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.
