## Mineral oil for reciprocating compressors

COM-100-640 identifies Lubri-Loy's mineral-based reciprocating compressor oil in ISO 100 viscosity grade. This article covers the 5 gallon pail.

Check the compressor manufacturer's lubrication instructions before selecting an oil. The compressor type and required lubricant should match your equipment's requirements; a viscosity grade alone does not establish suitability for every machine.

## Understanding the catalog's 4,000-hour rating

The catalog description states Reciprocating Compressor Oil, Mineral, 4,000 Hour. That is the catalog-stated service rating for this oil.

Follow equipment documentation and maintenance guidance when planning oil changes. The catalog rating should not be treated as a universal oil-change interval for every compressor or operating condition.
