104+ Performance Max Octane Boost & Lead Substitute — Concentrated Detergent Formula, Valve-Seat Protection

104+ Performance Max Octane Boost & Lead Substitute raises octane, reduces engine knock, and acts as a lead replacement for vehicles needing supplemental protection.

If regular octane boosters aren’t stopping pinging or aren’t giving you the smooth throttle response you want, 104+ Performance Max is formulated to help. It’s a concentrated octane enhancer that also contains compounds that substitute for lead where additional valve and seat protection is desired. Beyond detonation control, the formula helps clean fuel-system deposits which can improve throttle response and fuel economy under load.

How does this product reduce engine knock and improve performance?

104+ raises the effective octane rating of the fuel in your tank, which helps prevent premature combustion (knock). That smoother burn reduces hesitation and allows engines designed for higher octane to perform closer to their intended power output.

• Increases fuel resistance to detonation for smoother combustion
• Helps maintain stable ignition timing under load
• Reduces audible pinging and roughness during acceleration

Will it protect valve seats and replace lead in older engines?

Yes — the formula contains lead-substitute additives intended to provide similar lubricity and protection to valve seats in engines that historically used leaded gasoline. It helps preserve valve and seat integrity when running modern unleaded fuels.

• Lead-alternative chemistry to reduce valve-seat recession risk
• Useful for classic cars, small engines, and high-mileage units
• Designed for use according to manufacturer recommendations and dosing guidelines

How should I use 104+ Max Octane Boost for best results?

Follow the product dosing instructions for the volume of fuel in your tank and add before refueling when possible to ensure full blending. For persistent knock or high-performance applications, some users add the recommended dose every fill or before heavy load periods.

• Dose based on tank capacity per label directions for consistent octane gain
• Add before filling to promote thorough mixing with fresh fuel
• Use regular maintenance dosing for ongoing deposit control and protection

What additional benefits does it provide to the fuel system?

Beyond octane boosting and lead substitution, 104+ includes detergents and deposit-control agents to help clean injectors and intake valves. Cleaner components can restore fuel economy, reduce rough idling, and improve throttle response over time.

• Removes common fuel deposits from injectors and intake passages
• Can improve fuel economy by restoring efficient fuel flow
• Helps maintain consistent engine performance between services

Who is this for: 104+ Performance Max Octane Boost & Lead Substitute is aimed at drivers who need higher effective octane — including owners of high-compression, turbocharged, or tuned engines — and operators of older or classic vehicles that benefit from lead-replacement protection. It also suits motorists seeking deposit control and improved throttle response without changing fuels. Always follow vehicle manufacturer guidance and the product’s dosing instructions before use.
