2027 Dodge Durango Maintenance Schedule, Service Costs & Ownership Guide
The 2027 Dodge Durango uses an Automatic Oil Change Indicator System with a hard cap of 10,000 miles or 12 months, whichever comes first. Spark plugs, engine coolant, and transmission fluid all reach their first replacement milestone at 100,000 miles. This guide covers every confirmed service interval, warranty term, and ownership tip, browse Durango inventory at ASA Auto Plaza throughout the process.
Maintenance Schedule
The 2027 Dodge Durango relies on an Automatic Oil Change Indicator System (OCIS) to track engine oil life in real time. The system accounts for driving habits, load, temperature, and trip length, so the interval varies by driver. The system may trigger a change as early as 3,500 miles for severe duty, or as late as 10,000 miles for typical highway use. Regardless of what the monitor shows, Dodge mandates a synthetic oil and filter change no later than every 10,000 miles or 12 months, whichever arrives first.
Minnesota winters and gravel roads around the Jackson area qualify as demanding driving conditions. If you regularly tow a trailer, make frequent short cold-weather trips, or haul maximum payload loads, the OCIS will shorten the interval accordingly. Follow the system, and let it guide you rather than relying on a fixed mileage number alone.

Service Costs & What to Expect
The service cost picture for the 2027 Durango varies by trim, because three distinct engines power this lineup. The GT HEMI runs the 5.7L HEMI V8 (oil capacity: 7 quarts), the R/T 392 uses the 6.4L HEMI V8 (oil capacity: 7 quarts), and the SRT Hellcat carries the supercharged 6.2L HEMI V8 (oil capacity: 8.3 quarts). The R/T 392 and SRT Hellcat both require premium 91-octane fuel; the GT HEMI runs on regular 87 octane (with mid-grade 89 octane recommended). Factor fuel grade into the full cost of ownership when comparing trims.
What each service visit covers:
A standard OCIS-triggered service visit bundles oil and filter replacement with tire rotation, brake inspection, battery check, and a cooling system and exhaust review. Combining these items in a single visit keeps the Durango's high-displacement V8 engines running cleanly and protects the braking hardware, which includes Brembo four-wheel disc setups on R/T 392 and SRT Hellcat trims.
The 100,000-mile service is the most significant scheduled stop. Spark plug replacement, coolant flush, and transmission fluid service all fall at that milestone. Planning for this combined service in advance prevents three separate shop visits.
Engine air filter inspection is required at every 10,000-mile interval if the vehicle is driven in dusty or off-road conditions. In areas with gravel roads or agricultural dust, this inspection should not be deferred.
EPA fuel economy ratings for the 2027 Dodge Durango
Fuel economy by engine (EPA-rated):
- 5.7L HEMI GT: 14 city / 21 highway / 16 combined mpg
- 6.4L HEMI R/T 392: 13 city / 19 highway / 15 combined mpg
- 6.2L Supercharged SRT Hellcat: 12 city / 17 highway / 14 combined mpg (combined for SRT Hellcat confirmed at 13 or 14 mpg depending on source; defer to fueleconomy.gov for the most current figure)
The 24.6-gallon fuel tank is standard across all trims, giving the GT HEMI a usable highway range well over 500 miles per fill.

Common Ownership Questions
How long does a Dodge Durango typically last?
HEMI V8 engines are known for high mileage durability when maintained on schedule. Many Durango owners report 200,000-plus miles with consistent oil changes and powertrain service. The 5.7L HEMI is the most proven longevity platform in this lineup, but all three engines respond well to clean oil and scheduled inspections.
Does the 5.7L HEMI have cylinder deactivation?
Yes. The 5.7L HEMI uses Fuel Saver Technology with eight deactivating lifters. Under light loads and highway cruising, the engine shifts to four-cylinder operation to reduce fuel consumption. This is a normal function. If the oil is not kept fresh with the correct synthetic fluid, the lifters and deactivating mechanism are among the first components affected.
What fuel does the R/T 392 or SRT Hellcat require?
Both require premium 91-octane fuel. This is not a recommendation, it is a hard requirement for both the 6.4L and the supercharged 6.2L HEMI. Using regular fuel in either engine over time can cause knock and reduce power output. The GT HEMI accepts regular 87 octane but runs optimally on mid-grade 89 octane.
Is AWD standard on all 2027 Durango trims?
All-wheel drive is standard on every HEMI V8 trim. RWD is only available on the base GT RWD configuration. Every GT HEMI, R/T 392, and SRT Hellcat trim comes standard with AWD, which is a significant ownership advantage for Minnesota winters.
How does towing affect service intervals?
Towing is classified as severe-duty use. The OCIS will shorten oil change intervals when the Durango is operated under tow loads frequently. With the Tow 'n Go package, the GT HEMI reaches 8,700 lbs. of towing capacity. The R/T 392 and SRT Hellcat carry 8,700 lbs. of towing capacity standard. Towing regularly will also increase the frequency of brake and suspension inspections.

Frequently Asked Questions
How often does the 2027 Dodge Durango need an oil change?
The 2027 Durango must have a synthetic oil and filter change no later than every 10,000 miles or 12 months, whichever comes first. The Automatic Oil Change Indicator System will alert you sooner if driving conditions are severe, and the interval may be as short as 3,500 miles. Always follow the OCIS prompt, and never exceed the 10,000-mile hard cap.
What type of oil does the 2027 Dodge Durango use?
The R/T 392 and SRT Hellcat models specify 0W-40 Pennzoil Ultra Synthetic as the factory fill. For the GT HEMI 5.7L, consult your owner's manual or ask the ASA Auto Plaza service team for the correct grade, as the spec sheet does not list a separate factory fill designation for that engine.
When do spark plugs need replacing on the 2027 Durango?
Spark plugs are replaced at 100,000 miles on the 2027 Dodge Durango. This milestone also coincides with engine coolant replacement and transmission fluid service, making it efficient to address all three at one visit.
What is the warranty on the 2027 Dodge Durango?
The 2027 Durango carries a 3-year / 36,000-mile bumper-to-bumper warranty and a 5-year / 60,000-mile powertrain warranty covering the engine, transmission, and axles. Roadside assistance is included for 5 years or 60,000 miles. Extended protection is available through Mopar Vehicle Protection programs.
Does the SRT Hellcat need more frequent service than the GT HEMI?
The SRT Hellcat has a larger oil capacity (8.3 quarts vs. 7 quarts) and requires premium 91-octane fuel, but the core service intervals are the same across all Durango trims. High-performance driving, track use, or frequent towing will prompt the OCIS to shorten oil change intervals regardless of which engine is under the hood.
Is tire rotation included at every Durango service visit?
Yes. Tire rotation and brake inspection are specified at every 10,000-mile service interval, which aligns with each OCIS-triggered oil change visit. Handling both at the same time ensures neither is deferred.
