RUN-IN PERIOD
Reading edition
The First 1000 Miles (1609 km.)
It is desirable to limit driving speeds during the first 1000 miles (1609 km.) of operation in order that the closely fitted parts of the engine and chassis may have an opportunity to “wear in” smoothly.
For the first 500 miles (805 km.) it is recommended that you do not drive your car at speeds in excess of 50 miles (80,5 km.) per hour. For the second 500 miles (805 km.) it is recommended that you do not drive your car at speeds in excess of 60 miles (96,6 km.) per hour.
While it is always better to let your engine warm up at lower speeds, you should, by all means, follow such a practice during the first 1000 miles (1609 km.) of operation.
Further, it is well to avoid continuous high speed driving during the first 1000 miles (1609 km.) even though the engine has been warmed up.
Engine Oil During Run-In
The use of special run-in oils is not necessary. Use only engine oils produced by reputable oil companies.
During the run-in period it is important to change the oil shortly after the engine is put into operation. Therefore, change oil at least by the end of the first 1000 miles (1609 km.). After 1000 miles (1609 km.), change oil regularly. See page 32.
It is a good practice to have the oil level checked whenever gasoline is purchased. Keep oil at the Full mark. Do not overfill.
The viscosity of the oil to be used depends entirely upon prevailing temperatures. See page 33.
