such parts as pistons, camshafts, and turbochargers will get out of shape, crack, and even seize.

Solution: You should have a strict schedule by which you should change your vehicle's engine oil depending on your surroundings. Hot and dusty places require more frequent treatment.

Action: Spend a few minutes today (5 minutes) and check your color and oil level. When it appears like dark coffee or below the Min line of the dipstick, then immediately book a car oil service.
