Keeping Your 2018 Dodge Durango Running Smoothly: A Guide to Oil Capacity and Type
The 2018 Dodge Durango is a versatile and powerful SUV, beloved by families and performance enthusiasts alike across North America. To ensure your Durango continues to deliver reliable performance and longevity, understanding its specific oil capacity and the recommended oil type is paramount. Proper lubrication is the lifeblood of your engine, protecting its intricate components from wear, dissipating heat, and helping maintain optimal fuel efficiency. Skimping on this vital aspect of maintenance can lead to costly repairs and reduced engine lifespan.
Understanding Your 2018 Dodge Durango’s Engine Options
One of the first things to recognize when discussing oil specifications for the 2018 Dodge Durango is that Dodge offered several robust engine options. Each engine has unique lubrication requirements. Knowing which engine powers your Durango is the first step in ensuring you’re using the correct oil.
The primary engine options for the 2018 model year were:
3.6L Pentastar V6: A popular and efficient choice, known for its balance of power and fuel economy.
5.7L HEMI V8: A more powerful option, delivering a significant boost in horsepower and torque, ideal for towing and spirited driving.
6.4L SRT HEMI V8: Exclusively found in the high-performance SRT model, this engine is a powerhouse designed for maximum exhilaration.
Each of these engines requires a specific amount and type of oil to function correctly, which we’ll delve into next.
2018 Dodge Durango Oil Capacity by Engine Type
Getting the oil capacity right is crucial. Too little oil can lead to inadequate lubrication and overheating, while too much can cause aeration, foaming, and increased pressure, potentially damaging seals. Here are the recommended capacities for each engine found in the 2018 Dodge Durango:
3.6L Pentastar V6 Engine:
Oil Capacity: 6 quarts (5.7 liters)
This capacity includes the oil filter. Always ensure you replace the oil filter during every oil change.
5.7L HEMI V8 Engine:
Oil Capacity: 7 quarts (6.6 liters)
Like the V6, this capacity includes the oil filter. A new filter is a must-have for every oil service.
6.4L SRT HEMI V8 Engine:
Oil Capacity: 7 quarts (6.6 liters)
Again, this capacity includes the oil filter, which should always be replaced.
Important Note: While these figures are standard, always double-check your vehicle’s owner’s manual for the most accurate and up-to-date information specific to your VIN. Minor variations can sometimes occur, and the owner’s manual is the definitive source. After refilling, start the engine for a minute to circulate the oil, then shut it off, wait a few minutes for the oil to settle, and check the dipstick to ensure the level is within the safe operating range.
Choosing the Right Oil Type for Your 2018 Dodge Durango
Selecting the correct oil viscosity and specification is just as critical as capacity. Using the wrong oil can compromise engine protection and even void your warranty. Modern engines, like those in the 2018 Durango, are designed with specific oil requirements in mind.
Here are the recommended oil types based on the engine:
3.6L Pentastar V6 Engine:
Recommended Oil Type: SAE 5W-20 Full Synthetic engine oil.
Specification: It must meet Chrysler Material Standard MS-6395. Look for oils that are API certified (SN Plus or SP rating).
5.7L HEMI V8 Engine:
Recommended Oil Type: SAE 5W-20 Full Synthetic engine oil.
Specification: It must meet Chrysler Material Standard MS-12633. Look for oils that are API certified (SN Plus or SP rating).
6.4L SRT HEMI V8 Engine:
Recommended Oil Type: SAE 0W-40 Full Synthetic engine oil.
Specification: It must meet Chrysler Material Standard MS-12991. Look for oils that are API certified (SN Plus or SP rating).
Why Full Synthetic?
While older vehicles might have used conventional or synthetic blend oils, the advanced engineering of the 2018 Durango’s engines benefits immensely from full synthetic oil. Full synthetic oils offer superior protection against wear, better thermal stability (especially crucial for high-performance HEMI engines), improved flow in cold weather, and enhanced resistance to breakdown over time. This translates to extended oil change intervals, better engine cleanliness, and ultimately, a longer-lasting engine.
Beyond Capacity and Type: The Importance of Regular Oil Changes
Knowing the right oil capacity and type is only half the battle; adhering to a regular oil change schedule is the other. Engine oil degrades over time and mileage, losing its protective properties due to heat, contamination, and shearing.
Benefits of Regular Oil Changes:
Engine Longevity: Fresh oil reduces friction and wear on critical engine components.
Optimal Performance: Clean oil ensures parts move freely, contributing to peak engine performance.
Fuel Efficiency: Worn-out oil increases friction, forcing the engine to work harder and consume more fuel.
Heat Dissipation: Oil helps draw heat away from the engine, preventing overheating.
Contaminant Removal: The oil filter captures harmful particles, but the oil itself holds contaminants in suspension until it’s drained.
For most 2018 Dodge Durangos using full synthetic oil, the recommended oil change interval is typically every 10,000 miles (16,000 kilometers) or 12 months, whichever comes first. However, if you frequently drive in severe conditions (e.g., heavy towing, extreme temperatures, dusty environments, or frequent short trips), more frequent oil changes might be necessary. Always refer to your owner’s manual for the specific maintenance schedule tailored to your driving habits.
A Quick Guide to the Oil Change Process
While many choose a professional service, changing your own oil can be a rewarding DIY task. If you plan to do it yourself:
1. Gather Supplies: Correct oil, new oil filter, drain pan, wrench for drain plug, oil filter wrench, funnel, rags.
2. Warm the Engine: Run the engine for a few minutes to warm the oil, making it flow more easily.
3. Locate and Drain: Safely lift the vehicle, place the drain pan under the oil pan, and carefully remove the drain plug.
4. Replace Filter: Once the oil has fully drained, replace the old oil filter with a new one, ensuring you lubricate the new filter’s gasket with a little fresh oil.
5. Refill: Reinstall the drain plug securely, then lower the vehicle and carefully pour in the specified amount of new oil using a funnel.
6. Check Level: Start the engine briefly, then shut it off. Wait a few minutes for the oil to settle, and check the dipstick to confirm the oil level is correct.
7. Proper Disposal: Never dispose of used oil down the drain. Take it to an authorized recycling center or auto parts store.
Final Thoughts on Your Durango’s Engine Health
Taking a proactive approach to your 2018 Dodge Durango’s maintenance, particularly concerning its oil, is a sound investment. By using the correct oil capacity and type – whether it’s the 6 quarts of 5W-20 for the Pentastar V6 or the 7 quarts of 0W-40 for the SRT HEMI – and adhering to regular change intervals, you’re ensuring your SUV’s engine performs at its best for years to come. Your Durango is a robust vehicle, and with the right care, it will continue to be a reliable companion on all your adventures.
