Selecting the right oil for a 2018 Jeep Compass means checking for the correct API certification and viscosity grade recommended by the manufacturer. Many owners wonder what kind of oil does a 2018 jeep compass take, and the answer is simpler than you might think. This guide covers everything from oil weight to synthetic blends, so you can keep your engine running smoothly.
Your 2018 Jeep Compass needs 0W-20 full synthetic oil. This is the factory fill for both the 2.4L Tigershark engine and the 1.4L MultiAir turbo engine. Using the wrong oil can lead to poor fuel economy, increased wear, or even engine damage over time.
What Kind Of Oil Does A 2018 Jeep Compass Take
Let’s break down the exact specifications. The 2018 Jeep Compass requires SAE 0W-20 full synthetic motor oil that meets API SN or higher certification. For the 2.4L engine, the oil capacity is 5.5 quarts with a filter change. The 1.4L turbo engine takes about 4.5 quarts.
Jeep recommends using oils that carry the API Starburst certification mark. This ensures the oil meets current industry standards for protection and performance. Always check the bottle for this logo before pouring.
Viscosity Grades Explained
Viscosity refers to how thick or thin the oil is at different temperatures. The “0W” part means the oil flows well in cold weather, down to -30°F. The “20” indicates its thickness at normal operating temperature. This combination provides excellent protection during cold starts and steady driving.
Using a thicker oil like 5W-30 or 10W-30 is not recommended. It can reduce fuel economy and may not circulate quickly enough during cold starts. Stick with 0W-20 for best results.
Synthetic Vs Conventional Oil
Full synthetic oil is required for the 2018 Compass. Conventional oil does not provide the same level of protection for modern engines with tight tolerances and variable valve timing. Synthetic oil resists breakdown better, handles higher temperatures, and extends oil change intervals.
Some owners ask about synthetic blends. While they are better than conventional oil, they still don’t match full synthetic performance. For the Compass, stick with full synthetic 0W-20.
Oil Capacity And Specifications By Engine
Knowing the exact capacity helps you buy the right amount. Here’s a quick reference for both engines available in the 2018 Jeep Compass.
- 2.4L Tigershark I4 Engine: Oil capacity is 5.5 quarts (5.2 liters) with filter. Requires 0W-20 full synthetic.
- 1.4L MultiAir Turbo I4 Engine: Oil capacity is 4.5 quarts (4.3 liters) with filter. Requires 0W-20 full synthetic.
Always verify your engine type by checking the owner’s manual or the sticker under the hood. The 2.4L is more common in the Latitude and Limited trims. The 1.4L turbo appears in the Trailhawk and certain Sport models.
Recommended Oil Brands For 2018 Jeep Compass
You don’t have to use Mopar oil, but it’s a safe choice. Many quality brands meet the required specifications. Here are some top picks:
- Pennzoil Platinum Full Synthetic 0W-20
- Mobil 1 Advanced Fuel Economy 0W-20
- Castrol EDGE Full Synthetic 0W-20
- Valvoline Advanced Full Synthetic 0W-20
- Amazon Basics Full Synthetic 0W-20 (budget option)
All these oils carry the API SN Plus or SP certification, which is fine for your 2018 Compass. Check the label for the API donut symbol to be sure.
How To Check And Change Oil In A 2018 Jeep Compass
Regular oil changes keep your engine healthy. Here’s a step-by-step guide for checking oil level and performing a change.
Checking Oil Level
- Park on level ground and let the engine cool for 5-10 minutes.
- Pull the dipstick out (yellow handle near the front of the engine).
- Wipe it clean with a rag, then reinsert fully.
- Pull it out again and check the oil level. It should be between the two marks.
- If low, add 0W-20 oil in small increments, checking between additions.
Do not overfill. Too much oil can cause foaming and pressure issues. The difference between the low and full marks is about one quart.
Oil Change Procedure
- Gather supplies: 5-6 quarts of 0W-20 full synthetic oil, a new oil filter (Mopar 4892339AA or equivalent), a drain pan, a wrench, and a filter wrench.
- Warm the engine slightly (run for 2-3 minutes) to help oil drain faster.
- Jack up the front of the vehicle and secure it on jack stands. Never work under a car supported only by a jack.
- Locate the drain plug under the oil pan. It’s a 13mm or 15mm bolt depending on the engine.
- Place the drain pan under the plug, then remove the plug with a wrench. Let oil drain completely.
- Remove the old oil filter. It’s usually near the front of the engine, accessible from below or above.
- Lubricate the new filter’s rubber gasket with a little fresh oil. Install hand-tight, then tighten an additional 3/4 turn.
- Reinstall the drain plug and tighten to 20-25 ft-lbs. Do not overtighten.
- Lower the vehicle and add new oil. For the 2.4L, add about 5 quarts first, then check and top off. For the 1.4L, start with 4 quarts.
- Start the engine and let it run for 30 seconds. Check for leaks around the filter and drain plug.
- Turn off the engine, wait 5 minutes, then check the dipstick. Add oil as needed to reach the full mark.
Dispose of used oil properly. Most auto parts stores accept used oil for recycling.
Oil Change Interval For 2018 Jeep Compass
Jeep recommends changing the oil every 6,000 miles or 6 months, whichever comes first. However, if you drive in severe conditions—like extreme temperatures, dusty roads, or frequent short trips—consider changing it every 4,000 to 5,000 miles.
The oil life monitor in your Compass will alert you when a change is due. It calculates based on driving habits and conditions. Don’t ignore the warning light.
Using full synthetic oil allows for longer intervals compared to conventional oil. But sticking to the 6,000-mile schedule is safe and keeps your warranty valid.
Signs You Need An Oil Change Sooner
- Oil level drops quickly between changes (possible leak or consumption issue).
- Oil looks dark and gritty on the dipstick.
- Engine sounds louder or rougher than usual.
- Check engine light comes on, especially if related to oil pressure.
- Oil change reminder appears on the dashboard.
If you notice any of these, check your oil level and condition immediately. Don’t wait for the scheduled interval.
Common Oil-Related Questions For 2018 Jeep Compass
Here are answers to frequent questions owners ask about oil for this vehicle.
Can I Use 5W-30 Instead Of 0W-20?
No, it’s not recommended. The engine is designed for 0W-20 viscosity. Using 5W-30 can reduce fuel economy and may not provide proper protection during cold starts. Stick with 0W-20.
Is Synthetic Blend Okay?
Full synthetic is best, but a synthetic blend is better than conventional oil. If you’re in a pinch, a blend won’t cause immediate damage. However, for long-term performance, use full synthetic.
How Often Should I Check The Oil?
Check the oil level every time you fill up with gas, or at least once a month. This helps catch low levels early. Also check before long trips.
What Happens If I Use The Wrong Oil?
Using the wrong viscosity can cause increased engine wear, reduced fuel economy, and potential sludge buildup. In extreme cases, it may void your warranty if damage occurs. Always follow the manufacturer’s recommendation.
Do I Need To Use Mopar Oil Filter?
No, but use a high-quality filter that meets OEM specifications. Brands like Fram, Purolator, and Wix make compatible filters. The Mopar filter is a safe choice, but aftermarket options work fine.
Cost Of An Oil Change For 2018 Jeep Compass
Doing it yourself costs about $35 to $50 for oil and a filter. A professional oil change at a dealership or quick-lube shop runs $60 to $90. Prices vary by location and brand of oil used.
If you take it to a shop, ask what oil they use. Some shops use bulk oil that may not be full synthetic. Confirm they use 0W-20 full synthetic with API certification.
Using a coupon or membership discount can lower the cost. Many shops offer first-time customer deals or loyalty programs.
Environmental Considerations
Used motor oil is hazardous waste. Never pour it down the drain, on the ground, or in the trash. Take it to a recycling center or auto parts store. Many stores accept up to 5 gallons per visit.
Recycling oil helps protect the environment and conserves resources. One gallon of used oil can be re-refined into the same amount of new oil.
Also, consider using eco-friendly oil brands that focus on sustainable sourcing. Some brands like Castrol EDGE and Mobil 1 have recycling programs.
Final Tips For Maintaining Your 2018 Jeep Compass
Keep a log of oil changes, including mileage and date. This helps track intervals and is useful if you sell the vehicle. Use the same brand and type of oil consistently to avoid mixing additives.
If you drive in extreme conditions—like towing, off-roading, or very hot climates—consider changing oil more frequently. The 1.4L turbo engine may benefit from slightly shorter intervals due to higher heat.
Always check the owner’s manual for the most accurate information. It contains specific details for your trim level and engine. The manual is your best friend for maintenance.
Finally, don’t skip oil changes. Regular maintenance is the cheapest way to avoid expensive repairs. A well-lubricated engine lasts longer and performs better.
