2008 CHRYSLER 300 SRT oil viscosity

The engine oil, transmission fluid, and axle lubricant
installed at the factory is high-quality and energy-
conserving. Oil, fluid, and lubricant changes should be
consistent with anticipated climate and conditions under
which vehicle operations will occur. The recommended
viscosity and quality grades is shown in Section 7.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral Oil
in the engine or damage may result.
NOTE:A new engine may consume some oil during its
first few thousand miles (kilometers) of operation. This
should be considered as a normal part of the break-in and
not interpreted as an indication of difficulty.
SAFETY TIPS
Transporting Passengers
NEVER TRANSPORT PASSENGERS IN THE CARGO
AREA.
WARNING!
It is extremely dangerous to ride in a cargo area,
inside or outside of a vehicle. In a collision, people
riding in these areas are more likely to be seriously
injured or killed.
Do not allow people to ride in any area of your
vehicle that is not equipped with seats and seat belts.
Be sure everyone in your vehicle is in a seat and
using a seat belt properly.
74 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Change Engine Oil
Refer to the Maintenance Schedule in Section 8.
NOTE: Under no circumstances should oil change
intervals exceed 6,000 mi (10 000 km) or six months,
whichever occurs first.
Engine Oil Selection
For best performance and maximum protection under all
types of operating conditions, the manufacturer only
recommends full synthetic engine oils that meet the
American Petroleum Institute (API) categories of SM or
SM/CF, and meet the requirements of DaimlerChrysler
Material Standard MS-10725.
The manufacturer recommends the use of a full synthetic
engine oil, such as Mobil 1SAE 0W-40 or equivalent.
Engine Oil Viscosity (SAE Grade)
SAE 0W-40 engine oil is preferred for use in 6.1L Engines
within the operating temperatures shown in the engineoil viscosity chart. SAE 5W-40 Engine Oil is also allowed
for use in 6.1L Engines. The proper SAE viscosity grade
of engine oil should be selected based on the following
recommendation and be within the operating tempera-
ture shown in the engine oil viscosity chart.
392 MAINTAINING YOUR VEHICLE

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 Com-
partment” illustration in this section.
Materials Added to Engine Oil
The manufacturer strongly recommends against the ad-
dition of any additives (other than leak detection dyes) to
the engine oil. Engine oil is an engineered product and its
performance may be impaired by supplemental addi-
tives.
Disposing of Used Engine Oil and Oil Filters
Care should be taken in disposing of used engine oil and
oil filters from your vehicle. Used oil and oil filters,
indiscriminately discarded, can present a problem to the
environment. Contact your authorized dealer, service
station, or governmental agency for advice on how and
where used oil and oil filters can be safely discarded in
your area.
Engine Oil Filter
The engine oil filter should be replaced at every engine
oil change.
Engine Oil Filter Selection
This manufacturer’s engines have a full-flow type oil
filter. Use a filter of this type for replacement. The quality
of replacement filters varies considerably. Only high
quality filters should be used to assure most efficient
service. MoparEngine Oil Filters are a high quality oil
filter and are recommended.
Drive Belts — Check Condition and Tension
Belt tension is controlled by means of an automatic
tensioner. Therefore, no belt tension adjustments are
required. However, belt and belt tensioner condition
should be inspected periodically and replaced if re-
quired. Improper belt tension can cause belt slippage and
failure. Low generator belt tension can cause battery
failure.
