    spark plug champion L77JC4.
    yes on high octane unless low compression head gaskets are install because this engine was designed for 92 and predetonationcan be likely.
    50:1 fuel to oil ratio this is 16oz oil to 6 gallons of gas or 475mL of oil to 22.75L of gas
    and last but most likely to start an argument oil type
    my two cent any tcw-3 oil that has an engine manufactors name on it (johnson, evinrude, mercury, yamaha, suzuki,so on and so forth.)
