Appendix A: Lubricants and Compatibility
The following table lists materials that are suitable or not
recommended for use with synthetic oil. As some oil
escapes into the compressed air, all components that
come into contact with the air (i.e., piping, filters, hoses,
tools, etc) must be compatible with synthetic oil.
Northern Tool recommends using synthetic oil after the
first 50 hour break in period.

Alternate Lubricants.
You may use a petroleum-based lubricant that is
premium quality, does not contain detergents, contains
only anti-rust, anti-oxidation, and anti-foam agents as
additives, has a flashpoint of 440ºF (227ºC) or higher,
and has an auto-ignition point of 650ºF (343ºC) or
higher.
See the petroleum lubricant viscosity table below. The
table is intended as a general guide only. Heavy-duty
operating conditions require heavier viscosities.
