    Jonsereds chain saw oil mix
    I recently purchased a used Jonsereds chain saw. It is an older model.
    What is the proper oil to gas ratio mixture. Is it 50 to 1 or 40 to 1 or
    Some other ratio?

    Hi,
    With today's gas, 50:1 is proper when done with a name brand oil made to be mixed that way. Do not skimp on the name brand.
    Peace,

    Nab is correct... unless you can verify exactly what the mfg. wants, 32 to 1 would be safe. And use 2 cycle oil only. Regular motor oil will not work. Too little oil will cause either premature cylinder, ring or piston wear... or all three. Post the model number here and someone will help you find the proper mix.

Chain saw [ 2 Answers ]

I have a 14" chain saw but haven't used it in several years. I put in gas and oil and it started right up. I changed the saw blade and added gear and sprocket oil. Now the saw smokes and drips oil. Also the blade doesn't come to a complete stop when the trigger is released. I moves at a slow pace...
