Octane boosters are typically only used for high-horsepower engines that have a turbocharger or superchargers. Octane boosters won't help much with naturally aspirated vehicles, so don't waste your money.

Vehicles with a turbocharger or supercharger put more air into the combustion cylinder, causing more compression. Adding an octane booster to your fuel tank will help suppress the compression, which will help avoid engine knocking.

Vehicles with high horsepower can benefit from adding an octane booster. However, it's essential to know that an octane booster will not increase your car's speed, horsepower, or torque. All the octane booster will do is help the engine avoid knocking or pinging.

It's pretty simple to add an octane booster to your vehicle. Most octane boosters like the one made by Lucas Oil will treat up to 15 gallons of fuel.

To add the octane booster, be sure that your fuel tank is close to empty, and add the whole bottle of octane booster. Then fill your vehicle full of fuel. Be sure to read the instructions of any octane booster to be sure of the recommendations.

If you have a project car that has high horsepower, then octane boosters will help avoid engine knock. But remember that there can be damage to your engine if you don't use it correctly.

Moreover, some vehicles do not require an octane boost at all. Therefore, it wouldn't hurt to speak to a performance shop for advice.

Any mechanic shop that specializes in increasing the performance of turbocharged or supercharged vehicles will be able to help you out.
