The 2019 RAM 1500 requires synthetic engine oil, but the exact viscosity depends on which engine you have. Gasoline versions typically use 0W-20 or 5W-20, while the EcoDiesel uses 5W-40. Always verify the precise specification in your owner's manual or on the door‑jamb label.
Engine options and oil recommendations
The RAM 1500 came with three engine choices in 2019. Each engine has its own oil requirements, so it’s important to identify which engine your truck has before purchasing oil.
Gasoline engines (3.6L Pentastar V6 and 5.7L Hemi V8)
Gasoline RAM 1500 engines use synthetic engine oil, with common viscosity recommendations listed below. Confirm exact grade for your vehicle from the manual or label.
- 3.6L Pentastar V6 (gas): 0W-20 synthetic engine oil, API SN/ILSAC GF-5, Mopar-approved.
- 5.7L Hemi V8 (gas): 5W-20 synthetic engine oil, API SN/ILSAC GF-5, Mopar-approved.
Oil grade can vary by climate and model year, so always double-check the spec for your specific truck. Using the specified viscosity helps with cold starts, fuel economy, and engine protection.
In summary, for the RAM 1500’s gasoline engines, synthetic oil in the 0W-20 or 5W-20 range is typical, but you must verify the exact grade for your engine configuration.
Diesel engine (3.0L EcoDiesel)
The EcoDiesel variant uses a different oil specification designed for diesel engines. Use full-synthetic oil that meets the appropriate diesel standard.
- 3.0L EcoDiesel: 5W-40 full-synthetic engine oil, API CK-4 (or equivalent newer specification as approved by Mopar).
Diesel engines require oil formulated for diesel operation and may have stricter emissions-related requirements. Always confirm the correct grade and specification for your EcoDiesel version.
In summary, the RAM 1500’s oil needs vary by engine type. Gasoline models typically use 0W-20 or 5W-20 synthetic oil, while the EcoDiesel uses 5W-40 full-synthetic oil designed for diesel engines. When in doubt, follow the official manual or consult a RAM dealer.
Helpful notes and tips
Always check the owner’s manual or the sticker inside the driver’s door for the exact oil viscosity and specification required for your vehicle. If you’re using an oil change service, tell the technician your engine type and year so they can verify the correct grade. Regular oil changes with the proper oil help maintain fuel economy, emissions compliance, and engine longevity.
Summary
To sum up, a 2019 Dodge RAM 1500 takes synthetic oil, with exact viscosity dependent on engine: 0W-20 or 5W-20 for gasoline engines and 5W-40 for the EcoDiesel. Always verify the precise specification in the owner’s manual or on the door jamb label to ensure you use the correct oil for your specific engine configuration.

What oil should I put in my 2019 Ram 1500?
For the 2019 RAM 1500, the oil type depends on your engine: the 3.6L V6 uses approximately 6 quarts of 0W-20 full synthetic oil, the 5.7L HEMI V8 uses 7 quarts of 5W-20 full synthetic oil, and the 3.0L EcoDiesel (Gen 2) uses approximately 10.5 quarts of 5W-40 full synthetic diesel oil meeting MS-10902/API CJ-4 ...
Is the RAM 1500 0w20 or 5w20?
2019-newer Ram 1500 trucks with the 5.7L HEMI require 0W-20 synthetic oil meeting Chrysler MS-6395 specifications, while 2009-2018 models typically use 5W-20.
What rams to stay away from?
Buyers commonly choose to avoid 2013–2015 and 2018 Ram 1500 models unless maintenance records are excellent, because these years more frequently show repeat transmission and electrical complaints than other model years.
