    Advanced Bi-Metallic Liner. This process uses a double layer of
    plating material rather than one thick layer. This helps the metal
    to bond to the cylinder and is more durable. Also, the plating
    process is more consistent, resulting in a more precise fit between
    piston and sleeve for better compression, longer life.

    Fuel containing 5%-20% nitromethane with at least 16% lubricant
    Most of the fuels we carry meet or exceed the lubricant content
    required for optimum performance and maximum engine life. In the
    past, the conventional lubricant content used in fuel was 18%. But
    with new advanced technologies, fuels like Red Alert and O'Donnell
    for example, have a better quality of lubricants even though the
    percentages of lubricant content are lower. These high-tech
    lubricants provide exceptional cooling and protection.
