20KW Briggs & Stratton Whole House Generator – Oil Change.
Same Generator as:
GE 20KW Whole House Standby Generator
Rheem 20KW Whole House Standby Generator
One Thing that you should also do is to Pour Oil into the Oil Filter before you mount it on the Generator. This gets oil flowing immediately, so that engine does not get starved for oil and possibly suffer wear damage on the startup.
