fuel type DODGE RAM 4500 CHASSIS CAB 2009 4.G Owners Manual

WARNING! (Continued)
•Unequal tire pressures from one side of the ve-
hicle to the other can cause the vehicle to drift to
the right or left.
•Always drive with each tire inflated to the recom-
mended cold tire inflation pressure.
Economy
Improper inflation pressures can cause uneven wear
patterns to develop across the tire tread. These abnormal
wear patterns will reduce tread life resulting in a need for
earlier tire replacement. Under-inflation also increases
tire rolling resistance and results in higher fuel
consumption.
Ride Comfort and Vehicle Stability
Proper tire inflation contributes to a comfortable ride.
Over-inflation produces a jarring and uncomfortable
ride.
Tire Inflation Pressures
The proper cold tire inflation pressure is listed on the
driver’s side “B” Pillar.
Some vehicles may have Supplemental Tire Pressure
Information for vehicle loads that are less than the
maximum loaded vehicle condition. These pressure con-
ditions will be found in the “Supplemental Tire Pressure
Information” section of this manual.
The pressure should be checked and adjusted as well as
inspecting for signs of tire wear or visible damage at least
once a month. Use a good quality pocket-type gauge to
check tire pressure. Do not make a visual judgement
when determining proper inflation. Radial tires may look
properly inflated even when they are under-inflated.

Change Engine Oil
Refer to the “Maintenance Schedule” in Section 8 for the
proper maintenance intervals.
Engine Oil Selection
For best performance and maximum protection under all
types of operating conditions, the manufacturer only
recommends engine oils that are API certified and meet
the requirements of Chrysler Material Standard MS-6395.
American Petroleum Institute (API) Engine Oil
Identification Symbol
This symbol means that the oil has
been certified by the American
Petroleum Institute (API). The
manufacturer only recommends
API Certified engine oils.
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.
