A multi-season, environmentally friendly oil with excellent performance properties designed for lubricating chainsaws based on refined vegetable oil and a special combination of refining additives. The use of vegetable oil as a base means that PILAROL EKO can be classified as a highly biodegradable oil - in the OECD 301 F test carried out at the ICSO "Blachownia" analytical plant, it scored 81.6% biodegradability. A properly selected combination of additives ensures favourable functional properties, among others:- very good adhesion to moving parts of the equipment (saw cutting system), - suitable temperature characteristics that allow its use in a wide temperature range, - ability to protect against corrosion and abrasive wear.
