Simpler and more powerful than 4-stroke engines, two-stroke engines require high-quality pre-mix oils for optimum performance and longer life. TWD-STR KE LUBRICATION O All two-stroke moving engine parts require constant lubrication to reduce friction and wear. Lubrication is accomplished by burning a mixture of two-stroke oil and fuel that 1-."""1:::11 is carried through the crank.......JL~ case. lubricating the crankshaft. rod, pin and cylinder wall. Without proper lubrication. engine wear and engine seizure are inevitable. O nly PJ1 Goldfire Premix oils have been scientifically . IGNITION formulated 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.. +=~~'~1E • High film strength to "'" 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 engines. PJl offers three different pre-mixoils tocover all two-stroke R PM/applicatio ns: • Injection /Premix for general. all purpose uses such as scooters and other low RPM engines. oldfire P remix for medium size • G engines, dirt bikes, ATV, motocross, and enduro riders. ro • Goldfire P is the ultimate for high RPM motocross and road racing engines. . ..

"I've been riding for over 30 years but PJI taught th is old dog some new tricks. While my competitors, using other premixes had to change out rings every 24 hours, my PJI Goldfire and Octane Plus met every enduro challenge 'with maximum power and no breakdowns.
