The oil level in this generator should be checked before each use. (See Figure 10.) When the oil level is low, add oil until the level is sufficient to
operate this generator.
The oil capacity for this ACDelco Model AC-G0003 5500 Surge Watts / 5000 Running Watts Portable Generator engine is 1.2 Qt.
(38 fluid oz.) (1.13 L).
To drain the oil from this generator:
It is necessary to drain the oil from the crankcase only if it has become contaminated with water and/or dirt.
