Why Your 2018 Jeep Renegade Oil Change is Crucial for Trail & Town
Engine oil is the lifeblood of your Renegade. It lubricates moving parts, reduces friction, cools the engine, and cleans away harmful deposits. Over time, this oil breaks down, losing its viscosity and ability to protect.
Regular maintenance, particularly a timely oil change, prevents costly engine damage. It ensures peak performance, better fuel economy, and extends the overall lifespan of your vehicle. For off-roaders, this is even more critical; dirty oil can’t handle the extra stress of challenging terrain.
Understanding Your Renegade’s Engine Needs
The 2018 Jeep Renegade typically comes with one of two engine options: the 1.4L MultiAir Turbo or the 2.4L Tigershark MultiAir 2. Both engines have specific oil requirements that you absolutely must adhere to.
Using the wrong type or viscosity of oil can lead to premature wear, reduced efficiency, and potentially serious engine problems. Always check your owner’s manual for the definitive specification, but we’ll provide common recommendations here.
Choosing the Right Engine Oil
For most 2018 Jeep Renegade models, synthetic oil is the recommended choice. Synthetic oils offer superior protection, better performance in extreme temperatures, and a longer service life compared to conventional oils.
- 1.4L MultiAir Turbo: Typically requires 5W-40 full synthetic oil, meeting Chrysler MS-12991 or API SN/SM standards.
- 2.4L Tigershark MultiAir 2: Usually calls for 0W-20 full synthetic oil, meeting Chrysler MS-6395 or API SN/SM standards.
Always verify these specifications with your owner’s manual. Look for the API “starburst” symbol on the oil container, which indicates it meets current engine protection standards.
Selecting the Correct Oil Filter
Don’t skimp on the oil filter. A high-quality oil filter is just as important as the oil itself. It traps contaminants, preventing them from recirculating through your engine.
We recommend using an OEM (Original Equipment Manufacturer) Mopar filter or a reputable aftermarket brand like Wix, Mann-Filter, or Fram (specifically their premium lines). Ensure the filter is designed for your specific Renegade engine.

Pre-Flight Check: Safely Preparing Your Renegade for the Oil Change
Safety should always be your top priority. Hot oil can cause severe burns, and a falling vehicle can be fatal. Take your time with these preparatory steps.
Warm Up the Engine (Slightly)
Drive your Renegade for 5-10 minutes to bring the oil to a warm, but not scalding hot, temperature. Warm oil flows more easily, allowing for a more complete drain. Just be careful; it will still be hot.
Parking and Securing Your Vehicle
Park your Renegade on a level, hard surface. Engage the parking brake. Place wheel chocks behind the rear wheels (if lifting the front) or front wheels (if using ramps).
Lifting Your Renegade Safely
If using a jack and jack stands:
- Locate the designated jack points on the front of your Renegade’s frame.
- Carefully lift the front of the vehicle until you have enough clearance to work comfortably underneath.
- Place jack stands under the frame rails near the jack points. Ensure they are stable and secure.
- Slowly lower the vehicle onto the jack stands. Give it a gentle shake to confirm stability.
If using ramps:
- Carefully drive your Renegade up the ramps until the front wheels are securely seated.
- Engage the parking brake and place wheel chocks behind the rear wheels.
No matter your method, always ensure the vehicle is stable and secure before crawling underneath.
Accessing the Oil Pan and Filter
You may need to remove a skid plate or access panel to get to the oil drain plug and filter. The 2018 Jeep Renegade often has an underbody shield. Use your socket wrench to remove the bolts holding it in place. Keep track of the bolts; they’re easy to lose.
The Nitty-Gritty: Step-by-Step Guide to Your 2018 Jeep Renegade Oil Change
Now that your Renegade is safely prepped, let’s get down to business. This is where the magic happens!
Step 1: Drain the Old Oil
Locate the oil drain plug on the bottom of the oil pan. Position your oil drain pan directly underneath it. Using the appropriate socket wrench, loosen the drain plug counter-clockwise.
Be prepared for the oil to come out quickly and hot. Once loose, carefully remove the plug by hand, letting the oil flow into the pan. This is often the messiest part, so have rags ready. Allow the oil to drain completely, which can take 10-15 minutes. While it’s draining, inspect the old drain plug and replace the crush washer if necessary.
Step 2: Replace the Oil Filter
The oil filter location varies by engine. For the 1.4L, it’s typically a cartridge filter accessible from the top of the engine bay. For the 2.4L, it’s usually a spin-on filter located near the bottom of the engine, often requiring a filter wrench.
For Spin-On Filters (2.4L):
Place your drain pan under the filter, as some oil will leak out. Use your oil filter wrench to loosen the old filter counter-clockwise. Once loose, unscrew it by hand and carefully remove it. Wipe the mounting surface clean. Apply a thin film of new oil to the rubber gasket of the new filter. Screw the new filter on by hand until the gasket makes contact, then tighten it an additional 3/4 to 1 full turn (or to the torque specification in your manual). Do not overtighten!
For Cartridge Filters (1.4L):
Locate the plastic housing on top of the engine. Use a large socket (often 24mm or 27mm) to loosen and remove the cap. Carefully pull out the old filter element. Replace the O-rings on the cap with the new ones provided with your filter. Install the new filter element into the housing, ensuring it seats correctly. Screw the cap back on and tighten it to the specified torque (usually around 18 ft-lbs or 25 Nm).
Step 3: Reinstall the Drain Plug
Once the oil has completely drained, clean the drain plug area. Install the new crush washer onto the drain plug (if applicable). Thread the drain plug back into the oil pan by hand to prevent cross-threading. Once finger-tight, use your torque wrench to tighten it to the manufacturer’s specification. This is usually around 20-25 ft-lbs (27-34 Nm) but check your manual. Do not overtighten!
Step 4: Add New Engine Oil
Remove the oil filler cap on top of the engine. Place your funnel into the oil filler neck. Slowly pour in the recommended amount of new, specified engine oil. Start with slightly less than the full capacity (e.g., 4.5 quarts for a 5.5-quart system), then check the level.
Step 5: Check the Oil Level
After adding the oil, replace the oil filler cap. Start the engine and let it run for about a minute. This allows the new oil to circulate and fill the new oil filter. Turn off the engine and wait another 5-10 minutes for the oil to settle back into the oil pan.
Carefully pull out the dipstick, wipe it clean, reinsert it fully, then pull it out again. Check the oil level. It should be between the “MIN” and “MAX” marks. Add small amounts of oil as needed, rechecking each time, until the level is correct. Do not overfill.
Post-Op: Finishing Up & What to Watch For After Your Oil Change
You’re almost done! A few final steps ensure everything is buttoned up correctly and safely.
Lowering Your Renegade and Final Checks
If you removed a skid plate, reinstall it now. Double-check all bolts are secure. Carefully lift your Renegade off the jack stands with your jack, then lower it completely to the ground. Remove wheel chocks.
Start the engine again. Look underneath for any immediate leaks around the drain plug or oil filter. Let the engine run for a few minutes, then shut it off and recheck the oil level one last time on level ground.
Resetting the Oil Life Monitor
Your 2018 Jeep Renegade has an oil life monitor system. After an oil change, you’ll need to reset it. The exact procedure can vary slightly by trim level, but it usually involves:
- Turn the ignition to the “ON/RUN” position (without starting the engine).
- Fully depress the accelerator pedal slowly three times within 10 seconds.
- Turn the ignition to the “OFF” position.
If this doesn’t work, consult your owner’s manual for the specific steps for your vehicle.
Proper Oil Disposal
Never dump used motor oil down the drain or in the trash. It’s a hazardous waste. Pour your old oil from the drain pan into the empty new oil containers. Take it to an automotive parts store, a service station, or a local recycling center that accepts used oil.
Beyond the Pavement: Oil Considerations for Off-Road Renegades
If your 2018 Jeep Renegade sees regular off-road action, your oil change intervals and choices might need special attention. Off-roading puts extra stress on your engine.
Shorter Service Intervals
Dust, dirt, water crossings, and sustained low-speed, high-load driving can accelerate oil breakdown. Consider shortening your oil change intervals by 1,000-2,000 miles if you frequently hit the trails. Your engine will thank you.
Monitoring for Contamination
After particularly dusty or wet adventures, keep an eye on your oil. If it looks excessively dark, milky (indicating water contamination), or you notice an unusual smell, it might be time for an early oil change. A quick visual inspection of the dipstick can reveal a lot.
Skid Plates and Protection
Ensure your Renegade’s underbody protection, especially the skid plate covering the oil pan, is in good condition. A rock strike to the oil pan or filter on the trail can lead to catastrophic engine failure. Consider aftermarket skid plates for enhanced protection if you’re serious about off-roading.
Common Pitfalls & Troubleshooting Your Renegade Oil Change
Even seasoned DIYers can run into snags. Here are a few common issues and how to address them.
Overtightened Drain Plug/Filter
This is why a torque wrench is your friend. Overtightening can strip threads on the oil pan or filter housing, leading to expensive repairs. If you feel excessive resistance when removing, be extra careful. Prevention is key here.
Leaking After the Oil Change
Most leaks stem from one of two places:
- Drain Plug: Check if the crush washer was replaced and if the plug is torqued correctly.
- Oil Filter: Ensure the old filter’s gasket isn’t stuck to the engine block, and the new filter’s gasket was lightly oiled and tightened correctly.
Clean the area thoroughly with brake cleaner, run the engine for a few minutes, then check again with a flashlight to pinpoint the source.
Wrong Oil Type or Capacity
Always double-check your owner’s manual. Using the wrong viscosity or an insufficient amount of oil can cause lubrication issues and engine damage. If you’ve used the wrong oil, drain it immediately and replace it with the correct type.
Frequently Asked Questions About 2018 Jeep Renegade Oil Change
How often should I change the oil in my 2018 Jeep Renegade?
Most 2018 Jeep Renegades with synthetic oil will recommend an oil change every 7,500 to 10,000 miles or once a year, whichever comes first. However, if you do a lot of towing, off-roading, or short trips in extreme temperatures, consider shortening that interval to 5,000 miles.
Can I use conventional oil instead of synthetic in my Renegade?
While technically possible in some older engines, it’s strongly discouraged for the 2018 Jeep Renegade. Both the 1.4L and 2.4L engines are designed for and perform best with full synthetic oil. Using conventional oil could lead to reduced engine protection, shorter oil life, and potential warranty issues.
What if the oil pressure light comes on after the oil change?
Immediately shut off the engine. This usually indicates a serious issue like a severe leak, incorrect oil level (too low or too high), or a faulty oil pressure sensor. Check your oil level first. If the level is correct and there are no obvious leaks, you may have a deeper problem and should consult a mechanic.
Where is the oil filter located on the 2018 Jeep Renegade 1.4L vs. 2.4L?
On the 1.4L MultiAir Turbo engine, the oil filter is a cartridge type located in a housing on top of the engine, usually near the front. For the 2.4L Tigershark MultiAir 2 engine, it’s typically a spin-on canister filter located underneath the vehicle, often on the lower front of the engine block.
Do I need to replace the drain plug gasket every time?
Yes, it’s highly recommended. The drain plug gasket (or crush washer) is designed to create a tight seal and is a single-use item. Reusing it significantly increases the risk of oil leaks, which can be messy and dangerous.
Conclusion
Performing a 2018 Jeep Renegade oil change yourself is a rewarding task that can save you money and give you a deeper understanding of your vehicle. More importantly, it ensures your Renegade’s engine stays healthy, whether you’re navigating city streets or tackling rugged trails.
By following these detailed steps, prioritizing safety, and using the right tools and materials, you’ll be able to keep your Renegade running at its best. Regular, diligent maintenance is the key to longevity and reliability, especially for a vehicle that’s built for adventure.
So, roll up your sleeves, grab your wrench, and get to it. Your Renegade (and your wallet) will thank you. Stay safe and stay comfortable out there!
