Oil Recommendations
NOTE: When adding oil to the engine crankcase, use
only high quality detergent oil classified "For Service SF,
SG, SH, SJ" or higher. DO NOT use special additives.
1. Choose a viscosity according to the following table:
*Check oil level frequently at higher temperatures.
NOTE: Synthetic oil meeting ILSAC GF-2, API
certification mark and API service symbol with "SJ/CF
ENERGY CONSERVING" or higher, is an acceptable oil at
all temperatures. Use of synthetic oil does not alter
required oil change intervals.
SAE 30: 40 °F and higher (5 °C and higher) is good for all
purpose use above 40°F, use below 40°F will cause hard
starting.
10W-30: 0 to 100 °F (-18 to 38 °C) is better for varying
temperature conditions. This grade of oil improves cold
weather starting, but may increase oil consumption at
80°F (27°C) or higher.
Synthetic 5W-30: -20 to 120 °F (-30 to 40 °C) provides
the best protection at all temperatures as well as
improved starting with less oil consumption.
5W-30: 40 °F and below (5 °C and below) is
recommended for winter use, and works best in cold
conditions.

Checking and Adding Oil
Oil level should be checked prior to each use or at least
every 8 hours of operation. Keep oil level maintained.
1. Make sure unit is on a level surface.
2. Remove roof (see Removable Roof and Battery
Access section).
3. Remove oil fill cap/dipstick and wipe clean with cloth.
4. Verify oil level is at the FULL mark on dipstick
(Figure 14).
Figure 14 — Oil Fill Range
5. If needed, slowly pour oil into oil fill opening.
RECHECK oil level. DO NOT overfill.
6. Replace and tighten dipstick.
7. Replace roof.
Changing Engine Oil and Filter
Remove the two screws from each plastic access cover
and remove both access covers from the two sides of the
generator enclosure.
Changing Oil
1. Slide oil drain tube from hose clamp and place oil
drain tube into approved container.
2. Push in and rotate oil drain fitting 1/4 turn
counterclockwise. Slowly pull outward until oil starts
draining (Figure 15). DO NOT pull oil drain fitting
off.
