Engine oil

The 2024 Ram 1500 lineup uses different oils by engine:

• 3.6L Pentastar V6: SAE 0W-20 meeting FCA MS-6395 (API SP/GF-6A). Capacity about 5.9 quarts with filter.
• 5.7L HEMI V8 (with or without eTorque): SAE 0W-20 meeting FCA MS-6395 (API SP/GF-6A). Capacity about 7.0 quarts with filter.
• 6.2L Supercharged V8 (TRX): SAE 0W-40 meeting FCA MS-12633. Capacity about 7.0 quarts with filter.

Intervals: Follow the oil life monitor; many owners see 6,000–10,000 miles/12 months under normal service. Severe duty (frequent towing, idling, dusty conditions) may require shorter intervals. Always verify exact capacity in the owner’s manual or OEM service info.

Pitfalls: Use oil that explicitly states it meets the FCA spec (MS-6395 or MS-12633 for TRX). Do not substitute heavier grades unless directed by TSBs or the manual. Replace the filter at each change and check for dual-drain systems on some V8 pans.

Engine coolant

Use Mopar 10-Year/150,000-Mile OAT (purple/pink) coolant meeting FCA MS-12106. It’s pre-mixed 50/50 when sold as premix; if using concentrate, mix with distilled water.

Intervals: Factory fill is 10 years/150,000 miles initial, then typically 5 years/100,000 miles thereafter.

Pitfalls: Do not mix OAT (MS-12106, purple) with older HOAT (orange, MS-9769) or “universal” coolants. Mixing can gel and reduce corrosion protection. Thoroughly bleed air via the specified procedure after service.

Automatic transmission fluid (ZF 8-speed)

All 2024 Ram 1500 automatic transmissions are ZF 8-speed variants. Use Mopar 8 & 9 Speed ATF (equivalent to ZF Lifeguard 8). Do not use ATF+4 (MS-9602) in the 8-speed.

Capacities: A drain-and-fill typically returns 5–7 quarts; a dry fill is around 9–10 quarts, varying with the pan/filter design. These units use a temperature-based level set procedure—follow OEM steps and use the correct fill plug.

Intervals: Labeled “filled for life,” but many service them at 60,000–100,000 miles depending on use. Verify by VIN and follow OEM procedures.

Pitfalls: Never mix fluid types. Use the correct pan/filter (steel vs. composite) and torque specs to avoid leaks. Overfilling or underfilling can cause shift issues.

Transfer case fluid (4x4)

Two common transfer cases appear on Ram 1500:

• BW44-44 (on-demand/auto 4WD): Requires Mopar BW44-44 Transfer Case Fluid (p/n 68089195AA or superseding). Do not substitute ATF.
• Part-time 4WD (select models): Some use Mopar ATF+4 meeting FCA MS-9602.

Capacity is typically 1.6–2.0 quarts. Always identify the transfer case by tag or VIN and confirm the specified fluid.

Intervals: Often 60,000 miles under normal service; sooner if deep-water crossings, off-road, or frequent towing.

Pitfalls: Using ATF+4 in a BW44-44 (or vice versa) can damage the case. Clean around plugs before removal to keep grit out.

Front differential (4x4)

Use full-synthetic API GL-5 gear oil. Many Ram 1500 front axles specify SAE 75W-85; some allow 75W-90. Capacity usually 1.1–1.6 quarts depending on axle. Verify by axle code and service info.

Intervals: Typically 60,000 miles severe service; up to 100,000 miles normal use. Replace sooner after water intrusion.

Pitfalls: Do not use GL-4. Ensure proper fill level—overfilling can aerate the oil.

Rear differential (9.25/9.75)

Use full-synthetic API GL-5. Weight depends on axle and towing package:

• Many standard-duty setups: 75W-90.
• Heavy-duty/towing or high-ambient: 75W-140.

If equipped with Trac-Lok limited-slip, add the Mopar friction modifier unless your oil states it already contains LSD additive. Capacity is generally 2.5–3.5 quarts—confirm by axle code.

Intervals: Similar to front—60,000 miles severe service; up to 100,000 miles normal.

Pitfalls: Wrong viscosity or no friction modifier in LSD axles can cause chatter. Torque cover bolts evenly to prevent leaks.

Brake fluid

Use DOT 3 brake fluid (Mopar DOT 3).

Intervals: Brake fluid is hygroscopic; test every 2–3 years and flush when contaminated or by 30,000–45,000 miles in severe climates. About 1–2 quarts is typically needed for a full flush.

Pitfalls: Never mix DOT 5 silicone with DOT 3/4/5.1. Keep fluid off painted surfaces.

Power steering

The 2024 Ram 1500 uses electric power steering (EPS). There is no hydraulic power steering fluid or scheduled service.

Windshield washer fluid

Use a quality washer solvent suitable for your climate (−20°F/−29°C or lower where needed). Capacity is roughly 0.8–1.2 gallons. In freezing climates, avoid plain water.

Diesel Exhaust Fluid (DEF)

Not applicable: The 2024 Ram 1500 is not offered with the EcoDiesel engine. If servicing an earlier EcoDiesel truck, use DEF conforming to ISO 22241.
