I have been using this Ultra Pure Valve oil for a short time now, and I must say, it is the best oil I have ever used. My valves were giving me some minor sticking problems every now and again, but since using this valve oil, I have not had one problem at all. With the Ultra Pure slide grease, my horn is running lightning fast. This is a great product and I am recomending this to all of my brass playing friends.
