ENGINE BREAK-IN RECOMMENDATIONS
A long break-in period is not required for the engine in
your vehicle.
Drive moderately during the first 300 miles (500 km).
After the initial 60 miles (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.
Wide-open throttle acceleration in low gear can be detri-
mental and should be avoided.
The engine oil installed in the engine at the factory is a
high-quality energy conserving type lubricant. Oil
changes should be consistent with anticipated climate
conditions under which vehicle operations will occur.
The recommended viscosity and quality grades are
shown in “Engine Oil”, under “Maintenance Procedures”
in section 7 of this manual. NON-DETERGENT OR
STRAIGHT MINERAL OILS MUST NEVER BE USED.
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 inter-
preted as an indication of difficulty.
