What type of oil for 2018 Dodge Durango?
The Durango uses synthetic motor oil, and the exact viscosity depends on the engine: 0W-20 for the 3.6L V6, 5W-20 for the 5.7L Hemi, and 5W-40 for the 6.4L Hemi (SRT).
Engine-specific oil recommendations
The 2018 Durango offered three engines. The official viscosity guidance is to use full-synthetic oil that meets FCA MS-6395, API SN or better. Here are the engine-specific specs:
- 3.6L Pentastar V6 — 0W-20 synthetic motor oil; meets FCA MS-6395 specification; API SN or newer.
- 5.7L Hemi V8 — 5W-20 synthetic motor oil; meets FCA MS-6395 specification; API SN or newer.
- 6.4L Hemi (SRT) — 5W-40 synthetic motor oil; meets FCA MS-6395 specification; API SN or newer.
Note: If you’re unsure which engine your Durango has, check the under-hood label or the owner’s manual for the exact spec, and ensure the oil you buy is full synthetic and meets the correct specification.
Maintenance and oil-change intervals
To maximize engine life, follow the factory-recommended intervals and use the vehicle’s oil-life monitor. The guidelines below align with typical factory recommendations and what many owners observe in practice:
- Normal driving with 0W-20 or 5W-20 synthetic oil: oil changes are commonly advised around 5,000–7,500 miles, or as indicated by the oil-life monitor.
- Severe driving conditions (towing, frequent short trips, extreme temperatures): changes may be needed more often, roughly 3,000–5,000 miles.
- Always reset the oil-life monitor after a change and use a Mopar-approved filter to maintain warranty coverage and optimal filtration.
In practice, the vehicle’s oil-life monitor provides the most accurate interval for your specific Durango and engine configuration.
Summary
The 2018 Dodge Durango requires synthetic motor oil with engine-specific viscosities: 0W-20 for the 3.6L V6, 5W-20 for the 5.7L Hemi, and 5W-40 for the 6.4L Hemi SRT. Use oil that meets FCA MS-6395 and API SN or newer, and follow the oil-life monitor for changes. Regular, correctly specified oil changes help ensure long-term performance and reliability.
