ETW()..STROKEENGINE
The power center of your bike. Simpler
and more powerful than 4-stroke engines,
two-stroke engines require high-quality
pre-mix oils for optimum performance and
longer life.
TW()..STROKELUBRICATION
All two-stroke moving engine parts require
constant lubricationto
reduce friction and wear.
Lubricationis accomplished .._J~~~~
by burning a mixture of
two-stroke oil and fuel that """'-....::::lI
is carried through the crankcase, lubricating the
crankshaft, rod, pin and
cylinder wall.
Without proper lubrication,
engine wear and engine
seizure are inevitable. Only
PJ1 Goldfire Premix oils
have been scientifically
IG
NITION '
formulated from the ground up ...for each
RPM lapplication, to provide a superior protective lubrication barrier that won't burn
. or wear off when used according to
manufacturer's specifications.
What to look for in a two-stroke
pre-mix oil.
• Clean burning to avoid
spark plug fouling and
gummy engine deposits.
• High film strength to
reduce friction and
increase horsepower
and engine life.
• C
onsistent viscosity and
formulation for predictable performance... even
• with different gasolines.
• Formulation to fit
differ.ent riding purposes,
EX
HAUS &
T
i.e., small engines like
TRANSFER
scooters require different lubrication
than high RPM race engines.
PJl offers three different pre-mix oils to cover
all two-stroke RPM
/applications:
Injection IPremix for general, all
purpose uses such as scooters and
other low RPM engines.
• Goldfire Premix for medium size
engines, dirt bikes, ATV, motocross, and
enduro riders.
• Goldfire P is the ultimate for high RPM
ro
motocross and road racing engines.
