Frequently Asked Questions
What does Rislone Octane Booster do?
Antiknock formulation stops engine knocks and pings caused by low quality fuel.
What is spark knock?
Spark knock, also known as knock, detonation, knocking or pinging in gasoline engines is when the air/fuel mixture in the cylinder explodes separately from the main ignition caused by the spark plug. This usually creates a metallic “knock” sound as the two fronts collide with each other causing extreme pressure inside the cylinder and possible engine damage.
Can I use with any type of gasoline?
Yes, Rislone Octane Booster works with unleaded gasoline, ethanol E10 E15 E85 flex fuels and racing fuel.
