Oil Recommendations
Synthetic oil is recommended for use in
LPG/NG fueled engines. Non-synthetic oil must
be low ash* rated oil. Oils (including synthetic)
must meet API (American Petroleum Institute)
service class SG, SH, SJ, or SL. Select
viscosity based on air temperature at time of
operation as shown in table below.
*Low ash is defi ned as less than 1% sulfated
ash.
