| Brushing engine oil onto the chain is effectivly what a Scotoiler does although i think they use something similar to chainsaw oil.
I seem to remember that most manufacturers recommend EP80/90 gear box oil as that withstands high pressures better than engine oil and is totally safe on all kinds of o rings.
I used to use castrol chain wax but as you say it does make everything go white and its difficult to get off. |
