Understanding the specific lubrication requirements for your 2017 Ram 1500 5.7-liter HEMI V8 is fundamental to ensuring long-term reliability and peak performance. This particular powertrain, known for its robust design and capability, demands the correct oil type and specification to maintain optimal viscosity, lubrication, and protection under various driving conditions. Choosing the wrong fluid can lead to increased friction, reduced fuel economy, and potentially expensive mechanical failures down the road, making this a critical maintenance consideration for any owner.
Manufacturer Specifications and API Standards
Ford Motor Company, the manufacturer of the 2017 Ram 1500 equipped with the 5.7-liter HEMI, provides precise guidelines regarding the approved oil type and performance standards. Owners should always refer to the vehicle's owner manual for the most accurate information, but the general specification points to a high-quality motor oil meeting specific API and ILSAC criteria. The recommended standard is typically API SN or the newer API SP rating, which ensures the oil provides adequate protection against wear, deposit formation, and oxidation. Furthermore, the oil must conform to the ILSAC GF-5 specification, which guarantees fuel economy improvements and compatibility with the engine's emissions control systems.
Viscosity Grade: 5W-20 is Standard
The most critical characteristic of the oil for this engine is its viscosity grade, which dictates how the fluid flows at different temperatures. For the 2017 Ram 1500 5.7 HEMI, the factory-fill and recommended viscosity is 5W-20. This multi-grade oil is engineered to offer the viscosity of a 5-weight oil in cold temperatures and a 20-weight oil when hot. The "5W" ensures excellent cold-start protection, allowing the oil to circulate quickly through the engine components during winter starts, while the "20" provides the right balance of thickness for optimal lubrication and oil pressure at normal operating temperatures. Using a thicker oil, such as 10W-30 or 10W-40, is generally not recommended as it can negatively impact fuel economy and may not provide the intended protection in the variable valve timing system.
Synthetic vs. Conventional Oil Options
When selecting an oil for your 5.7 HEMI, you have the choice between conventional, synthetic blend, and full synthetic formulations. While the engine will run on conventional oil that meets the API SN specifications, upgrading to a synthetic or synthetic blend is often highly beneficial. Full synthetic oils are chemically engineered to provide superior thermal stability, reducing the breakdown of the oil under the high temperatures generated by the HEMI's aluminum engine block. They also offer better protection in extreme cold, improved resistance to oxidation, and enhanced cleaning capabilities to keep the intricate passages of the Multi-Displacement System (MDS) clean. For owners who frequently tow heavy trailers, drive in severe climates, or subject their trucks to stop-and-go traffic, the investment in a premium synthetic oil is strongly advised.
Capacity and the Importance of the MDS
The 2017 Ram 1500 5.7 HEMI has an oil change capacity of approximately 6.4 quarts when paired with the standard oil filter. This capacity is important to know to ensure you add the correct amount of oil during a change, preventing under-filling, which leads to lubrication issues, or over-filling, which can cause increased pressure and potential seal leaks. A critical feature of this engine is the Multi-Displacement System (MDS), a cylinder deactivation technology that shuts off four cylinders during light-load conditions to improve fuel efficiency. This system places specific demands on the oil; it must circulate quickly and reliably to the active cylinders while the deactivated pistons are in a resting position. Using a modern, high-quality oil that meets the GF-5 standard is essential to ensure the MDS operates smoothly, valves open and close correctly, and the system does not suffer from the shuddering or failure that can occur with improper lubrication.
