the requirements of Chrysler Material Standard MS-6395.

Engine Oil Viscosity (SAE Grade)
For 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.
For all other trucks with a 5.7L engine operating under a
gross weight rating less than 14,000 lbs (6,350 kg) SAE
5W-20 engine oil is recommended for all operating tem-
peratures. These engine oils improve low temperature
starting and vehicle fuel economy. Your 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 this section.
Lubricants which do not have both the engine oil certi-
fication mark and the correct SAE viscosity grade num-
ber should not be used.
