Max-Restore High Mileage Fuel System Treatment

Royal Purple® Max-Restore High Mileage is a highly concentrated, high performance fuel treatment that is specially formulated to solve performance problems typically found in higher mileage vehicles.

Key Benefits

  • Restores Fuel Economy

  • Extends Engine Life

  • Improves Responsiveness

Poor fuel economy

  • Many older cars and trucks have reduced fuel economy due to poor combustion primarily caused by high levels of carbon deposits and friction/wear.

Higher emissions causing failure of emissions testing

  • Carbon deposits and wear can create higher emissions that make it difficult for the vehicle to pass emissions testing

Wear on critical parts

  • As the miles add up, wear, friction and heat can prematurely age a vehicle

Loss of performance

  • Carbon deposits that have developed over the years are harder to remove than those found on newer vehicles. Until those are removed the engine will have poor acceleration, hesitation, and hard starting.

Max-Restore contains a high dose of polyether amine (PEA) & proprietary detergents that quickly clean stubborn, long-term deposits, often found in high mileage engines, that clog injectors and provides a protective barrier to keep new deposits from forming.

This optimizes the injector spray pattern and better atomizes fuel as it enters the combustion chamber resulting in enhanced power and performance, reduced emissions, smoother idle, and quicker / easier starts.

It also utilizes friction modifier to reduce wear in the upper cylinder to help extend engine life and improve fuel economy.

PERFORMANCE ADVANTAGES

  • Fuel economy – Restores fuel economy up to 5.9%
  • Emissions – Lowers emissions up to 14.8%
  • Wear – Reduces wear by lubricating key fuel system parts and extends engine life
  • Performance – Restores injector flow by up to 78.5%

    ⁦My wife’s Chrysler 300 has been throwing misfire codes. Before going to get a tune-up we put in a couple of bottles, one at each fill up. The effect was noticeable on day one. Once the codes were cleared, they did not return. That’s a huge + in my book.
