2018 Dodge Journey 3.6 oil capacity and type are critical specifications for maintaining the longevity and performance of your vehicle’s engine. Understanding these details ensures you provide your SUV with the precise lubrication it needs, preventing potential issues and costly repairs down the road. For owners of the 2018 Dodge Journey equipped with the robust 3.6L Pentastar V6 engine, adhering to manufacturer recommendations for oil is not just good practice; it’s essential for a smooth and reliable driving experience across North American roads.
The Heart of Your Journey: Why Proper Oil Matters
The engine oil in your 2018 Dodge Journey’s 3.6L Pentastar V6 acts as the lifeblood of the engine. Its primary functions include lubricating moving parts to reduce friction and wear, cooling engine components by carrying away heat, cleaning the engine by suspending dirt and contaminants, and protecting against rust and corrosion. Over time, engine oil breaks down, loses its effectiveness, and accumulates impurities. Using the correct type and quantity of oil, and changing it at recommended intervals, is paramount for:
Optimal Engine Performance: A well-lubricated engine runs more efficiently, providing better power and fuel economy.
Extended Engine Life: Reduced wear on critical components prevents premature failure.
Preventing Overheating: Oil helps dissipate heat, preventing engine damage from excessive temperatures.
Maintaining Warranty: Most manufacturer warranties require adherence to specific maintenance schedules and fluid specifications.
Understanding Your 2018 Dodge Journey 3.6 Oil Capacity
Knowing the exact oil capacity for your 2018 Dodge Journey with the 3.6-liter Pentastar V6 engine is the first step in proper maintenance.
For the 2018 Dodge Journey 3.6L V6 engine, the recommended oil capacity, when performing an oil change that includes replacing the oil filter, is approximately 5.9 to 6.0 quarts (or roughly 5.6 to 5.7 liters).
It’s crucial to understand that this capacity is an approximate guideline. Always verify the oil level using your vehicle’s dipstick after adding the specified amount and running the engine briefly. Here’s why:
Oil Filter Absorption: A new oil filter will absorb some oil, so adding the full amount and checking the dipstick ensures the system is adequately filled.
Residual Oil: A small amount of old oil might remain in the engine even after draining, which can slightly affect the required refill amount.
Dipstick Accuracy: The dipstick provides the most accurate reading of the actual oil level in your engine’s crankcase. Ensure the vehicle is on level ground and the engine has been turned off for a few minutes (to allow oil to drain back into the pan) before checking.
Never overfill the engine with oil, as this can lead to foaming, reduced lubrication effectiveness, and potential damage to seals and other components. Likewise, underfilling can cause excessive friction and heat, leading to significant engine wear.
Choosing the Right 2018 Dodge Journey 3.6 Oil Type
The type of oil you use in your 2018 Dodge Journey’s 3.6L Pentastar V6 engine is just as important as the quantity. Modern engines, like the Pentastar, are designed with specific oil requirements to maximize their performance and longevity.
For the 2018 Dodge Journey 3.6L Pentastar V6, Chrysler (now Stellantis) specifically recommends engine oil meeting the following specifications:
Viscosity: SAE 5W-20
API Service Classification: Oil that meets API Service Category SN, SM, or SL. Always aim for the latest API specification available (e.g., API SN Plus or SP) as these typically offer enhanced protection against low-speed pre-ignition (LSPI), a common concern in modern direct-injection engines.
Chrysler Material Standard: The oil must meet Chrysler Material Standard MS-6395. This standard ensures the oil has been tested and approved for use in Chrysler, Dodge, Jeep, and Ram vehicles, providing the specific additive package required for the engine’s design.
Understanding Oil Types: Conventional vs. Synthetic vs. Synthetic Blend
While the primary recommendation is for an oil meeting the above specifications, it’s worth understanding the different oil formulations:
Conventional Oil: Derived directly from crude oil, it’s the least expensive but offers less protection against extreme temperatures and wear compared to synthetics. It typically requires more frequent changes.
Synthetic Blend Oil: A mix of conventional and synthetic base oils. It offers better protection and performance than conventional oil at a more affordable price than full synthetic.
Full Synthetic Oil: Engineered in laboratories to provide superior lubrication, wear protection, and resistance to thermal breakdown. Given the advanced nature of the 3.6L Pentastar engine and its performance demands, using a high-quality full synthetic oil that meets the specified API and MS-6395 standards is highly recommended, even if not explicitly mandated by the owner’s manual for all conditions. Full synthetic oils often allow for longer oil change intervals.
Always refer to your vehicle’s owner’s manual for the definitive and most up-to-date oil recommendations, as specifications can sometimes be updated.
Oil Change Intervals for Your 2018 Dodge Journey 3.6L
Dodge typically recommends oil change intervals based on mileage or time, whichever comes first. For most driving conditions with your 2018 Dodge Journey 3.6L:
Normal Driving Conditions: Generally, oil changes are recommended every 6 months or 10,000 miles (16,000 km), whichever occurs first, when using the specified engine oil.
Severe Duty Conditions: If you frequently drive in severe conditions (e.g., short trips, extreme temperatures, heavy towing, dusty environments, extensive idling), you may need to change your oil more frequently, possibly every 3,000 to 5,000 miles (4,800 to 8,000 km).
Your vehicle’s oil change indicator system will also alert you when an oil change is due. This system monitors various factors to determine the optimal time for an oil change. It’s a good practice to follow its recommendations.
DIY Oil Change Considerations
If you plan to perform an oil change yourself, ensure you have:
The correct amount and type of new oil (SAE 5W-20, API SN/SP, MS-6395).
A new oil filter that matches your 2018 Dodge Journey 3.6L.
An oil filter wrench, a drain pan, and a socket for the drain plug.
Safety equipment like gloves and eye protection.
A funnel for adding new oil.
A plan for proper disposal of the used oil at an authorized recycling center.
Always consult your owner’s manual for detailed, step-by-step instructions and torque specifications for the drain plug.
Conclusion
Maintaining your 2018 Dodge Journey 3.6L Pentastar V6 engine with the correct oil capacity and type is a straightforward yet crucial aspect of vehicle ownership. By consistently using SAE 5W-20 oil that meets API SN/SP and Chrysler MS-6395 standards, and ensuring you fill to the correct 5.9-6.0 quart capacity, you’ll contribute significantly to the engine’s long-term health, performance, and fuel efficiency. Regular oil changes according to the manufacturer’s recommended intervals will keep your Journey running smoothly, mile after reliable mile.
