Detroit Diesel lubricant recommendations are based on general experience
with current lubricants of various types and give consideration to the commer-
cial lubricants presently available.
Some new special arctic lubricants have recently been developed for Military
use in extremely cold eliminates. The oils that have shown best cold temperature
