For five years now in over ten work saws, polesaws, top handles ect as well l have solely run canola. lt has more advantages than disadvantages mainly being cost but others include no skin irritation, safe to use near waterways where fish are ect. Spill some and the the resident dog will be seen promptly licking it up. l find lubrication better if anything with canola.....the oil company's won't tell you that though, its something you have to google or find out through experience. The biggest issue with canola IME is if you storing bars for extended periods the canola seizes/gums up in the nose sprocket so couple of shots of bearing grease solves that. Even sprockets that seize just need a whack on some wood to free them and a good run. I have not experienced any gumming in anything other than bar sprockets that have been stored for extended periods but now if storing them will clean/flush sprocket and inject lithium bearing grease. An interesting fact to be considered is that what l save not using petroleum base oil per saw per annum is in many cases enough money to replace the saw brand new. Kind of a no brainer IMO and experience.
