BREAK-IN PERIOD
CAUTION: Wide open throttle operation in low
gears, before engine break-in period is complete,
can damage engine.
Chrysler Corporation vehicle does not require an
extended break-in period. Driving speeds of not over
80-90 km/h (50-55 mph) for the first 100 km (60
miles) is recommended. Hard acceleration and high
engine rpm i n lower gears should be avoided.
SELECTING ENGINE OIL
CAUTION: Do not use non-detergent or straight
mineral oil when adding or changing crankcase lu­
bricant. Engine failure can result.
The factory fill engine oil is a high quality, energy
conserving, crankcase lubricant. The Recommended
SAE Viscosity Grades chart defines the viscosity
grades that must be used based on temperature i n
the region where vehicle is operated.
Chrysler Corporation recommends that Mopar mo­
tor oil, or equivalent, be used when adding or chang­
ing crankcase lubricant. The API symbol (Fig. 1) on
the container indicates the viscosity grade, quality

oil foaming and oil pressure loss can result.
Inspect engine oil level approximately every 800 k i ­
lometers (500 miles). Position vehicle on level sur-
