Thanks.
I'm not sure why I just assumed that it was silicone, I have not looked at a bottle yet.
The treadmill oil will probably be very heavy and tacky.
I will have to find something else to use to thin it down with if I use it.
e2a: I'll try it straight first if it seems like it will work. Some treadmill oils are advertised as 500 cst so 350 might not be too heavy.
