The 2019 Jeep equipped with the 3.6-liter Pentastar V6 uses 0W-20 synthetic motor oil.
Oil type and specifications
The 3.6L Pentastar is designed to run on a full synthetic 0W-20 oil that meets API SN or higher and ILSAC GF-5 standards. The oil capacity with a new filter is approximately 6 quarts (5.7 liters). For routine maintenance, Jeep commonly recommends changing the oil every 7,500 miles or 12 months when using synthetic oil, with shorter intervals under severe driving conditions. Always verify the exact specification in your owner's manual or with a dealer, as regional requirements or warranty considerations can apply.
Here are the precise specifications and certifications to look for when buying oil for your 2019 Jeep 3.6.
- Oil grade: 0W-20 synthetic motor oil
- Certifications: API SN or higher (often SN+, SM, or newer) and ILSAC GF-5 or higher
- Capacity: 6 quarts (approximately 5.7 liters) with a new oil filter
- Recommended change interval (synthetic): around 7,500 miles or 12 months under normal driving
Sticking to these specifications helps protect the engine, maximize fuel efficiency, and maintain warranty eligibility.
Climate and driving considerations
In extremely cold or hot climates, or in cases of frequent towing, severe service, or predominantly short trips, consult the owner’s manual or your dealer for any climate-specific recommendations. If in doubt, err on the side of a higher-quality synthetic oil and/or shorter service intervals.
Maintenance planning and practical tips
To ensure you’re using the correct oil and maintaining your 3.6L engine, follow these practical steps when planning an oil change:
- Confirm the exact viscosity and specifications in your owner’s manual for your model and region
- Use a high-quality oil filter and a reputable synthetic 0W-20 motor oil that meets API SN or higher
- Proceed with a 6-quart fill (plus filter) and recheck the level after running the engine for a few minutes
- Record the oil change in your maintenance log to track intervals
Adhering to these steps helps ensure optimal lubrication, engine longevity, and proper warranty documentation.
