2019 Ram 1500 5.7 Oil Capacity: HEMI & eTorque Complete Guide 2026

The 2019 Ram 1500 5.7 oil capacity is 7.0 quarts (6.6 liters) with a filter change — but here’s the critical detail most guides miss: the standard 5.7 HEMI requires SAE 5W-20 (Chrysler MS-6395), while the 5.7 HEMI eTorque mild-hybrid demands SAE 0W-20 (Chrysler MS-12991).

Using the wrong viscosity in an eTorque engine can impair the 48V belt-integrated starter-generator and compromise the Multi-Displacement System (MDS). This guide covers both variants on the all-new 2019 DT platform — a complete generational redesign from the 2013–2018 DS platform.

2019 Ram 1500 5.7 HEMI Oil Capacity at a Glance

⚠️ Critical Note: The 2019 Ram 1500 introduced the all-new DT platform, replacing the DS platform used from 2009–2018. The DT platform also swapped the 65RFE 6-speed automatic for the ZF 8HP75 8-speed transmission, improving both efficiency and towing refinement.

Standard 5.7 HEMI vs. eTorque: Why the Oil Viscosity Differs

The eTorque system pairs the 5.7 HEMI with a 48-volt belt-integrated starter-generator (BSG) and a small lithium-ion battery pack. The BSG harvests regenerative braking energy and provides up to 90 lb-ft of supplemental torque during acceleration. Because the BSG interacts directly with the crankshaft via the serpentine belt, Chrysler engineers determined that 0W-20 oil delivers better cold-start lubrication for the integrated system — critical for reducing wear during the milliseconds before full oil pressure builds.

Using 5W-20 in an eTorque engine won’t cause immediate damage, but it falls outside Chrysler MS-12991 spec and may void powertrain warranty coverage. Always check your door jamb sticker or owner’s manual to confirm which variant you have. Learn more about HEMI eTorque vs standard HEMI differences and Ram eTorque specs in our dedicated guides.

Multi-Displacement System (MDS) and Oil Viscosity

The 5.7 HEMI’s MDS deactivates four cylinders under light loads, cutting fuel consumption by up to 20%. This system relies on hydraulic pressure from the engine oil to actuate cylinder deactivation solenoids. Using oil that’s too thick (e.g., 10W-30) slows hydraulic response, while oil that’s too thin may not maintain adequate pressure. Sticking to the specified viscosity — 5W-20 for standard, 0W-20 for eTorque — keeps MDS operating correctly. If you’re experiencing lifter noise, see our guide on Ram 1500 ticking noise at idle.

Recommended Engine Oils for the 2019 Ram 1500 5.7 HEMI

Standard 5.7 HEMI (SAE 5W-20, MS-6395)

5.7 HEMI eTorque (SAE 0W-20, MS-12991)

Always look for the API donut certification and Chrysler MS approval on the bottle. Full synthetic oils are strongly recommended for the eTorque system given the higher thermal demands of the 48V BSG integration. If you’ve been experiencing Ram eTorque problems, incorrect oil viscosity is one of the first things to check.

Oil Filter for the 2019 Ram 1500 5.7 HEMI

Both the standard and eTorque 5.7 HEMI use the same oil filter. The OEM Mopar filter is part number MO-339 (68191349AA) and features a built-in anti-drain back valve (ADBV) that keeps oil in the filter galleries during shutdown, enabling instant lubrication on restart. This is especially important for the eTorque system, which can auto-start the engine dozens of times per trip.

How to Change the Oil on a 2019 Ram 1500 5.7 HEMI

The 2019 DT Ram 1500 sits lower than its DS predecessor, so ramps or a floor jack with jack stands may be needed for drain plug access. Here’s the full procedure:

Tools and Materials Needed

• 7.0 quarts of the correct oil (5W-20 or 0W-20 depending on variant)
• Mopar MO-339 or equivalent oil filter
• 15mm drain plug socket
• Oil filter wrench
• Drain pan (8-quart minimum)
• Jack stands or drive-on ramps
• Torque wrench
• Fresh drain plug gasket (or new drain plug)

Step-by-Step Oil Change Procedure

1. Warm the engine for 5 minutes — warm oil drains faster and carries more contaminants.
2. Lift and secure the truck using ramps or a floor jack with jack stands under the frame rails.
3. Locate the drain plug on the passenger-side rear of the oil pan.
4. Remove the drain plug with a 15mm socket. Allow oil to drain completely (5–10 minutes).
5. Remove the oil filter — it’s located on the passenger side of the engine block.
6. Install the new filter — hand-tighten until the gasket contacts, then tighten 3/4 turn more.
7. Reinstall the drain plug with a new gasket and torque to 20 ft-lbs.
8. Add oil — pour 6.5 quarts, start the engine, check for leaks, then check the dipstick and top up to the full mark (typically 7.0 quarts total).
9. Reset the oil life monitor — hold the OK button on the instrument cluster until the message resets.

2019 Ram 1500 Engine Options Overview

The 2019 DT platform launched with three engine options. The EcoDiesel did not return for the DT platform until 2020.

Note: The 3.0L EcoDiesel was not available for the 2019 DT-generation Ram 1500. It returned as an option for the 2020 model year.

Oil Change Intervals for the 2019 Ram 1500 5.7 HEMI

The 2019 Ram 1500 uses an Intelligent Oil-Life Monitor that adjusts intervals based on driving conditions. As a general guideline:

If you use your 2019 Ram 1500 for towing, check our 2019 Ram 1500 towing capacity guide to ensure you’re operating within SAE J2807-certified limits and factor in more frequent oil changes under heavy tow loads.

DT Platform Changes That Affect Maintenance

The 2019 DT Ram 1500 introduced several changes compared to the 2013–2018 DS platform that affect maintenance procedures:

• ZF 8HP75 8-speed transmission replaced the 65RFE 6-speed — different fluid type and drain plug location. See our guide on the 2019 Ram 1500 transmission dipstick location.
• Lower ride height on the coil-spring rear (vs. leaf-spring on DS trucks in some configurations) — may require ramps for comfortable oil drain access.
• Coil-spring rear suspension on all variants for improved ride quality.
• New front fascia and underbody panels — slightly different jack point locations vs. DS trucks.

Frequently Asked Questions

How many quarts of oil does a 2019 Ram 1500 5.7 take?

The 2019 Ram 1500 5.7 HEMI takes 7.0 quarts (6.6 liters) with a filter change, or 6.5 quarts without replacing the filter.

What oil does a 2019 Ram 1500 5.7 HEMI take?

The standard 5.7 HEMI takes SAE 5W-20 meeting Chrysler MS-6395. The 5.7 HEMI eTorque requires SAE 0W-20 meeting Chrysler MS-12991. Check your door jamb sticker to confirm your variant.

Can I use 5W-30 in my 2019 Ram 1500 5.7 HEMI?

No. Chrysler specifies 5W-20 (or 0W-20 for eTorque) for the 5.7 HEMI. Using 5W-30 may impair MDS cylinder deactivation hydraulics and is outside the certified spec. Stick to the recommended viscosity to maintain warranty coverage and optimal MDS function.

Does the 2019 Ram 1500 have the EcoDiesel?

No. The 3.0L EcoDiesel was not offered in the 2019 DT-generation Ram 1500. It returned as an available engine for the 2020 model year.

What is the oil drain plug torque spec for the 2019 Ram 1500?

The drain plug torque spec for the 2019 Ram 1500 5.7 HEMI is 20 ft-lbs (27 N·m). Always use a new crush washer or drain plug with each oil change to prevent leaks.

Final Thoughts

The 2019 Ram 1500 5.7 HEMI oil capacity is 7.0 quarts regardless of whether you have the standard engine or the eTorque variant — but the viscosity requirement is critically different. Standard 5.7 HEMI owners need SAE 5W-20 (MS-6395); eTorque owners must use SAE 0W-20 (MS-12991). Getting this right protects the MDS, the BSG integration, and your powertrain warranty. Always use a quality filter with an anti-drain back valve, reset your oil life monitor after each change, and consult the Intelligent Oil-Life Monitor rather than a fixed mileage interval for the most accurate service timing.
