This premium oil is engineered for use at the speeds, loads and temperatures encountered in centrifugal supercharger applications. A single 12oz bottle provides the amount of oil needed to complete one oil change on a Centrifugal Specialties R-series (R106, R112, etc.) self-contained supercharger. Superchargers used with our external oil circulation pump may be used with 16oz of oil if used with an external filter (100 micron recommended). This oil is also suitable for use in ProCharger self-contained superchargers.
