Avoid using any oil other than the des-
ignated type.

Use a thoroughly blended fuel-oil mix-
ture.

If the mixture is not thoroughly blend-
ed, or if the mixing ratio is incorrect,
the following problems could occur:
Low oil ratio: Lack of oil could cause
major engine trouble, such as piston
seizure.
High oil ratio: Too much oil could cause
fouled spark plugs, smoky exgaust, and
heavy carbon deposits.
NOTE:
If using a permanently installed tank, pour
the oil gradually as the fuel is being
added to the tank.
