PREMIER CAPE COD CDJR • MAINTENANCE
Factory service intervals, fluids and ownership care by engine.
Summer stop-and-go travel on Route 6 and commuting on Route 3 add engine hours even at modest mileage. Our Hyannis service team works with Durango drivers near Falmouth, Plymouth, Barnstable and Marion on the engine-specific factory schedule.
The 2027 Dodge Durango service schedule on Cape Cod follows its engine: GT HEMI uses the 5.7L schedule, R/T 392 uses the 6.4L schedule and Hellcat uses the supercharged 6.2L schedule. Their oil grades, capacities and maximum intervals differ. Premier Cape Cod Chrysler Dodge Jeep Ram provides factory-trained service and genuine Mopar parts for those scheduled visits.
Key Numbers
| Service | GT HEMI 5.7L | R/T 392 6.4L / Hellcat 6.2L |
|---|---|---|
| Engine oil and filter | Oil-life indicator; maximum 7,500 miles / 12 months / 350 hours | Oil-life indicator; maximum 6,000 miles / six months |
| Tires and condition checks | Every oil service; sooner with irregular wear | Every oil service; sooner with irregular wear |
| Cabin air filter | Every 12,000 miles | Every 12,000 miles |
| Engine air filter | Every 30,000 miles; inspect sooner in dusty use | Every 24,000 miles; inspect sooner in dusty use |
| Transfer-case fluid | Every 30,000 miles | Every 24,000 miles |
| Spark plugs | 100,000 miles | 60,000 miles |
| Engine coolant | 10 years / 150,000 miles, whichever first | 10 years / 150,000 miles, whichever first |
The mileage and time limits work together. A low-mileage R/T 392 reaches its six-month oil-service limit even when it has not traveled 6,000 miles. The 5.7L oil-life system also accounts for engine use, with a 350-hour ceiling as well as the mileage and calendar limits. The manual lists service within 500 miles after its oil-change message appears.
| Engine | Oil specification | Capacity including filter |
|---|---|---|
| 5.7L HEMI V8 | Mopar SAE 0W-20 full synthetic or SAE 5W-20 meeting MS-6395 | 7 US quarts |
| 6.4L HEMI V8 | API-certified SAE 0W-40 full synthetic meeting MS-12633 | 7 US quarts |
| Supercharged 6.2L HEMI V8 | API-certified SAE 0W-40 full synthetic meeting MS-12633 | 8.3 US quarts |
An oil service changes the oil and filter and includes the manual’s inspection items. Brakes, hoses, joints, tires, cooling-system protection and the exhaust all have a place in that visit. The performance engines share an oil grade, but their capacities differ; the 5.7L has its own grade and manufacturer standard.
For the 5.7L, 30,000-mile services include the engine air filter and transfer-case fluid, with axle-fluid inspection and changes under the manual’s heavy-use conditions. The 60,000-mile point returns those recurring items. Spark plugs are a 100,000-mile item, with the manual identifying their interval as mileage-based rather than calendar-based.
The R/T 392 and Hellcat schedules use a 24,000-mile rhythm for engine air-filter replacement, transfer-case fluid and front/rear axle-fluid service. Their spark plugs are due at 60,000 miles and again at the matching mileage interval. Cabin filters follow the separate 12,000-mile interval on all three V8 schedules.
Coolant reaches its time limit at 10 years even when the vehicle has not accumulated 150,000 miles. The specified coolant is Mopar OAT meeting MS.90032. The supercharged engine includes an intercooler cooling circuit in addition to its engine circuit, adding a separate system to the Hellcat service routine.
Winter road salt and coastal salt air make underbody and brake inspections relevant around Barnstable and Hyannis. The manual’s oil-service brake inspection covers pads, shoes, rotors, drums, hoses and parking-brake operation. A GT HEMI’s standard disc brakes, a Tow n Go chassis and the R/T or Hellcat Brembo systems each receive service matched to their actual hardware.
Frequent short trips, dusty conditions, towing and temperature extremes affect the maintenance schedule. Towing a loaded trailer and stop-and-go summer travel place different demands on the vehicle from a steady highway drive. Oil-life monitoring responds to engine operating conditions, while the calendar limit continues to apply to a Durango that spends more time parked.
Our service department handles oil and filter changes, brakes, tire service, batteries and factory maintenance. Genuine Mopar parts keep the replacement part matched to the Durango’s engine and equipment. The fluid and capability specifications also separate the GT HEMI, R/T 392 and Hellcat families.
The eight-speed automatic, AWD system and engine-specific cooling systems are maintained as separate parts of the vehicle. The manual lists the correct ZF 8 & 9 Speed automatic-transmission fluid and ATF+4 for the transfer case. The axle lubricant specification also distinguishes a rear axle with an electronic limited-slip differential from one without it.
Regular fluid service, air filtration and inspections support the durability of that hardware. A GT HEMI used for frequent towing has different axle-service conditions from a vehicle used only for ordinary road driving. Premier’s service team works from the engine, axle and equipment on your Durango rather than applying one schedule to every model.
The scheduled work differs in three measurable ways: oil capacity, service interval and fuel grade. A 5.7L holds 7 quarts and has the longer maximum oil interval; a Hellcat holds 8.3 quarts and follows the six-month or 6,000-mile ceiling. R/T 392 and Hellcat also require premium gasoline, while the 5.7L recommends 89 octane and accepts 87.
A service estimate reflects the oil, filters, inspection work and parts required for that vehicle. The new-vehicle Basic Limited Warranty runs 3 years or 36,000 miles, and the Powertrain Limited Warranty runs 5 years or 60,000 miles, whichever comes first. Routine maintenance is separate from warranty repair; our team provides the itemized service estimate for the visit.
Our service department at 556 Yarmouth Rd in Hyannis serves drivers near Falmouth, Plymouth, Barnstable and Marion. The service team handles factory maintenance for all three HEMI engine families. Schedule Durango service or call (508) 815-5000 for an appointment.

The 5.7L oil-life indicator calls for service according to operating conditions, with an absolute maximum of 7,500 miles, 12 months or 350 engine hours, whichever comes first. The manual also calls for service within 500 miles of the oil-change message. Frequent short trips and towing influence when the message appears.
The R/T 392 and Hellcat engines must not exceed 6,000 miles or six months between oil changes, whichever comes first. Their oil-life indicators can request service earlier. Both use SAE 0W-40 full synthetic meeting MS-12633, while the 6.2L holds more oil than the 6.4L.
The 5.7L and 6.4L engines each hold 7 US quarts with the oil filter. The supercharged 6.2L holds 8.3 US quarts with the filter. Oil grade is also engine-specific: the 5.7L uses the MS-6395 grade listed in the manual, while the performance engines use 0W-40 meeting MS-12633.
The 2027 manual lists cabin-air-filter replacement every 12,000 miles for the V8 engine schedules. Engine air-filter intervals differ: 30,000 miles for the 5.7L schedule and 24,000 miles for the R/T 392 and Hellcat schedules. Dusty operation adds air-filter inspections at the oil-service visits.
The 5.7L schedule lists spark-plug replacement at 100,000 miles, while the 6.4L and supercharged 6.2L schedules list 60,000 miles. Those spark-plug intervals are mileage-based. The difference is tied to the engine, so GT HEMI Premium follows the 5.7L schedule and R/T 392 Premium follows the 6.4L schedule.
The manual calls for tire rotation at the first sign of irregular wear, even before the oil-change indicator turns on. Tire condition is also part of the oil-service inspection. Brakes, CV and universal joints, cooling-system hoses and the exhaust system receive checks alongside scheduled oil and filter service.
The manual specifies coolant service at 10 years or 150,000 miles, whichever comes first. Its listed coolant is Mopar’s OAT formula meeting MS.90032. The 6.2L Hellcat also has a separate intercooler cooling circuit, so its cooling-system capacities differ from the 5.7L and 6.4L engines.
