oil additives DODGE RAM 2500 DIESEL 2007 3.G Owners Manual

You may use synthetic engine oils provided the recom-
mended oil quality requirements are met, and the recom-
mended maintenance intervals for oil and filter changes
are followed.
Materials Added to Engine Oil
The manufacture strongly recommends against the addi-
tion of any additives (other than leak detection dyes or lube odorants) to the engine oil. Engine oil is an engi-
neered product and it’s performance may be impaired by
supplemental additives.
NOTE:
The manufacturer offers a lube odorant (Mopar
Diesel Fresh) for diesel engines crankcases. The lube
odorant is recommended by the manufacturer to reduce
the sulfur smell that may occur during engine idling.
Engine Oil Filter
Refer to Fluids, Lubricants and Genuine Parts for the
correct part number. The engine oil filter should be
changed at everyengine oil change.
Engine Oil And Filter — Change
Operate the engine until the coolant temperature reaches
140°F (60°C). Shut the engine off. Remove the oil drain
plug.
Use a container that can hold at least 12 quarts (11.3
Liters) to hold the used oil.
386 MAINTAINING YOUR VEHICLE

It is important that proper lubricant is used in the
transmission. Refer to Fluids, Lubricants and Genuine
Parts for the correct lubricant type. A band adjustment
and filter change should be made at the time of the oil
change.
The fluid and filter(s) should be changed and the bands
adjusted (if equipped) ) as specified in the Maintenance
Schedule (Section 8). Vehicles having severe usage should
follow Maintenance Schedule “B” of the Maintenance
Schedule (Section 8).
Severe usage consists of:
•Off-the-highway operation;
•Trailer towing;
•Snow plow operation;
•Prolonged operation with heavy loading, especially in
hot weather. NOTE:
If the transmission is disassembled for any
reason, the fluid and filter should be changed, and the
bands adjusted (if equipped).
Special Additives
The manufacturer recommends against the addition of
any additives to the transmission. Exception to this
policy is the use of special dyes to aid in detecting fluid
leaks. The use of transmission sealers should be avoided,
since they may adversely affect seals.
Front Wheel Bearings
Front wheel bearings for all Dodge Ram Trucks are
sealed-for-life. They do not require greasing or seal
replacement. In some instances, these bearings will
“purge” excess grease and the bearing housing will look
slightly wet. This is normal.
•Periodic inspection for excess play is recommended.
