Oil Recommendations
Using the proper type and weight of oil in the crankcase
is extremely important. So is checking oil daily and
changing oil regularly. Using oil that is incorrect or dirty
can cause premature engine wear and failure.
Synthetic oil is recommended for use in LPG-fueled
engines because there is less oxidation or thickening,
and deposit accumulation on intake valves is
substantially reduced. Conventional petroleum-based oil
may be used, but valve service will be required every
500 hours to remove the accumulated deposits.
Dual-fueled engines can use conventional oil without
requiring speciaVadditional valve service.
Oil Type
Use high quality, oil of API (American Petroleum
Institute) service class SG, SH, SJ or higher. Select
the viscosity based on the air temperature at the time of
operation as shown in the following table.

TEMPERATURE RANGE EXPECTED BEFORE NEXT OIL CHANGE
NOTE: Using other than service class SG, SH, SJ or
higher oil or extending oil change intervals
longer than recommended can cause engine
damage.
A logo or symbol on oil containers identifies the API
service class and SAE viscosity grade. See Figure 3.
