RAM 1500 Oil Type and Capacity Guide (2011-2026)

The 2020 RAM 1500 with the 5.7L HEMI engine requires 5W-20 full synthetic oil with a capacity of 7 quarts (including the oil filter). RAM recommends any API-certified synthetic oil meeting MS-6395 specifications, such as Pennzoil Platinum Full Synthetic or Mopar-branded oil.

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 specifications.

The 2022 RAM 1500 oil capacity varies by engine: approximately 6 quarts for the 3.6L V6, 7 quarts for the 5.7L HEMI V8 (using 0W-20 full synthetic), and approximately 8.5 quarts for the 3.0L EcoDiesel Gen 3 (if equipped). Always verify your specific engine type before adding oil.

The 5.7L HEMI engine in RAM 1500 trucks (model years 2011-2024, and 2026) requires 7 quarts of oil with the filter. For 2022 and newer HEMI-equipped trucks, RAM specifies 0W-20 full synthetic oil; 2013-2021 models use 5W-20 full synthetic. Note that the HEMI was not available in the 2025 model year but returned for 2026. Always confirm the required viscosity on your oil fill cap or in your owner’s manual.

The 2025-2026 RAM 1500 with the 3.0L Hurricane engine has specific oil requirements depending on the version: the Standard Output (SST) uses 7.5 quarts of 0W-20 full synthetic oil meeting API SP and MS-6395 specifications, while the High Output (SST HO / RHO) uses 7.5 quarts of 0W-40 full synthetic oil meeting API SP and MS-A0921 specifications. These are different oil specs — do not substitute 0W-20 in an HO engine. RAM recommends any API SP-certified oil meeting the applicable specification, such as Pennzoil Platinum or Mopar-branded oil.

For most RAM 1500 models, you should use only the viscosity specified in your owner’s manual. For 2013-2021 HEMI-equipped trucks, the spec is 5W-20. For 2022 and newer HEMI trucks, RAM specifies 0W-20. For the 3.6L Pentastar (2019+), the spec is 0W-20. Using an unapproved viscosity—especially with the MDS (cylinder deactivation) system active—can trigger warning lights, affect MDS operation, and potentially impact your warranty. Always follow your owner’s manual for the most accurate guidance.

The 2015 RAM 1500 with the 3.0L V6 EcoDiesel (Gen 2) engine requires approximately 10.5 quarts of 5W-40 full synthetic diesel oil meeting MS-10902 and API CJ-4 specifications. Note that a 2016 TSB (18-078-16) retroactively updated the oil spec for all 2014-2016 EcoDiesels from the original 5W-30 to 5W-40, so if your truck was built before June 30, 2016, confirm you’re using 5W-40. The EcoDiesel was discontinued after the 2023 model year.

RAM strongly recommends full synthetic oil for all 2013 and newer RAM 1500 models. Synthetic oil provides superior engine protection, better performance in extreme temperatures, and longer intervals between oil changes. For 2011-2012 models, either conventional or synthetic 5W-20 is acceptable, though synthetic is still preferred for optimal engine longevity.

To check your oil level, park on level ground, turn off the engine, and wait 5-10 minutes. Pull out the dipstick, wipe it clean, reinsert it fully, then pull it out again. The oil level should be between the MIN and MAX marks. If it’s below the MIN mark, add oil as needed using the correct specification for your engine.

Using the incorrect oil viscosity or type can lead to reduced fuel economy, increased engine wear, poor performance in extreme temperatures, and potential engine damage over time. This is especially critical for Hurricane and EcoDiesel engines, which require specific oil formulations — using Gen 2 EcoDiesel oil in a Gen 3 engine (or vice versa) can cause turbocharger deposits and serious damage. Always use the manufacturer-recommended oil specifications for your specific engine and model year.

No. Oil requirements vary significantly based on engine type and model year. The 3.6L V6 Pentastar uses approximately 6 quarts (5W-20 for 2012-2018, 0W-20 for 2019+). The 5.7L HEMI uses 7 quarts (5W-20 for 2013-2021, 0W-20 for 2022+). The 3.0L EcoDiesel uses approximately 10.5 quarts (Gen 2, 2014-2019) or 8.5 quarts (Gen 3, 2020-2023) of 5W-40 diesel-specific oil, with different spec codes between generations. The 3.0L Hurricane engines use 7.5 quarts of either 0W-20 (Standard Output) or 0W-40 (High Output). Using the wrong oil can cause serious engine problems.

While experienced DIYers can change their own oil, professional service at Fontana Chrysler Dodge Jeep RAM ensures proper disposal of old oil, use of genuine Mopar filters and approved oils, multi-point inspection during service, and maintenance records that preserve your vehicle’s resale value and warranty coverage. For 2026 models with the new 10-year/100,000-mile powertrain warranty, dealer service records are especially important.

RAM recommends any API-certified synthetic oil meeting the material standard for your engine — MS-6395 for most gasoline engines, MS-A0921 for the Hurricane HO, and MS-12991 for the Gen 3 EcoDiesel. Pennzoil Platinum and Shell Helix are specifically named in many RAM owner’s manuals as approved options, and Mopar-branded oil is formulated to meet all manufacturer requirements. Any oil meeting the correct specification from a reputable brand is acceptable.
