    Bought a 2013 Superjet, What oil, mix ration, and spark plugs to use?

    Hey guys I got a really good deal on a a clean low hours all stock 2013 Yamaha Superjet and have a few basic questions as I have not had a standup in a few years.

    1. With an all stock ski what oil do you suggest? Would liek to get something readily available in the Dallas Ft. Worth area.

    2. What is the proper mix ratio 40 or 50:1? AAlso is regular 87 octane ok?

    3. What is the correct part number of spark plugs needed?

    4. It is all stock and i plan on doing basic mods to it as I go but nothing to the engine to affect reliability. Looking at a intake grate, ride plate, and a pole spring possibly. Anyone got suggestions on which models to use and anyone have used parts for sale cheap?

    Thanks in advance.

    1. I use this brand of oil that I purchase from Academy Sports.
    https://lucasoil.com/products/2-cycl...-sea-oil-tc-w3

    2. The proper mix ratio is 50:1 with 91+ required.

    3. NGK B7HS are the stock spark plugs.

    4. For more mod info and used parts you should try this dedicated standup forum.

    Thank you much for the reply, I found an online owners manual and the gas said it was an 86 regular suggestion so not sure I need premium especially since the compression ratio is 7-.2 to 1.

    That Lucas oil looks good to me and I have an academy right next to me. How does it compare to Quicksilver, Pennzoil or Yamalube?

    I have used Yamalube as well but prefer the Lucus due to the less smoke formula and it is a TC-W3 semi synthetic formula.
    Stock you can use 87 octane. I have the MSD enhancer with advanced timing so I use a higher octane.
