A good rule is every 8,000 miles or 6 months, but shorten to about 4,000 miles for severe Tucson heat, dust, frequent towing, or idling.

Follow your owner’s manual and the oil life monitor for the most accurate interval for your 6.4L V8. Arizona’s high temperatures, dusty conditions, and heavy-duty cycles can accelerate oil oxidation and contamination, so severe-duty intervals help safeguard engine longevity. We document every visit to keep your maintenance records complete.

• Normal: ~8,000 miles/6 months; Severe: ~4,000 miles
• Adjust for towing, heavy loads, off-road, or stop-and-go use
• Book early: schedule service

Use full synthetic SAE 0W-40 that meets FCA (MOPAR) specification, as outlined in the 2018 Ram 2500 owner’s manual for the 6.4L V8.

Full synthetic 0W-40 provides strong high-temperature protection for Arizona heat while maintaining cold-start flow. We install OEM-spec oil and a MOPAR-quality filter to preserve performance and warranty compliance. If you haul or tow, staying with the factory-approved viscosity helps stabilize oil pressure and protect bearings under load.

• Viscosity: SAE 0W-40 (full synthetic)
• Meets FCA/MOPAR specification
• OEM-spec filter installed with each change

The 2018 Ram 2500 6.4L V8 typically takes about 7.0 quarts of oil with a filter change.

We fill to spec, start the engine, and re-check the level after filter saturation to confirm the final mark. Using the correct capacity prevents aeration and pressure loss under load, important for towing and long highway grades around Tucson. Your service record will note oil type and quantity for future reference.

• Approximate capacity: 7.0 quarts with filter
• Level verified after warm restart
• Documented on your repair order

Full synthetic offers the best oxidation resistance and high-temp stability, matching the 2018 Ram 2500’s factory specification needs.

Conventional oil protects in mild use but breaks down faster under heat and load. Blends improve stability but still trail full synthetic for towing or desert heat. For the 6.4L V8, full synthetic at the OEM viscosity is the most consistent choice for longevity and performance.

• Conventional: budget, shorter life
• Blend: mid-tier stability
• Full synthetic: highest protection, OEM-aligned
