Can any one tell me what kind of oil to use in a B&M 671 blower? How much oil can these blowers hold? Thanks for any replies.

Gear oil.....80-90 weight or red line gear oil. If it is a 6-71blower, take the blower drive bolt out that is in the 8 O clock position and fill until the fluid runs out that set of threads. The bottom of a 6-71 or bigger blower has fluid about 1" deep in the front covevr.
