    8 HP Merc 4 stroke questions

    I just bought a 2006 8 horse mercury motor. I did not receive an owners manual. I was hoping to get some recommendations on:

    Which oil to use

    Which lower unit oil

    Gas additives (Is Don's cocktail best?)

    is there an e-manual

    any other advice

    thanks for the help

    I'll share recommendations for my '09 8hp as I'm sure they're same.

    TCW certified 10w-30 for all air temps, 25w-40 if temps don't drop below +40F. Recommended lower unit oil is Mercury or Quicksilver High Performance. Use Don's cocktail every time you refuel. Spark plugs are NGK DCPR6E, gapped to .040" and torque to 20ft lbs. Recommended fuel is 87.

    If you're asking about an electronic service manual, no, they are copyright protected documents. Not sure about owner's manual, but you can surely order one from European Marine. I purchased factoryt service manual for my 8hp from European Marine.

    Since Mercury doesn't use years, post your engine serial number for most accurate response. For reference, mine is 0R263337.

    Hope that helps.
