Engine Oil Recommendations
Engine oil should be serviced in accordance with the rec-
ommendations of this manual to maintain product war-
ranty. Generac maintenance kits consisting of engine oil,
oil filter, air filter, spark plug(s), a shop towel, and a funnel
are available through an IASD.
This unit is filled at the factory with 5W-20 engine oil. After
the 30 hour break in, replace the oil with Generac propri-
etary 5W-20 Synthetic oil. Once synthetic oil is used, it
should be used for the life of generator. It is not recom-
mended to go back to a mineral oil. Do not use special
additives.
NOTE: If not already equipped, it is strongly recommen-
ded to use optional Cold Weather Start Kit for tempera-
tures below 32 °F (0 °C). Utilize the Generac proprietary
blended 5W-20 oil in all climates.
Weather and Maintenance Kits
The following kits are offered to keep a generator running
at its peak:
• Cold Weather Kit: Recommended for climates with
temperatures below 32 °F (0 °C).
• Extreme Cold Weather Kit: Recommended block
heater kit for protection in temperatures below 32 °
F (0 °C).
• Scheduled Maintenance Kit: Includes recommen-
ded parts to maintain generator. See
Maintenance Schedule
intervals.
For additional information, or to order any of these kits,
please contact an
representative.
Coolant Water Treatment
Use of incorrect coolants can damage the engine cooling
system. Use demineralized water or distilled water for
best results. Hard water causes scale deposits, which re-
duces cooling efficiency and raises internal temperatures,

possibly leading to engine damage. Use an anti-corrosive
to prevent corrosion in summer and anti-freeze to prevent
freezing in winter.
Dilute the anti-freeze based on a theoretical temperature
which is 9–18 °F (5–10 °C) below the lowest temperature
expected in the area. A ratio of 40–60% is most common
range.

IMPORTANT NOTE: Do not use propylene glycol type
coolant. Using the wrong coolant, mixing different
types of coolant, or even mixing different brands of
the correct type of coolant, can produce unsatisfac-
tory results, possibly leading to engine damage.
NOTE: Use only Generac 50/50 ethylene glycol type
coolant (available from any IASD).
Fuel Requirements
The stationary emergency generator may be equipped
with one of the following fuel systems:
• Natural gas (NG) fuel system
• Propane vapor (LPV) fuel system
Recommended fuels must have a BTU content of at least
1,000 BTUs per ft
at least 2,520 BTUs per ft
LPV. If converting to LPV from NG, a minimum LP tank
size of 250 US gal (946 L) is recommended. See Installa-
tion Manual for complete details and procedures.

Fuel System Configuration
The engine is factory configured to use either NG or LVP.
It is not field convertible between NG and LVP. Fuel mix-
ing and ignition timing are only set at the factory for the
specific fuel.
