Klotz® Octane Booster is a concentrated tetraethyl lead substitute formulated to increase the octane rating of gasoline up to 10 numbers or more. 

Helps eliminate engine damaging detonation, spark knock, pre-ignition, and pinging from low octane gasoline.

Octane Booster modifies the burn speed and flash point of gasoline to create a stable combustion chamber flame front, maximizing performance and power.

Stabilizes oxygenated gasoline to prevent lean-out conditions.

Klotz® Octane Booster provides needed upper-cylinder lubrication that is missing in unleaded gasoline. 

Leaves no messy residue.

For gasoline only.
