Selecting the correct 2017 Dodge Ram oil type is fundamental to ensuring the longevity and peak performance of your full-size pickup. The 5.7-liter HEMI V8 and available 6.4-liter HEMI V8 engines demand specific formulations to handle the substantial power and torque these units deliver on a daily basis.
Manufacturer Specifications and Recommendations
For the standard 5.7-liter HEMI engine found in the 2017 model year, Dodge explicitly recommends using 5W-20 viscosity oil. This specific grade is engineered to provide optimal fuel economy and cold-start protection while maintaining adequate lubrication under normal operating temperatures. Utilizing the correct weight is critical for ensuring the variable valve timing mechanisms function correctly and for preventing unnecessary wear on hydraulic lifters.
Heavy-Duty Towing and Higher-Performance Engines
If your 2017 Dodge Ram is equipped with the 6.4-liter HEMI V8, which produces 410 horsepower and 429 lb-ft of torque, the specifications shift slightly to accommodate the increased thermal stress. While 5W-20 is often acceptable, many fleet managers and performance enthusiasts prefer the stability of 5W-30 or 10W-30 for consistent protection during prolonged heavy towing or hauling duties. For the top-tier 6.7-liter Cummins diesel variant, the requirements change significantly, necessitating CK-4 or FA-4 rated oils specifically designed to manage the higher compression ratios and soot loads inherent in diesel combustion.
Viscosity Grades and Blends
Understanding viscosity is the key to decoding which 2017 Dodge Ram oil type is right for your driving habits. The "W" in 5W-20 stands for winter, indicating the oil's flow characteristics at low temperatures; the number following the "W" represents high-temperature viscosity. A 5W-20 is a multi-viscosity oil that flows like a 5-weight in cold weather and acts like a 20-weight when hot, striking a balance between protection and efficiency that suits most daily drivers.
Mineral Oil: Suitable for casual driving and standard daily commutes, offering basic protection at a lower price point.
Synthetic Blend: A popular compromise for the 2017 Ram, providing better oxidation resistance and performance in extreme temperatures than mineral oil.
Full Synthetic: The ideal choice for vehicles subjected to extreme heat, frequent towing, or stop-and-go traffic, offering superior lubricity and longevity.
API Service Ratings and Additives
Regardless of the viscosity you choose, ensuring the oil meets the current API (American Petroleum Institute) service ratings is non-negotiable. For gasoline engines in the 2017 Ram, you should look for the API SP rating on the container. This designation confirms the oil has been formulated to prevent low-speed pre-ignition (LSPI), a damaging condition common in turbocharged and direct-injection engines, and offers enhanced protection against sludge buildup.
The Role of OEM Certification
Beyond the API rating, verifying Dodge's own certification is crucial for warranty compliance. Look for the dexos1 specification label on the packaging, which indicates the oil has passed General Motors' rigorous standards for detergency and engine cleanliness. Using a certified product helps maintain the integrity of the emissions system and ensures the vehicle continues to meet stringent environmental regulations.
