4.2.2 Oil Check
The generator set is shipped with oil. Before operating the generator set, check the engine oil in the crankcase.
To check the oil level, shut down the generator set and wait several minutes. Remove the dipstick and wipe the end clean,
reinsert, and remove. See Figure 54. Maintain the oil level between the Add and Full marks on the dipstick. Add 5W-30 or
10W-30 synthetic oil when the oil level is low.
Check the oil level before each use. For extended operation, check the oil level every 8 hours. Do not check the oil level when
the generator set is running. Shut down the generator set and wait several minutes before checking the oil.

4.2.3 Engine Oil Recommendation
Use 5W-30 or 10W-30 API (American Petroleum Institute) Service Class SG, SH, or SJ synthetic oil. Synthetic oil oxidizes and
thickens less than other oils and leaves the engine intake valves and pistons cleaner.
