The 2018 Jeep Cherokee 2.4 oil capacity and type are crucial details for any owner looking to perform routine maintenance or simply understand their vehicle’s needs. Proper engine oil is the lifeblood of your Jeep’s 2.4L Tigershark MultiAir engine, ensuring optimal performance, longevity, and fuel efficiency. Knowing the correct specifications helps prevent potential engine damage and keeps your SUV running smoothly, whether you’re navigating city streets or heading off on an adventure.
The 2018 Jeep Cherokee, a popular compact SUV, is known for its blend of capability and comfort. The 2.4-liter Tigershark four-cylinder engine is a common powerplant for this model, offering a good balance of power and economy. However, like all modern engines, it requires precise adherence to manufacturer recommendations when it comes to lubrication.
Understanding the 2.4L Tigershark Engine
The 2.4L Tigershark MultiAir 2 engine is a naturally aspirated inline-four known for its MultiAir variable valve actuation system. This technology helps improve both fuel efficiency and power output by precisely controlling intake valve lift and timing. Due to the sophisticated nature of such engines, using the correct oil is not just a recommendation, but a necessity to ensure all components, especially those related to valve timing, operate as designed. Incorrect oil can lead to increased wear, reduced performance, and even costly repairs down the road.
Understanding the 2018 Jeep Cherokee 2.4 Oil Capacity
For the 2018 Jeep Cherokee equipped with the 2.4-liter Tigershark MultiAir 2 engine, the engine oil capacity is 5.5 US quarts (5.2 liters). This measurement includes the oil filter. It’s vital to note that when performing an oil change, you should always replace the oil filter as well. The filter plays a critical role in removing contaminants from the oil, and a new filter ensures that your fresh oil remains clean and effective for longer.
When adding oil, it’s always best to pour in slightly less than the full capacity, then check the dipstick, adding small amounts gradually until the oil level reaches the “FULL” or upper mark on the dipstick. Overfilling the engine with oil can be just as detrimental as underfilling. Too much oil can cause aeration, where the crankshaft whips the oil into a foamy consistency, reducing its lubricating properties and potentially causing seal damage. Conversely, too little oil leads to insufficient lubrication, increased friction, and accelerated wear on critical engine components.
Choosing the Right 2018 Jeep Cherokee 2.4 Oil Type
Selecting the correct oil type for your 2018 Jeep Cherokee 2.4L is paramount. The manufacturer specifies particular viscosity grades and quality standards to ensure the engine operates reliably and efficiently.
Viscosity Grade:
For the 2018 Jeep Cherokee 2.4L engine, the recommended engine oil viscosity grade is SAE 0W-20. This low-viscosity oil is designed to flow easily in cold temperatures, providing quick lubrication at start-up, while maintaining adequate protection when the engine reaches operating temperature.
API Certification:
Beyond viscosity, the oil must meet specific quality standards set by the American Petroleum Institute (API). For your 2018 Cherokee, look for oils that are API certified SN, SP, or a newer rating. These ratings indicate that the oil meets the latest industry standards for engine protection, fuel economy, and emission system compatibility. You will usually find these ratings clearly printed on the oil container’s label.
Synthetic Oil Recommendation:
While some older vehicles might still use conventional oil, modern engines like the 2.4L Tigershark are generally designed for and benefit greatly from full synthetic engine oil. Synthetic oils offer superior protection against wear, better resistance to thermal breakdown, and improved performance in extreme temperatures compared to conventional or synthetic blend oils. Although synthetic oil might have a higher upfront cost, its longer service life and enhanced protective qualities often make it a more cost-effective choice in the long run. Mopar MaxPro is the factory-fill brand, but any reputable brand meeting the specified viscosity and API standards will suffice.
Why Proper Oil Matters for Your Cherokee
Using the correct oil isn’t just about following instructions; it’s about preserving the integrity and performance of your vehicle.
Engine Longevity: Correct oil reduces friction between moving parts, minimizing wear and extending the lifespan of your engine.
Fuel Efficiency: The right viscosity oil ensures optimal engine operation, contributing to the vehicle’s advertised fuel economy.
Performance: Proper lubrication helps the engine deliver its designed power output smoothly and efficiently.
Warranty Compliance: Using oil that meets manufacturer specifications is often a condition of your vehicle’s warranty. Deviating from these recommendations could potentially void parts of your powertrain warranty.
* Emissions Control: Modern oils are formulated to be compatible with emission control systems, helping to reduce harmful pollutants.
When to Change Your Oil
Referencing your 2018 Jeep Cherokee owner’s manual is always the best practice for determining your specific oil change intervals. However, general recommendations for the 2.4L engine typically range from 10,000 miles (16,000 km) or 12 months, whichever comes first, under normal driving conditions.
If you frequently engage in “severe service” driving – which includes short trips, stop-and-go city driving, driving in dusty conditions, towing, or extreme temperatures – your oil change interval may need to be shorter, perhaps every 5,000 miles (8,000 km) or 6 months. Your vehicle’s onboard oil change indicator system is also a valuable tool that monitors driving conditions and engine usage to suggest when a service is due.
How to Check Your Oil
Regularly checking your oil level and condition is a simple yet crucial maintenance task:
1. Park on Level Ground: Ensure your Jeep is parked on a flat, level surface to get an accurate reading.
2. Warm Engine: Run the engine until it reaches operating temperature, then turn it off and wait about 5-10 minutes for the oil to drain back into the oil pan.
3. Locate Dipstick: Open the hood and find the engine oil dipstick, usually marked with a bright handle (often yellow or orange).
4. Clean Dipstick: Pull the dipstick out, wipe it clean with a rag or paper towel.
5. Reinsert and Check: Fully reinsert the dipstick, then pull it out again. Observe the oil level between the “MIN” and “MAX” (or “ADD” and “FULL”) marks.
6. Assess Condition: While checking the level, also note the oil’s color and consistency. Fresh oil is amber; very dark, gritty oil is a sign it’s time for a change.
DIY vs. Professional Service
Changing your own oil can be a rewarding and cost-saving task for the mechanically inclined. It requires basic tools, a safely supported vehicle, and proper disposal methods for used oil. However, if you’re uncomfortable working under your vehicle, or prefer the convenience and peace of mind, professional service from a certified technician is always a reliable option. They will ensure the correct oil and filter are used, and often perform a quick multi-point inspection as well.
Conclusion
Understanding the 2018 Jeep Cherokee 2.4 oil capacity and type is fundamental to maintaining your vehicle’s health and ensuring its longevity. Always use 5.5 US quarts of SAE 0W-20 full synthetic engine oil that is API certified SN, SP or higher. Adhering to these specifications and following recommended oil change intervals will keep your 2.4L Tigershark engine performing optimally, providing reliable transportation for all your adventures.
