I have tried all of the synthetic valve oils:Hetman, La Tromba, Alyson and Space Filler. All of them gunked up the valves. I have been using the Dura Lube mix for two years now and have not had any problems. It's formulated to withstand the heat generated by automobile engines and not gum up. I assume most tubas run cooler than a 75 Dodge:)
Maybe it shouldn’t be used in cars ether? I know nothing about automobiles!
