ZIPPER
MASCHINEN
strongly
recommends the
usage
of
HQ
premixed
fuels
especially
recommended
for
2
-
stroke
motors
.
Many
of
them
keep
their
consistency
even
after
long
periods
of
storage
.
If
you
prefer
to
mix
your
own
fuel
please
use
HQ
Synthetic
Oil
for
2
-
stroke
engines
.
Synthetic
oil reduces accumulation
of
soot
on
the
spark
plug
,
cylinder
,
engine
cock and
exhaust
pipe
.
This increases
the
degree
of
lubrication and
prolongs
the
engines
lifespan
.
Use
self
-
mixed
fuel
up
within
4
weeks
