The 2018 Jeep Compass equipped with the typical 2.4-liter Tigershark engine requires 0W-20 synthetic motor oil (MS-6395). The engine holds about 5.5 quarts with a filter. Always verify the exact specification in your owner's manual for your vehicle’s exact configuration.
This article provides a clear overview of the official oil type for the 2018 Compass, notes on variations by engine or market, and practical maintenance guidance to help you keep your SUV running smoothly.
Oil type and specification
Below are the official oil standards commonly cited for the 2018 Compass’s primary engine option in North America. The guidance focuses on the grade and the standard it must meet.
- 0W-20 synthetic motor oil that meets FCA/MS-6395 specification
- Full-synthetic 0W-20 from reputable brands (e.g., Mobil 1, Pennzoil, Castrol) that meet the MS-6395 standard
- Avoid using oils that do not meet MS-6395 or that are significantly outside the recommended viscosity
Using oil that meets the FCA MS-6395 specification is essential for proper lubrication, fuel economy, and engine longevity. If you cannot obtain 0W-20 that meets MS-6395, consult your dealer or owner’s manual for alternatives.
Oil capacity and change interval
Knowing the capacity and how often to change the oil helps you plan maintenance and avoid damage. The information below covers typical figures for the 2018 Compass with the 2.4L engine.
- Oil capacity: approximately 5.5 quarts with filter
- Change interval: typically every 6,000–7,500 miles under normal driving with synthetic oil, or as indicated by the vehicle’s oil life monitor; more frequent changes may be warranted in severe conditions
Regular oil level checks and adherence to the oil life monitor will help ensure you stay within recommended service intervals and protect the engine over time.
Market variations and engine options
While the U.S. market commonly used the 2.4-liter Tigershark engine in 2018, other markets offered different configurations that may require alternate viscosities or specifications. Always check the exact engine in your vehicle and consult the owner’s manual or a Jeep dealer if you’re unsure.
North America — typical configuration
Most 2018 Compass models sold in the United States used the 2.4L Tigershark engine, with the 0W-20 synthetic MS-6395 oil recommendation described above.
Other regions — alternative engines
Some export markets used different gasoline engines or transmissions, which can change the recommended viscosity and specification. For any non-U.S. Compass, verify the exact engine code and oil spec in the local owner's manual.
Practical tips for maintaining the right oil
To help ensure you’re using the correct oil and maintain optimal performance:
- Always purchase oil that is labeled 0W-20 and meets FCA MS-6395
- Use a quality oil filter and follow the recommended drain interval
- Record the oil change in your maintenance log and reset any oil life monitor as required
Sticking to the recommended oil type and schedule helps protect the engine’s seals, maintain fuel efficiency, and preserve resale value.
