THE TWO-STROKE ENGINE
The power center of your bike. Simpler
and more powerful than 4-stroke engines.
two-stroke eng ines require high-quality
pre-mix oils for optimum performance and
longer life.
TWO-STROKE LUBRICATION
All two-stroke moving engine parts require
constant lubrication to
reduce friction and wear.
Lubrication is accomplished =-.i~~=:::1:
by burning a mixture of
p=
two-stroke oil and fuel that
is carried throughthe 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
IGNITION
formu lated from the ground up ...for each
RPM /application, 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 +E;:;~~tJi
reduce friction and
increase horsepower
and engine life.
• Consistent viscosity and
formulation for predictable performance ... even
with different gasolines.
• Formulation to fit
different riding purposes.
EXHAUST &
i.e., small engines like
TRANSFER
scooters require different lubrication
than high RPM race eng ines.
PJ 1oilers three different pre-mix oils to cover
all two-stroke RPM/applications:
• Injection /Premix for general, all
purpose uses such as scooters and
other low RPM eng ines.
• Goldfire Premix for medium size
eng ines, dirt bikes. ATV. motocross, and
enduro riders.
• Goldfire Pro is the ultimate for high RPM
motocross and road racing engines.
