waste oil as chainsaw lube?

[happybonzo]

I must admit that I had not considered the aerosol effect from chain oil; presumably the spray from "normal" chain oil is equally harmful?

My experience over 40 years now is that specific chain oil is a must with its sticky property's on blades of over 24 inches under that as long as you use something it doesn't seem a problem. The biggest cause of damage to the blade is jamming in the wedge of a tree that you are cutting; over time this will cause the groove down the blade to subtly open out and the saw will no longer cut so well.

Ah. Wise words from woodbodger there which explains much, to me anyway who has much to learn it would seem. Ho hum.

@happybonzo: the same carcinogens aren't present in new oil.

One of the advantages given for using biodegradable chainsaw oil is that it's basically cooking oil rather than a mineral oil so liable to be better for you to breath in (if slightly fattening ;) )

@ "wrekin" - that explains a lot then: I'll blame chainsaw oil spray next week at Slimming World 8-))
