AMSOIL Octane Booster
Product Highlight
AMSOIL Octane Booster improves performance and maximizes power in all two-cycle and four-cycle gasoline engines. Increases octane by 4 points.
Reduces engine knock, improves ignition and engine response, aids in cleaner fuel combustion, and protects against corrosion. Off-road and racing use is recommended.

Classic and Collector cars were designed to run on leaded gasoline back in the day.
As a result, antique and collector cars frequently require the use of a lead alternative in order to preserve components that were designed for older fuel. In older automobiles, AMSOIL Octane Boost is a good lead substitute. It boosts octane by four points, reducing engine knock and improving ignition while also making fuel burn cleaner.
Contains MMT (Methylcyclopentadienyl manganese tricarbonyl) which is a metallic additive that produces a sacrificial barrier on valve seats to assist prevent recession and keep your engine running strong. It works well as a lead substitute.

What is "engine knock" and why does it matter?
"Knock" is an uncontrolled and explosive ignition of a hydrocarbon fuel, such as gasoline, in the combustion chamber. It causes a knocking or pinging sound, robs the engine of power and, left unchecked, causes serious engine damage. Fuel's tendency to knock is measured by its octane number. Lower numbers denote greater knock tendency; higher numbers denote greater knock control. Knock may be eliminated with the appropriate octane number.
