The 2019 Ram 1500 DT represents a complete redesign with two available powertrains—each requiring tailored maintenance. Whether you own the 3.6L Pentastar V6 or the 5.7L HEMI V8 (both offered with or without the eTorque mild-hybrid system), following Ram's factory intervals is critical to preserving the 8-speed automatic transmission and preventing costly repairs on this modern, technology-laden truck.
Service Intervals
| Service | Interval | Est. Cost |
|---|---|---|
| Engine Oil & Filter3.6L V6 and 5.7L HEMI use 0W-20 full synthetic oil; interval may be shorter under severe duty (towing, extreme temps) per oil-life monitor. | 10,000 mi / 12 mo | $60-$120 |
| Tire RotationRam specifies 8,000-mile rotation to prevent uneven wear on the DT's larger wheel/tire packages and maintain traction control effectiveness. | 8,000 mi | $25-$50 |
| Cabin Air FilterReplaceable element behind glove box; more frequent changes needed in dusty or high-pollen environments. | 20,000 mi / 24 mo | $20-$45 |
| Engine Air FilterInspect at every oil change; replace at 30k miles or sooner if operating in dusty conditions or towing frequently. | 30,000 mi | $25-$55 |
| Brake Fluid FlushDOT 3 fluid absorbs moisture over time; 3-year flush prevents internal corrosion in the ABS module and calipers. | 36 mo | $80-$140 |
| Brake Pads & Rotor InspectionInspect every 25k miles; replacement typically needed at 40k-60k miles depending on towing habits and brake use. | 25,000 mi | $300-$600 |
| 8-Speed Automatic Transmission FluidRam officially lists this as 'lifetime fill,' but independent mechanics and heavy-duty users recommend a 60k-mile drain-and-fill to prevent valve body issues. | 60,000 mi | $250-$400 |
| Coolant Flush (OAT)Factory OAT coolant (Organic Acid Technology) is rated for 10 years/100k miles; protects aluminum engine components from corrosion. | 100,000 mi / 120 mo | $120-$200 |
| Spark PlugsIridium plugs in both the 3.6L Pentastar and 5.7L HEMI are rated for up to 100k miles under normal use. | 100,000 mi | $180-$350 |
| Differential Fluid (Rear/Front if 4WD)Rear differential every 50k miles; front differential (4WD models) at same interval; critical for trucks used for towing or off-road. | 50,000 mi | $100-$180 |
| Transfer Case Fluid (4WD only)Applies to part-time and full-time 4WD systems; neglect can cause chain wear and expensive transfer case failure. | 60,000 mi | $90-$150 |
| Battery Inspection & TestAGM battery standard on many trims; test every 3 years as the DT's electronics and start-stop system place heavy demands on the battery. | 36 mo | $150-$250 |
2019 Ram 1500 Oil Change Interval
The 2019 Ram 1500 oil change interval is every 10,000 miles or 12 months, whichever comes first (estimated cost $60-$120). 3.6L V6 and 5.7L HEMI use 0W-20 full synthetic oil; interval may be shorter under severe duty (towing, extreme temps) per oil-life monitor.
What Happens If You Skip It
- Skipping 8-speed transmission fluid changes can lead to harsh shifting, valve body failure, and $3,500+ transmission replacement—a known weak point in high-mileage DT trucks.
- Neglecting differential fluid on towing-equipped Rams accelerates gear wear and can cause catastrophic rear-end failure, especially in limited-slip differentials.
- Delaying brake fluid flushes causes internal corrosion in the ABS module, leading to expensive electronic brake system repairs common after 5+ years.
- Skipping cabin air filter replacement reduces HVAC efficiency and can allow debris into the blower motor, a $400+ repair on this generation.
Common Issues at Higher Mileage — 2019 Ram 1500
8-speed transmission shudder or delayed shifts, often resolved with fluid change or software update; valve body replacement needed in severe cases.
HEMI 5.7L lifter tick or 'Hemi tick' due to MDS (cylinder deactivation) system; may require lifter and camshaft replacement if severe.
Rear differential pinion seal leaks on trucks used for towing, leading to fluid loss and potential gear damage if not addressed.
Uconnect infotainment system freezing or touchscreen failure; software updates sometimes resolve, but screen replacement may be required.
Front suspension ball joint and control arm bushing wear, especially on 4WD models, causing clunking noises and alignment issues.
FAQ
How often does a 2019 Ram 1500 need an oil change?
The 2019 Ram 1500 oil change interval is every 10,000 miles or 12 months, whichever comes first (estimated cost $60-$120). 3.6L V6 and 5.7L HEMI use 0W-20 full synthetic oil; interval may be shorter under severe duty (towing, extreme temps) per oil-life monitor.
