Fuel Mix
This engine is certified to operate on
unleaded gasoline and oil with the
mix ratio 50:1.
Your two-stroke engine requires a
mixture of brand-name gasoline and
quality two-stroke engine oil with the

regular grade gasoline in your area is
lower, use premium unleaded fuel.
Fuel with a lower octane rating may
result in preignition (causing “pinging”)
which is accompanied by an increase in
engine temperature. This, in turn,
increases the risk of piston seizure
and damage to the engine.

The chemical composition of the fuel is
also important. Some fuel additives not
only detrimentally affect elastomers
(carburetor diaphragms, oil seals, fuel
lines etc.), but magnesium castings as
well. This could cause running problems
or even damage the engine. For this
reason it is essential that you use only
branded fuels!
