As a Jeep owner, you want to ensure your vehicle is always in top condition. This includes regular maintenance, such as oil changes, to ensure your Jeep runs smoothly and efficiently. However, when the ‘Oil Change Required’ message appears on your dashboard, it can be confusing and even concerning.
When Your Jeep Says ‘Oil Change Required,’ it means it is time to change the oil. This software-controlled indicator will flash for about ten seconds on the EVIC display. While the recommended oil change intervals may vary from vehicle to vehicle, the indicator system is duty cycle-based.
In this article, I will delve into the meaning behind this message and provide you with the information you need to take appropriate action. So, keep reading to find out more.
Working Principle of the Jeep’s ‘Oil Change Required’ Indicator System:
Jeep’s ‘Oil Change Required’ indicator system is solely software-based and does not incorporate an oil quality sensor.
The indicator system uses a duty cycle-based algorithm to determine when an oil change is due, which means that the interval between oil changes may vary based on the driving habits of the vehicle operator.
The software algorithm monitors various factors, such as mileage and engine operating conditions, to determine when an oil change is necessary.
Therefore, the ‘Oil Change Required’ message may be triggered sooner or later than the recommended oil change interval, depending on how the vehicle is driven.
It is important to note that the software-based indicator system is not affected by the quality of the oil used in the engine.
Therefore, it is recommended to use the manufacturer’s recommended oil and follow the recommended oil change intervals to maintain the engine’s proper functioning and avoid any potential damage.

Understanding Jeep ‘Oil Change Required’ Message:
A Jeep's 'Oil Change Required' message indicates it's time to change the engine oil. The oil in a car's engine lubricates and protects its moving parts. However, it can become contaminated with dirt and debris over time, affecting the engine's performance and longevity.
Jeeps have a maintenance reminder system that monitors various factors, including mileage and driving conditions, to determine when an oil change is needed.
When the system determines that an oil change is due, it will display the ‘Oil Change Required’ message on the vehicle’s dashboard.
It’s essential to follow the recommended oil change schedule in the owner’s manual to ensure that the engine is maintained correctly and to avoid any potential damage to the vehicle.
Failure to change the oil at the recommended intervals can lead to engine problems and costly repairs.
Factors Responsible for the ‘Oil Change Required’ Message in Jeep:
Here, I’ll explore the most common factors responsible for Jeeps’s “oil change required” message. These factors include:
- Lower levels of oil
- Damage to the coolant hose
- Oil leakage in the vehicle
- Cracking of oil pan in vehicle
1. Lower Levels of Oil:
A low engine oil level in a Jeep most commonly triggers the ‘Oil Change Required’ message.
In such a case, it is imperative to check the oil level and ensure it is at least halfway up on the dipstick before resuming driving.
The engine probably has insufficient oil if there are no indications of oil leakage. This can happen for multiple reasons, including oil leaks, consumption, or burning oil.
It is critical to comprehend that the Jeep engine necessitates a specific amount of oil to function efficiently. Inadequate oil levels force the engine to work harder, escalating friction and heat accumulation.
Consequently, engine components can get damaged, leading to expensive repairs or, in some cases, engine failure.
2. Damage to Coolant Hose:
The coolant hose is an essential component of this system, as it carries the coolant fluid to the engine and back to the radiator.
However, the coolant hose can get damaged due to extreme weather conditions. If you live in an area with hot or cold weather, the coolant hose in your Jeep might be at risk of damage.
If the coolant hose is damaged, the engine can overheat, leading to premature wear and tear of the engine oil.
In addition, the engine oil can become contaminated with dirt and debris, leading to decreased engine performance, which triggers the ‘Oil Change Required’ message.
3. Oil Leakage in Vehicle:
If you observe oil leakage from any engine block of your Jeep, you may receive the ‘Oil Change Required’ message.
Oil leakage in the vehicle can damage the engine, so fixing this problem as soon as possible is better. If there is oil leakage under the transmission pan of the vehicle, it is a severe matter of concern, so it is better to replace these parts with new ones.
4. Cracking of Oil Pan in Jeep:
The presence of a cracked engine block or head coverings in your Jeep would also lead to the flashing of the ‘Oil Change Required’ message on the dashboard of your vehicle.
The head covering and oil pan cracking during their manufacturing assembly can lead to this issue. The issue can be due to the following:
- Assembling of the engine or its transfer case
- Assembling or manufacturing of brake, steering system, or suspension
- Assembling of steering or axle components
- Assembling of the power steering pump
Symptoms Indicating the Necessity of Oil Change in Jeep:
The presence of new oil in the vehicle helps lubricate the vehicle’s moving components. So, it is better to keep the oil clean for better working of the engine. Dirty or old oil is not able to quickly cool the engine.
Here, I list down the most common symptoms which indicate that the oil needs to be changed now:
Presence of dirty oil
Production of knocking sound in engine
Checking the engine light
Production of smoke from exhaust
Resetting the Oil Change Message in Jeep:
There is an engine indicator system in Jeeps which is a software-based system. It accounts for the mileage and other factors affecting the oil's quality. The message for the oil change required is known to flash for about 5-10 seconds on the EVIC display and indicates the oil changing interval.
As I mentioned before, this indicator system is duty-cycle based and depends on the owner’s driving style.
Here I will explain the steps to reset the message in your Jeep.
- STEP 1: Turn your ignition to the “On” position (do not start the engine).
- STEP 2: Press the gas pedal all the way down to the floor three times within 10 seconds.
- STEP 3: Turn the key to the “Off” position.
- STEP 4: Now, take out the key from the ignition.
- STEP 5: Wait a few seconds, then reinsert the key into the ignition and turn it to the “On” position.
- STEP 6: If the “Oil Change Required” message is still displayed, repeat steps 2-5.
- STEP 7: Turn the key to the “Off” position once the message disappears.
Congratulations, you have successfully reset your Jeep’s “Oil Change Required” message!
Recommended Oils for Jeeps:
Remember a few things before changing the oil in your Jeep.
Your Jeep will not work properly on regular engine oil, so that you will need the specific oil for Jeeps.
There are 3 types of oils recommended for your Jeep:
Here, I lay down the recommended oil chart for specific Jeep types:
Jeep Grand Cherokee
Changing the Oil Filter:
It is often related that changing the oil filter along with the oil is an excellent thing to do side-by-side. Most Jeep owners say that it is necessary to change the oil filter when you change the oil of your vehicle to avoid the ‘Oil Change Required’ message.
But some people disagree with this. Actuality, it all depends on the type of the vehicle.
If there is an oil filter in your vehicle that can be changed without removing an engine, it is not necessary to change it when you change the oil.
But, if the oil filter is at a location that is not easily accessible, removing it whenever you replace the oil is recommended.
It is a good idea to change the oil filter in the case:
- You have replaced the oil in your vehicle recently.
- Your vehicle’s engine has been running for a long time without any service.
- There is a high mileage of your Jeep.
- The maximum mileage recommended for your Jeep for changing the oil filter is 3000-5000 miles.
- Changing the oil filter in the Jeep
- Fill up a bucket of 5-gallon quantity with the coolant.
- Remove the cap from the drain plug, which is located inside the vehicle’s engine block.
- Dirty coolant will leak away from the vehicle, so place a catch pan under the vehicle so that water cannot get into the engine.
- Lift and remove the black plastic cover from your oil filter housing. You can use a wrench to loosen it.
- Replace the old oil filter with a new one and install it.
Keeping up with regular oil changes is a crucial aspect of maintaining your Jeep and ensuring it runs smoothly. The oil change required indicator is a helpful reminder to take care of this task, and resetting it is a simple process.
By following the manufacturer’s guidance and addressing any issues promptly, you can keep your Jeep in top condition for years to come.
Remember to prioritize regular maintenance, and your Jeep will continue to serve you well on all your adventures.
