5-1. FUEL

Use regular grade unleaded gasoline mixed with Genuine
Factory Parts 40:1 custom 2-cycle engine oil for best
results. Use mixing ratios in Section 5-3.
Never use straight gasoline in your unit. This will
cause permanent engine damage and void the man-
ufacturer's warranty for that product. Never use a fuel mix-
ture that has been stored for over 90 days.
If 2-cycle lubricant other than Genuine Factory Parts
Custom Lubricant is to be used, it must be a premi-
um grade oil for 2-cycle air cooled engines mixed at a 40:1
ratio. Do not use any 2-cycle oil product with a recom-
mended mixing ratio of 100:1. If insufficient lubrication is
the cause of engine damage, it voids the manufacturer's
engine warranty.

5-2. MIXING FUEL

Add oil to an approved fuel container followed by the gaso-
line to allow incoming gasoline to mix with oil. Shake con-
tainer to ensure thorough mix.
Lack of lubrication voids engine warranty. Gasoline and
oil must be mixed at 40:1.
