Hi There,
I have a question concerning valve oil.  Is there really a difference between it and a light machine oil (sewing machine oil, for example)?  It sure doesn't look terribly different.  Is valve oil specifically engineered for brass instruments?  If so, how?  I ask for two reasons:
1)  It seems vaguely ridiculous to me to pay up to $3.00 for two ounces of oil, if a similar or identical oil is available at a local hardware store for much less.
2)  There are no music stores in my immediate area, though there is a hardware store just down the road.
I need to get some oil soon, and before I drive off to the music store, I was wondering if I could get some thoughts on this.
