What Oil Does A 2018 Jeep Compass Take: Oil Guide
Reading Time: 5 minutes For a U.S.-market 2018 Jeep Compass with the 2.4L engine, use SAE 0W-20 engine oil that meets FCA Material Standard MS-6395. The oil capacity is about 5.0 US quarts (4.7 liters) with a filter change.
Check the oil cap and the 2018 Jeep Compass owner’s manual to confirm the specification for your vehicle. If your Compass was built for a market outside the United States or has a different engine, its oil requirements may differ.
Recommended oil for a 2018 Jeep Compass
The recommended oil for the U.S. 2018 Compass 2.4L engine is SAE 0W-20 with the MS-6395 specification. SAE 0W-20 describes the oil’s viscosity grade; MS-6395 is the manufacturer’s material standard.
| Item | Specification |
|---|---|
| Engine covered | 2.4L gasoline engine |
| Oil viscosity | SAE 0W-20 |
| Required standard | FCA Material Standard MS-6395 |
| Approximate capacity with filter | 5.0 US qt (4.7 L) |
When buying oil, check both the viscosity and the standard on the container. A bottle marked 0W-20 is not automatically the right choice if it does not also meet the required specification.
How much oil does a 2018 Jeep Compass need?
The 2.4L engine takes about 5.0 US quarts, or 4.7 liters, when the oil filter is changed. Treat this as an approximate fill amount, not a reason to pour in all five quarts without checking the level.
After an oil change, park on level ground and check the dipstick. Add oil gradually if the level is low, then check again. Keeping the oil between the dipstick’s marks helps prevent both underfilling and overfilling.
How to choose the right oil
Choose oil by matching the grade and specification—not just the brand. The label should show SAE 0W-20 and state that the oil meets FCA MS-6395.
You may find conventional, synthetic-blend, or full-synthetic oils in this grade. The key check is whether the product meets the required standard; do not assume that any oil labeled “synthetic” is suitable. If the label is unclear, ask the oil maker or a qualified service shop to confirm the specification before use.
How to check and add engine oil
Check the oil on level ground, with the engine off. If you have just driven, give the oil time to drain back into the engine before reading the dipstick.
- Open the hood and locate the engine-oil dipstick.
- Pull it out and wipe it clean with a lint-free cloth.
- Push it fully back in, then remove it again to read the level.
- If the level is low, add a small amount of the correct oil through the oil-fill opening.
- Wait briefly, then check the dipstick again. Repeat only as needed.
Do not fill above the dipstick’s upper mark. If the oil-pressure warning light stays on, or the engine makes unusual knocking sounds, stop driving as soon as it is safe and have the vehicle checked.
Common oil mistakes to avoid
Using the wrong grade or missing the required oil standard can make it harder to ensure the engine has the protection specified by Jeep. Check the bottle label before pouring, even if the oil is the same brand you used before.
Also avoid these common errors:
- Adding oil based only on the stated capacity: Check the dipstick after filling.
- Overfilling: Too much oil can cause problems; keep the level within the dipstick marks.
- Confusing engine oil with transmission fluid: They serve different systems and are not interchangeable.
- Using a generic change interval without checking the manual: Follow the vehicle’s oil-life system and maintenance schedule.
- Ignoring a persistent warning light or leak: Have the cause checked rather than repeatedly topping up without finding the source.
FAQs
Does a 2018 Jeep Compass use synthetic oil?
The important requirement is SAE 0W-20 oil that meets FCA MS-6395. Check the owner’s manual and the oil label for the requirements that apply to your vehicle; do not choose oil based on the word “synthetic” alone.
Can I use 5W-20 instead of 0W-20?
Use the specified 0W-20 unless the owner’s manual for your exact vehicle says otherwise. Do not substitute another grade based only on climate or advice meant for a different model year.
Does the five-quart capacity include the oil filter?
The approximate 5.0-quart capacity is for an oil change with a new filter. Check the dipstick after service because the amount needed can vary slightly.
How often should I change the oil?
Follow the Compass oil-life monitor and the maintenance schedule in the owner’s manual. Driving conditions can affect service needs, so a generic mileage interval may not fit every vehicle.
What if my Compass was sold outside the United States?
Do not assume the U.S. 2.4L specification applies. Check the manual for your market and engine, or confirm the correct oil specification with a Jeep dealer using your vehicle identification number (VIN).
Bottom line
For a U.S.-market 2018 Jeep Compass with the 2.4L engine, use SAE 0W-20 meeting FCA MS-6395. The approximate refill amount is 5.0 US quarts (4.7 liters) with a new filter. Confirm the level with the dipstick and use the owner’s manual or VIN-based dealer guidance if your vehicle’s engine or market differs.
