They use "Hemi oil."
Flush and fill your engine with full synthetic oil with new premium filter. The weight is shown on the oil cap or radiator brace.
Typically the weight is 5W20 if you have MDS
Go to page 677 of the owners manual for oil information specific to your vehicle. I have pasted info from the 2014 manual:
Engine Oil Viscosity – 3.6L/5.7L Engines (1500
Models Only)
MOPAR SAE 5W-20 engine oil or equivalent Pennzoil®
or Shell Helix® is recommended for all operating temperatures. This engine oil improves low temperature
starting and vehicle fuel economy.
The engine oil filler cap also shows the recommended
engine oil viscosity for your vehicle. For information on
engine oil filler cap location, refer to “Engine Compartment” in “Maintaining Your Vehicle” for further information.
NOTE:SAE 5W-30 engine oil approved to Fiat
9.55535-S1 or Fiat 9.55535-S3 may be used when SAE
5W-20 engine oil meeting MS-6395 is not available
Engine Oil Viscosity – 5.7L Engine (2500/3500
Models Only)
MOPAR SAE 5W-20 engine oil or equivalent Pennzoil®
or Shell Helix® is recommended for all operating temperatures. This engine oil improves low temperature
starting and vehicle fuel economy. The engine oil filler
cap also shows the recommended engine oil viscosity for
your engine. For information on engine oil filler cap
location, refer to “Engine Compartment” in “Maintaining
Your Vehicle” for further information.
NOTE:Vehicles equipped with a 5.7L engine must use
SAE 5W-20 oil. Failure to do so may result in improper
operation of the Multi-Displacement System (MDS). Refer to “Multi-Displacement System” in “Starting and
Operating” for further information.
Lubricants which do not have both the engine oil certification mark and the correct SAE viscosity grade number should not be used.
NOTE:For 2500/3500 trucks with a 5.7L engine operating under a gross combined weight rating of 14,000 lbs (6
350 kg) or greater, SAE 5W-30 engine oil is recommended
for all operating temperatures.
Engine Oil Viscosity – 6.4L Engine
Use Pennzoil UltraTM 0W40 engine or equivalent
MOPAR oil meeting the Chrysler Material Standard
MS-12633 for use in all operating temperatures.
The engine oil filler cap also shows the recommended
engine oil viscosity for your engine. For information on
engine oil filler cap location, refer to the “Engine Compartment” in this section.
