Ram 1500 Oil Capacity & Oil Type
TL;DR
There is no single Ram 1500 oil capacity - it varies by engine code and model year, from about 5.9 qt for the V6 up to 10.5 qt for the early EcoDiesel. Always confirm with your underhood emissions label or owner's manual.
Why there is no one answer for the Ram 1500
The Ram 1500 has been sold with several completely different engines since 2012, and each one has its own oil capacity and viscosity spec. Quoting a single number for the whole nameplate - as some quick-answer sites do - risks giving you the wrong figure, especially since the 3.0L EcoDiesel capacity actually changed between its second and third generations, and the new 3.0L Hurricane replaced both the V6 and part of the V8 lineup for 2025.
Capacity and viscosity by engine
The table below lists figures corroborated by oil-lookup tools and service references for each engine code. Where two credible sources gave slightly different figures, the value is shown as a range.
| Engine code / years | Capacity with filter (L / US qt) | Viscosity |
|---|---|---|
| 3.6L Pentastar V6 (2012-2024) | 5.6-5.7 L / 5.9-6.0 qt | SAE 0W-20 (5W-20 on some older model years) |
| 5.7L HEMI V8, incl. eTorque (2003-2024, 2026) | 6.6 L / 7.0 qt | SAE 0W-20 (5W-20 on pre-2022 model years) |
| 3.0L EcoDiesel V6, 2nd generation (2014-2019) | 9.9 L / 10.5 qt | SAE 5W-40 full synthetic (diesel-rated) |
| 3.0L EcoDiesel V6, 3rd generation (2020-2023) | 8.0 L / 8.5 qt | SAE 5W-40 full synthetic (diesel-rated) |
| 3.0L Hurricane I6 Standard Output (2025-2026) | 7.1 L / 7.5 qt | SAE 0W-20 full synthetic |
| 3.0L Hurricane I6 High Output (2025-2026) | 7.1 L / 7.5 qt | SAE 0W-40 full synthetic |
How to confirm the exact figure for your truck
Because trim, model year, and engine option all interact, the safest approach is to check the specification printed for your own vehicle rather than relying on any online chart, including this one.
- The underhood emissions/VECI sticker usually lists the exact oil viscosity grade.
- The owner's manual for your specific model year gives the exact fill capacity and any top-off procedure.
- A quick-lube shop or dealer can look up the capacity from the VIN, which encodes the exact engine.
Older Ram 1500 engines
Earlier Ram 1500 generations (through about 2012) used the 3.7L V6 and 4.7L V8 engines. Because figures for those engines were not consistently corroborated across sources during this review, they are intentionally omitted here - consult your owner's manual or a dealer parts department if you own one of these older trucks.

Frequently asked questions
Does the 3.6L Pentastar V6 in the Ram 1500 really take less oil than the 5.7L HEMI?
Yes. The 3.6L Pentastar V6 has a smaller displacement and typically takes about 5.9-6.0 US qt (5.6-5.7 L) with a filter, versus about 7.0 US qt (6.6 L) for the 5.7L HEMI V8. Always confirm the figure against your own owner's manual since running the wrong amount can trigger low-oil or overfill warnings.
Why did the EcoDiesel oil capacity change over the years?
The 3.0L EcoDiesel went through a redesign between its second generation (2014-2019, about 10.5 US qt / 9.9 L) and third generation (2020-2023, about 8.5 US qt / 8.0 L). The two versions share a displacement but not an oil pan or filter housing, so they are not interchangeable specs - check your VIN or engine code before topping off.
What oil does the new 3.0L Hurricane engine need?
The 3.0L Hurricane inline-six introduced for 2025 comes in a Standard Output tune calling for SAE 0W-20 and a High Output (twin-turbo) tune calling for SAE 0W-40, with both variants holding roughly 7.5 US qt (7.1 L) with a new filter. Using the wrong viscosity between the two tunes is not recommended by the factory spec.
Where is the most reliable place to check my exact Ram 1500 oil capacity?
Your own truck's underhood emissions sticker (VECI label) and owner's manual are the authoritative sources, because they are matched to your exact engine and model year via the VIN. Generic online charts, including this page, are a good starting point but can lag behind spec updates or mid-year running changes.
