SRT ENGINE BREAK-IN RECOMMENDATIONS
A long break-in period is not required for the drivetrain
(engine, transmission, clutch, and rear axle) in your new
vehicle.
Drive moderately during the first 500 mi (800 km). After
the initial 60 mi (100 km), speeds up to 50 or 55 mph
(80 or 90 km/h) are desirable.
While cruising, brief full-throttle acceleration within the
limits of local traffic laws contributes to a good break-in.
However, wide-open throttle acceleration in low gear can
be detrimental and should be avoided.
The engine oil is a high performance synthetic lubricant,
the transmission fluid and axle lubricant installed at the
factory is high-quality and energy-conserving. Oil, fluid,
and lubricant changes should be consistent with antici-
pated climate and conditions under which vehicle opera-
tions will occur. For the recommended viscosity and
quality grades, refer to “Maintenance Procedures” in
“Maintaining Your Vehicle”.
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 a normal part of the break-in and
not interpreted as an indication of difficulty.
