Understanding 2017 RAM oil type specifications is essential for maintaining the peak performance and longevity of your heavy-duty truck. The 2017 model year represented a significant period for the RAM lineup, offering a range of powerful engines that demanded specific lubricants to handle high torque and varying operating conditions. Selecting the correct viscosity and certification ensures optimal fuel economy, prevents premature wear, and protects the complex valvetrains found in modern Hemi and Cummins engines.
Decoding the 2017 RAM Engine Lineup
The 2017 RAM trucks were available with several distinct powertrains, each with unique oil requirements. Consumers could choose from the legendary 5.7-liter HEMI V8, the robust 6.4-liter HEMI V8, or the available 6.7-liter Cummins Turbo Diesel. The gasoline engines relied on specific oil standards to manage the high cylinder pressures of the Hemi design, while the diesel engine required formulations tailored for the high compression and soot management needs of the Cummins powertrain.
Recommended Viscosity for Standard Conditions
For the majority of 2017 RAM gasoline models equipped with the 5.7L or 6.4L HEMI, the manufacturer strongly recommended 5W-20 viscosity. This specific grade provided the ideal balance between cold-start protection and high-temperature stability. The "5W" ensures the oil flows freely in freezing temperatures for easy starts, while the "20" maintains a durable film strength at the higher under-hood temperatures generated during towing or hauling heavy payloads.
Cold Weather Performance
Drivers in regions experiencing harsh winters often questioned whether a thinner oil was sufficient. The 5W-20 designation is specifically engineered for sub-zero performance, reducing the friction coefficient when the engine is started cold. This reduces wear on critical components like the timing chain and valvetrain during the most stressful moments of the engine cycle, which is a common concern for RAM owners in colder climates.
Heavy-Duty and Towing Specifications
When the 2017 RAM was subjected to severe service conditions, such as constant towing or hauling in stop-and-go traffic, the oil requirements changed. Under these circumstances, upgrading to a 0W-40 viscosity was often recommended by RAM dealerships. This thicker oil provides enhanced oil pressure and superior film strength, which is vital for protecting the bearings and gears when the engine is operating at higher temperatures for extended periods.
API Certification and Additive Packs
Regardless of the viscosity chosen, the oil must meet specific API certifications to ensure compatibility with the emissions controls and turbochargers found on 2017 models. For the gasoline engines, look for oil that meets the API SP standard and is licensed by ILSAC GF-5. The Cummins diesel engines, however, required meeting the API CK-4 standard, which offers superior protection against sulfated ash that can build up in the DPF (Diesel Particulate Filter) system.
