The standard engine oil for the 2018 Dodge Journey is 5W-20, typically full synthetic. Use the exact specification listed in the owner's manual or on the oil fill cap for your engine variant to be sure.
There are two engines offered in the 2018 Journey—the 2.4L I4 and the 3.6L V6—and both typically call for a 5W-20 grade, though confirming the exact spec for your model is important. The owner's manual is the definitive source, and dealer parts counters can help confirm the right viscosity and approval for your region.

Oil change intervals and maintenance tips
Intervals depend on the oil type you use and your driving conditions. In general, synthetic 5W-20 oils allow longer intervals than conventional oil, but always follow the owner's manual and service reminders. If you use conventional oil, shorter change intervals are typical.
- Park the vehicle on level ground and engage the parking brake.
- Let the engine cool before draining oil to avoid burns and excessive oil loss.
- Drain the old oil into a proper container and replace the oil drain plug securely.
- Replace the oil filter with a new one that matches the engine and oil type.
- Refill with the correct amount and grade of oil as specified for your engine.
- Check for leaks and ensure the oil level is within the recommended range on the dipstick.
- Reset oil-change indicator light if equipped and record the service date and mileage.
- Dispose of used oil and filter at an appropriate recycling facility.
Always consult the owner’s manual for the exact oil type, capacity, and change interval for your vehicle and engine variant. If in doubt, contact a dealer or qualified technician.
Summary
For a 2018 Dodge Journey, the typical recommendation is 5W-20 engine oil, suitable as a full synthetic or synthetic blend, regardless of whether your model uses the 2.4L I4 or the 3.6L V6. Confirm the exact specification in the owner’s manual or on the oil fill cap, and follow the prescribed change intervals. Use a reputable brand that meets the stated API/ILSAC standards and replace the oil filter at each change. Regularly verify oil level and leaks to maintain engine health.
