This is THE best trumpet valve oil hands down! Long lasting and you don’t need a lot of it. Also, it comes in three viscosities. I use #1 for my new horns with tight valves and #3 for my older horns that have some valve wear.
I have been using this slide grease for 20 years and it is the best! Here is a trumpet “life” hack, I only use it on the main tuning slide and the 2nd valve slide. For the 1st and 3rd valve slides I use Yamaha trombone slide oil.
I use this on my 1st and 3rd valve slides because I want them fast and loose and without any hangups. it has its own applicator so you don’t have to mess up your hands and it can be done quickly.
