Tuscaloosa Chrysler Dodge Jeep Ram
The 2027 Ram 2500 6.4L gas engine requires oil changes no later than every 8,000 miles; the 6.7L diesel requires them every 15,000 miles. Interval and task requirements differ significantly between the two engines, so using the correct schedule for your powertrain matters. This page covers key service intervals, warranty terms, and general ownership information, view 2027 Ram 2500 inventory at Tuscaloosa CDJR or contact our service team for specifics on your truck.
The 2027 Ram 2500 is available with two distinct powertrains, each carrying its own published maintenance schedule. The 6.4L gas engine and the 6.7L Cummins Turbo Diesel have different service intervals, fluid types, and inspection tasks. Use the section that matches your engine. For the full interval-by-interval task list for your specific trim and configuration, contact the Tuscaloosa CDJR service team.
The 6.4L gas engine uses an oil change indicator system that monitors driving conditions and alerts you when service is due by displaying "Oil Change Due" in the instrument cluster. The system is duty-cycle based, meaning the interval can vary depending on how the truck is driven.
Regardless of whether the indicator has triggered, oil and filter must be changed no later than every 8,000 miles (13,000 km), 12 months, or 350 hours of engine run time, whichever comes first. The 350-hour threshold is primarily relevant for fleet customers. Severe service conditions, including high ambient temperatures, short trips, heavy loading, trailer towing, off-road use, or law enforcement duty, can reduce this interval further.
Scheduled service milestones for the 6.4L engine occur every 10,000 miles from 20,000 through 150,000 miles. Each service visit includes oil and filter change, tire rotation, CV/Universal joint inspection, front suspension and tie rod inspection, axle surface inspection, brake lining inspection, parking brake check, and transfer case fluid inspection.
Additional maintenance items such as cabin air filter replacement, engine air cleaner filter replacement, spark plugs, engine coolant flush, and PCV valve inspection occur at longer specified intervals within that 150,000-mile schedule.
For the exact mileage at which each additional task is due on your truck, contact Tuscaloosa CDJR or schedule a service appointment and our technicians can walk through your specific vehicle's requirements.
The 6.7L Cummins Turbo Diesel carries a different service cadence. Engine oil must be changed every 15,000 miles (24,000 km), 12 months, or 500 hours, whichever comes first, or sooner if prompted by the oil change indicator system. The Cummins Turbo Diesel does not require a traditional break-in period, but following a few early-operation recommendations, such as warming the engine before placing it under load and varying throttle at highway speeds when carrying weight, supports long-term durability.
Scheduled service milestones for the 6.7L diesel run every 7,500 miles from 7,500 through 150,000 miles. Each service visit includes oil and filter change, Diesel Exhaust Fluid (DEF) tank check and refill as needed, tire rotation, front end lubrication where applicable, engine air cleaner filter inspection, CV/Universal joint inspection, front suspension and tie rod inspection, brake lining inspection, parking brake check, drive belt inspection, and wheel bearing inspection.
The engine air cleaner filter must be replaced before it reaches 30,000 miles (48,000 km) or 24 months, whichever comes first.
Additional maintenance items, including front and rear engine fuel filters, axle fluid service, transfer case fluid, automatic transmission fluid, Crankcase Ventilation (CCV) filter, power steering fluid, and engine coolant flush, occur at longer specified intervals within the 150,000-mile schedule. Ram recommends that all cooling system service on the diesel be performed by an authorized dealer.
For the exact mileage at which each task is due, contact Tuscaloosa CDJR. Our service team can pull your vehicle's requirements and answer questions specific to how you use the truck.
Regardless of engine type, a few checks should be performed monthly or before any long trip:
These checks take a few minutes and help catch developing issues before they become roadside problems. If you notice anything outside of normal ranges, contact Tuscaloosa CDJR to schedule an inspection.
Specific labor or parts prices are not listed here because service costs vary based on trim, configuration, options, and regional labor rates. What matters most is knowing what each visit covers so you can plan accordingly.
The oil change requires the correct fluid specification for your engine. The 6.4L HEMI V8 carries a larger oil capacity than most light-duty trucks, and uses synthetic oil matched to its specifications. The 6.7L Cummins Turbo Diesel has specific fluid requirements, including DEF top-off at each service visit.
Tire rotation on a heavy-duty truck carries real consequences if skipped. The Ram 2500 handles significant payload and towing loads depending on configuration. Uneven wear under those loads accelerates quickly, and consistent rotation protects both tire life and handling balance.
Brake inspection at each service visit is especially relevant for owners who tow regularly. The Ram 2500 uses four-wheel disc antilock brakes across all trims. The available Automatic Smart Exhaust Brake on diesel models helps slow heavy loads, but friction brakes still take substantial heat and mechanical stress during trailer stops. Early detection of pad or rotor wear saves meaningful money compared to deferred repairs.
Battery inspections catch corrosion and loose connections before they cause a problem. This is particularly relevant in Tuscaloosa's humid climate, where terminal corrosion builds faster than in dry regions.

The 2027 Ram 2500 carries a 3-year / 36,000-mile Basic Limited Warranty.
Powertrain coverage differs by engine. Gasoline-powered Ram 2500 models carry a 5-year / 60,000-mile Powertrain Limited Warranty, while diesel-powered Ram 2500 models carry a 5-year / 100,000-mile Powertrain Limited Warranty.
The Corrosion Limited Warranty covers all panels for 3 years / unlimited miles and outer panels for 5 years / unlimited miles.
The Ram 2500 platform has a track record of high-mileage durability, particularly with the 6.7L Cummins diesel. Diesel-equipped trucks that receive consistent oil changes and fluid maintenance routinely accumulate 200,000 or more miles in commercial and farm applications. The 6.4L HEMI V8 carries a similar longevity record when maintained on schedule. The key variable is following the oil change indicator and completing the inspection items bundled with each service visit.
Yes, completely. The 2027 Ram 2500 uses full synthetic oil and an intelligent monitoring system. The old 3,000-mile interval was designed for conventional oil in a different era. Following the indicator, with the 8,000-mile / 12-month ceiling for gas or the 15,000-mile / 12-month ceiling for diesel as a hard backstop, is the correct approach for this truck.
Ignoring the indicator allows degraded oil to remain in the engine, which accelerates wear on cylinder walls, bearings, and turbocharger components on diesel models. The mileage ceiling exists because even a monitoring system has limits under extended neglect. Exceeding that ceiling voids the rationale behind your warranty maintenance obligations.
Diesel maintenance is different, not necessarily harder. Diesel models require DEF fluid top-offs, have specific fuel filter intervals, and carry different fluid specifications than the gas engine. The diesel powertrain carries a 5-year / 100,000-mile Powertrain Limited Warranty. Contact Tuscaloosa CDJR if you have questions about diesel-specific service requirements for your configuration.
You can, but using a Ram-certified service center with OEM Mopar parts protects your warranty coverage and ensures technicians are trained on the specific architecture of the 6.4L HEMI and 6.7L Cummins. For trucks used in commercial and agricultural work, maintaining documented service history at a certified dealer also protects resale value.
The Ram 2500 is a purpose-built work truck, and the Tuscaloosa CDJR service team works on Ram 2500 trucks across the full trim range, from Tradesman work trucks to Limited and Laramie Mega Cab configurations. Our technicians understand the differences in service requirements between gas and diesel powertrains and use OEM Mopar parts on every job.
Using OEM parts keeps every component within the tolerances Ram engineered into the truck. That matters more on a vehicle rated for heavy towing and payload than it does on a typical passenger car. A brake pad that is slightly undersized or a filter that does not seat precisely creates real risk under load.
Our team also maintains your service records in a format that supports warranty claims and simplifies future trade-in or resale documentation. For fleet and commercial buyers in the Tuscaloosa area operating multiple Ram 2500 trucks, that documentation consistency is a practical operational benefit.
