CHANGING SUPERCHARGER GEARCASE OIL
IMPORTANT: Change the supercharger oil when the engine and
supercharger are warm from operation. Warm oil flows more
freely, carrying away more impurities. Use only the recommended
oil in the supercharger, see Specifications. If the oil level in the
sight‑glass has increased, decreased, or changed to an abnormal
color, it would indicate an internal problem with the supercharger.
