Data verified by Nick Marchenko, PhD
Maintaining the engine oil in your 2020–2022 Jeep Gladiator is crucial for optimal performance and longevity. This versatile truck offers two engine options: the ERC 3.6L V6 petrol engine, which requires 5 quarts of 0W-20 oil, and the EXJ 3.0L V-6 diesel engine, which has a larger oil capacity of 9 quarts with a viscosity of 5W-40. Regular oil changes help ensure that your engine runs smoothly and efficiently, while also protecting it from wear and tear.
In addition to oil maintenance, it's important to monitor coolant levels. The ERC engine has a coolant capacity of 13 quarts, while the EXJ engine holds 12 quarts. Keeping both oil and coolant at the recommended levels will help maintain the performance of your Jeep Gladiator, whether you're tackling off-road adventures or daily commutes.

How often should I change oil in a Jeep Gladiator?
It's generally recommended to change the oil in your Jeep Gladiator every 6,000 to 7,500 miles, depending on driving conditions and oil type. Always refer to your owner's manual for specific guidelines.
What is the coolant capacity of the Jeep Gladiator?
The coolant capacity for the Jeep Gladiator differs by engine. The ERC 3.6L V6 petrol engine has a coolant capacity of 13 quarts, while the EXJ 3.0L V-6 diesel engine holds 12 quarts.
Does the Jeep Gladiator need synthetic oil?
While synthetic oil is not mandatory for the Jeep Gladiator, it is highly recommended for both engine options. Synthetic oil provides better protection and performance, especially in extreme temperatures.
What happens if I use the wrong oil viscosity in my Jeep Gladiator?
Using the wrong oil viscosity can lead to inadequate lubrication, increased engine wear, and potential overheating. It's crucial to use the recommended viscosity for your specific engine to ensure optimal performance.
What is an oil life monitor and how does it work?
An oil life monitor is a system that calculates the remaining life of your engine oil based on driving conditions and habits. It helps you determine when it's time for an oil change, ensuring you maintain proper engine health.
Can I mix synthetic and conventional oil?
While it's technically possible to mix synthetic and conventional oil, it is not recommended. Mixing can reduce the effectiveness of the oil and may lead to decreased engine protection.
How do I know if my Jeep Gladiator has an oil leak?
Signs of an oil leak in your Jeep Gladiator include oil spots on the ground where you park, a drop in oil levels, or an oily residue around the engine. Regularly checking your oil level can help identify leaks early.
What causes excessive oil consumption?
Excessive oil consumption can be caused by worn engine components, such as piston rings or valve seals, which allow oil to escape into the combustion chamber. Regular maintenance can help identify and mitigate these issues.
Should I check my oil when the engine is hot or cold?
It's best to check your oil when the engine is warm, but not hot. This allows the oil to circulate and provide a more accurate reading on the dipstick.
What is the difference between an oil change and a flush?
An oil change involves draining the old oil and replacing it with new oil, while an oil flush is a process that cleans the engine's internal components by removing sludge and contaminants. Flushing is generally not necessary for regular maintenance.
