While the 5W-20 viscosity remains correct, choosing a high-quality oil with a robust additive package designed for heavy-duty service is essential. A superior filter will have a higher dirt-holding capacity and a robust anti-drainback valve, which keeps oil in the engine during startup for instant protection.

The "20" denotes the high-temperature viscosity, providing the necessary thickness to maintain a robust oil film under the high pressures and temperatures generated by the HEMI's performance. Viscosity: The Lifeblood of Engine Protection Viscosity, measured in numbers such as 5W-20 or 10W-30, refers to the oil's resistance to flow and is the most critical factor in the Ram 1500 5.
Full synthetic oil offers superior thermal stability, meaning it breaks down less under the intense heat of the HEMI. Look for products specifically marketed for towing or those that exceed the API SP standard, as they often provide enhanced protection against oxidation and sludge buildup, ensuring the engine remains reliable under pressure.
