RECOMMENDED SAE VISCOSITY GRADE ENGINE OILS
40°F (4°C)
Select an engine oil viscosity that will best match the
prevailing daytime temperature.
The oil must meet GM specification 9986231. Motor oils
meeting this specification receive the API (American
Petroleum Institute) starburst symbol.
It is noted that the GF-4 oils are also “backwards compatible”
and are equal or better that previous grades of oil in all
aspects.
Checking Engine Oil Level
NOTICE
It is important to be careful when checking engine oil
level. Oil must be maintained between “ADD” and the “FULL”
mark on the dipstick. To ensure that you are not getting a
false reading, make sure the following steps are taken before
checking the oil level.
1. Stop engine.
1. Turn the generator off.
3. Remove control board fuse from control panel.
4. Allow approximately five minutes for the oil to drain
back into the oil pan.
5. Remove the dipstick. Wipe with a clean cloth or paper
towel and reinstall. Push the dipstick all the way into
the dipstick tube.
6. Remove the dipstick and note the amount of oil on the
dipstick. The oil level must be between the “ADD” and
“FULL” marks.
7. If the oil level is below the “ADD” mark, reinstall the
dipstick and proceed to step 8.
8. Remove the oil filler cap from the valve cover.
9. Add the required amount of oil to bring the level up to,
but not over the “FULL” mark on the dipstick. Reinstall
the oil filler cap to valve rocker arm cover and wipe
any excess oil clean.
