Accurate Reading of Engine Oil Level: How to Avoid Common Problems of Rapid Oil Loss?

In the era of modern cars equipped with advanced diagnostic systems, the skill of checking your oil level manually with a rag and a dipstick might seem simple or outdated. However, this manual inspection remains one of the most important ways to get direct information about your engine’s condition and can alert you early before any complex digital warnings appear.

In this article, we guide you step-by-step on the correct way to check your engine oil level using a dipstick, and explain in detail the three main reasons oil might be dropping quickly. Additionally, we share tips on how to keep your engine in top condition.

Why Is Checking the Oil Level So Important?

Oil is an essential element in the operation of the engine. Its functions include:

• Lubricating metallic parts and reducing friction between rapidly moving engine components.
  
  

• Cleaning the engine from dirt and deposits that may impair its parts.
  
  

• Protecting the engine from wear and corrosion.
  
  

• Cooling the engine partially by dissipating heat.
  
  

This means having a sufficient amount of quality oil ensures your engine runs efficiently and prolongs its lifespan. Regular oil level checks give you the opportunity to ensure the engine is not at risk.

Before You Begin: When and Where Should You Check the Oil Level?

1. Best Timing

It is best to check the oil level when the engine is warm but not too hot. Start the car for a few minutes, then turn it off and wait a couple of minutes to let the engine calm down. This helps the oil distribute evenly inside the engine and provides an accurate reading.

2. Proper Surface

Make sure the car is parked on a level surface because parking on a slope could give an incorrect reading and lead to adding the wrong oil amount.

How to Accurately Read the Dipstick

1. Open the hood and locate the dipstick, usually a brightly colored (yellow or orange) handle for easy finding.
   
   

2. Pull out the dipstick slowly and wipe the end clean with a clean cloth to remove any oil stuck on it.
   
   

3. Reinsert the dipstick fully, then pull it out again to read the oil level.
   
   

4. Look for the measuring marks on the dipstick: they typically have two marks or dots indicating the minimum and maximum acceptable oil levels.
   
   

5. Ensure the oil level is between the two marks. If it is near or below the minimum mark, you should add the recommended type of oil.
   
   

What Does Healthy Oil Look Like?

The level matters, but the oil’s color and texture also reflect its condition:

• Healthy oil: Usually amber-colored, transparent or light brown with a smooth texture.
  
  

• Dirty or degraded oil: Appears dark, contains dirt particles, or looks creamy or watery—signs of contamination from water or other elements, meaning it needs immediate replacement.
  
  

Three Main Reasons Oil Level Drops Quickly

Reason One: Normal Oil Consumption

Some vehicles, especially older ones or those with high mileage, consume a certain amount of oil as part of normal engine operation. Manufacturers often specify an acceptable consumption amount in the owner’s manual. If the consumption is within these limits, consistent topping up is sufficient.

Reason Two: Oil Leaks

Oil leaks from the engine or lubrication system components are common and not always obvious. Check for:

• Oil spots under the car where it’s usually parked.
  
  

• Seals, gaskets, oil filter, and oil lines for signs of leakage.
  
  

• Warning lights on your dashboard related to oil pressure or level during routine servicing.
  
  

Leaks require prompt repair to avoid excessive oil loss and potential engine damage.

Reason Three: Worn Piston Rings or Engine Valves

If piston rings or engine valves wear out, oil may seep into the combustion chamber and burn with the fuel. This causes a notable drop in oil level, along with blue smoke from the exhaust and an oily burnt smell.

This issue demands a thorough mechanical inspection and probably specialized repairs.

What Should You Do if the Oil Level Is Low?

• Add the correct oil type following the manufacturer’s recommendations found in your car’s manual.
  
  

• Avoid overfilling, as excess oil can cause increased pressure and damage engine parts.
  
  

• If the oil level drops quickly again despite adding oil, do not ignore it and visit a qualified service center.
  
  

Tips for Maintaining a Healthy Oil Level

• Check the oil regularly, at least once a month.
  
  

• Change the oil according to the schedule recommended in your owner’s manual.
  
  

• Use quality oils that meet the engine specifications.
  
  

• Always monitor the oil’s color and smell.
  
  

• Pay attention to any dashboard warnings related to oil level or pressure.
  
  

The Importance of a Good Relationship Between the Driver and the Engine

Maintaining these habits and adopting the practice of checking your oil level builds trust between you and your car, giving you greater control over your vehicle’s safety and peace of mind. It also saves you costly repairs over the long term.
