ENGINE OIL RECOMMENDATIONS
We recommend the use of high-quality detergent oils acceptable if
classified for service SF, SG, SH, SJ or higher. DO NOT use special
additives.
Outdoor temperatures determine the proper oil viscosity for the
engine. Use the chart to select the best viscosity for the outdoor
temperature range expected.
SAE 30*
SAE 30*
10W-30**
10W-30**
5W-30
5W-30
* Below 50°F (10°C) the use of SAE 30 will result in hard starting.
** Above 80°F (27°C) the use of 10W30 may cause increased oil consumption.
Check oil level more frequently.
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.
NOTE:
The engine is equipped with an "Oil Alert System". This
system will automatically stop the engine before the oil level
falls below a safe limit. To avoid the inconvenience of an
unexpected shutdown, always check the engine oil level before
startup.
