Engine Break-In Recommendations
A long break-in period is not required for the engine and drivetrain (transmission and axle) in your vehicle.
Drive moderately during the first 500 miles (800 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 detrimental and should be avoided. Trailer tow is not recommended during break in period.
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. For the recommended viscosity and quality grades, refer to “Maintenance Procedures” in “Maintaining Your Vehicle”.
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 interpreted as an indication of difficulty.
