Engine Oil

The 2017 Ram 1500 offers two engine options, each with a specific oil requirement. The 3.6L Pentastar V6 uses SAE 5W-20 oil meeting Chrysler’s MS-6395 specification. The 5.7L HEMI V8 also calls for SAE 5W-20, MS-6395. It is critical to use the correct viscosity and specification to ensure proper lubrication and protection. Using a non-spec oil can lead to premature wear and damage. Change intervals are best determined by the oil life monitoring system, but a good rule of thumb is every 5,000-7,500 miles.

Engine Coolant

All 2017 Ram 1500s use a Mopar 10-year/150,000-mile OAT (Organic Acid Technology) coolant, meeting specification MS-12106. This is a purple-colored fluid, and it is crucial not to mix it with other coolant types. Mixing HOAT (Hybrid Organic Acid Technology) or IAT (Inorganic Additive Technology) coolants will cause gelling and can lead to cooling system blockage and engine damage. Always top off with the same Mopar OAT coolant or an equivalent that meets the MS-12106 spec. A 50/50 mix with distilled water is recommended.

Transmission Fluid

The 8-speed automatic transmission in the 2017 Ram 1500 requires Mopar ZF 8&9 Speed ATF, which is also compatible with ATF+4. This is a synthetic fluid designed for long service intervals. While some sources claim "lifetime fill," it is wise to perform a fluid and filter change every 60,000-100,000 miles to ensure optimal performance and longevity. Never use a universal or multi-vehicle ATF, as this can cause shifting problems and transmission failure.

Transfer Case Fluid

For 4WD models, the transfer case requires Mopar ATF+4. This is the same fluid used in many Chrysler, Dodge, and Ram transmissions. The service interval is typically every 30,000-60,000 miles, but it is best to consult the owner's manual for the exact recommendation. Failure to change the transfer case fluid can lead to excessive wear and costly repairs.

Differential Fluid

The front differential on 4WD models calls for SAE 75W-90 gear oil. The rear differential, on the other hand, specifies a heavier SAE 75W-140 synthetic gear oil. If the truck is equipped with a limited-slip differential (LSD), a friction modifier additive must be included. Many synthetic gear oils already have this additive, but it is essential to verify. A typical service interval for differential fluid is 30,000-60,000 miles.

Brake Fluid

The 2017 Ram 1500 uses DOT 3 brake fluid. It is important to keep the brake fluid reservoir full and to bleed the system whenever air is introduced. Brake fluid is hygroscopic, meaning it absorbs moisture from the air. For this reason, it is recommended to flush the brake fluid every 2-3 years to prevent corrosion and maintain braking performance.

Power Steering Fluid

The 2017 Ram 1500 is equipped with Electric Power Steering (EPAS) and does not have a traditional hydraulic power steering system. Therefore, no power steering fluid is required.

Washer Fluid

Use a quality all-season washer fluid with a freeze protection rating of at least -30°F to prevent freezing in cold climates. This is a simple but essential fluid for maintaining visibility in all driving conditions.

Diesel Exhaust Fluid (DEF)

For models equipped with the 3.0L EcoDiesel engine, API-certified Diesel Exhaust Fluid (DEF) meeting ISO 22241 is required. The DEF tank has an 8-gallon capacity and will need to be refilled periodically. The truck’s information center will provide a warning when the DEF level is low. It is crucial to use only high-quality DEF to prevent damage to the exhaust aftertreatment system.
