It does not always have BIO!

This oil I would recommend owners of electric chain saws at any time.

For all others: I have not necessarily had the best experience in heavy use for two years. The oil consumption is considerably higher than other oils and when the chain saw is not used for six months, the gummy oil very easily. The then necessary cleaning and free punting is time consuming. It is certainly more environmentally friendly than mineral oils, but for all users who from time to time a few hours a year using the chainsaw and put emphasis on performance, ease of use and low consumption, I recommend rather DOLMAR or HUSQUARNA oils in mineral form!
