Should I Check the Engine Oil while the Engine is Hot or Cold?

Typically, the best way to check your oil depends on your car. For most cars, checking engine oil with a cold engine is recommended.

This is because, a cold engine allows the oil in the oil pan to settle, resulting in more accurate readings.

However, some newer cars have electronic oil level controllers that require the engine to be warm for proper measurement.

In that case, you should wait for at least 15 minutes after the engine was last run before checking the oil.

You should also be careful not to burn yourself with the hot oil.

To find out what your car needs, look at your Owner’s Manual.

If you don’t have the paper version, you can probably find the digital one online with some searching.

The best time to check your oil depends on the kind of oil you use and the ambient temperature at your location.

Usually, the information on some of these factors can be available on your owner’s manual.

Importance of checking your engine oil

Checking your engine oil regularly is important for the health and performance of your car.

It helps prevent engine damage, reduce emissions, and improve fuel economy.

Additionally, you should check your oil at least once a month or more often if you drive a lot or in harsh conditions.

You should also change your oil and oil filter according to the manufacturer’s recommendations, which may vary depending on the type of oil you use and the driving conditions you encounter.

How often should I check my oil?

How frequently you check your engine oil depends on various factors.

Some of these factors include:

  • the model/make of your vehicle,
  • driving conditions, and
  • oil quality.

However, the general rule of thumb is to check your oil level at least once a month or every 1,000 miles, whichever comes sooner.

Importantly, you should also check your oil before a long trip.

Typically, regularly checking your oil levels can help you prevent engine damage, reduce emissions, and improve fuel economy.

How to check the level of Engine Oil

To check your engine oil level, you will need a clean cloth or paper towel and a dipstick, which is usually located near the front of the engine.

Here are the steps to follow:

  • Park your car on a level surface and turn off the engine.
  • Open the hood and locate the dipstick. It may have a yellow or orange handle with an oil can symbol on it.
  • Pull out the dipstick and wipe it clean with the cloth or paper towel.
  • Insert the dipstick back into the tube and push it all the way in.
  • Pull out the dipstick again and look at the oil level. It should be between the two marks or holes on the dipstick. If the oil level is below the lower mark, you need to add more oil. If the oil level is above the upper mark, you have too much oil and need to drain some.
  • If you need to add or drain oil, make sure you use the correct type and viscosity for your car. You can find this information in your owner’s manual or on the oil filler cap.
  • After adjusting the oil level, check it again with the dipstick to make sure it is correct.
  • Put the dipstick back into the tube and close the hood.

How to monitor engine oil level

In most cars, the oil level is monitored by a dipstick; which is a tool that lets you check the oil level.

It is a thin metal stick that goes into the oil pan.

Typically, a dipstick has a yellow handle or a metal loop on the top.

You can find it on the top of the engine. If you can’t see it, look at your owner’s manual to locate it.

Furthermore, the dipstick has two marks or lines on the bottom.

The top mark means the oil pan is full and the bottom mark means the oil pan needs more oil.

The bottom mark is usually the point where you need to add one quart of oil to fill the pan.


Checking your engine oil is one of the simplest and most important things you can do to keep your car running smoothly.

Nevertheless, it’s not as simple as just pulling out the dipstick and looking at the oil level.

You also need to consider the temperature of the engine, the type of oil, and the weather conditions.

By following the guidelines in this article, you can learn how to check your oil correctly and avoid common mistakes that can damage your engine.

Always remember to check your owner’s manual for the specific recommendations for your car, and to check your oil regularly or before a long trip.

By doing so, you can ensure your engine’s health and longevity, and save money on repairs and fuel.
