I've tried most of the popular valve oils over the years, and I always return to La Tromba, when I can get it. Luckily that's not a problem now that Thomann stock it.
I find La Tromba valve oil works the best in all of my trumpets, whether vintage or modern.
I can feel the difference when comparing it with other well known makes, the valves are definitely faster acting and smoother, and.......it smells better than a lot of the paraffin based lubricants.
If you haven't tried it, give it a go, I'm sure that you'll notice the difference.
