Oiling your trumpet valves is one of the most important parts of your instrument maintenance. Which oil do you need to choose for a better result—petroleum-based or synthetic oil? In this article, we will explore both oils, revealing their benefits and drawbacks.
Petroleum-Based Valve Oil
It’s the best option for those who have a tight budget. However, be aware that it may evaporate faster than synthetic oils, so you will need to regularly reapply it. Players also consider it a drawback that petroleum-based oils have a strong scent and leave residue on trumpet valves. They may also provide a more slippery feel.
Synthetic Valve Oil
It is comparatively more expensive, but you won’t need to reapply it too often, as it tends to last longer than petroleum-based oils. Musicians also appreciate synthetic valve oils because they don’t leave residue, and their smell isn’t so irritating. Also, players value them for providing a smoother feel.
Which Valve Oil to Choose?
It’s up to you to decide which one works better for your needs.
When it comes to synthetic valve oils, they are available in various levels of thickness. Thinner oils are better for new instruments with tight valve clearance, while thicker oils are better for vintage trumpets with a large valve clearance.
Some musicians who use petroleum-based oils stay loyal to a particular brand for years and don’t change it for something else. While other professional musicians who don’t want to waste time on frequent application and residues on their trumpet valves prefer synthetic oils.
The most commonly used petroleum-based oils are Al Cass and Blue Juice.
The most commonly used synthetic oils are Monster Premium, Ultra-Pure, Yamaha, Alisyn, Hetman, and more.
Things to Avoid When Using Valve Oils
Never mix various valve oils. Before switching from one type to another, always thoroughly clean any residues from the old valve oil. The pistons and the inside of the valve casing should not contain any particles.
How to Use Valve Oil
Prepare a bottle of valve oil, a trumpet, and a flat surface to lay your instrument on.
Put a cloth under the trumpet to avoid the oil leaving stains on the surface.
- Clean your valves and casings using a lint-free cloth. Ensure there is no residue left on the valves.
- Lay the trumpet on a flat surface or hold your instrument around the valve casing with your fingers and tilt it to about a 45-degree angle.
- Unscrew the top valve cap.
- Hold the valve at the top finger button and pull it up until the top of the main part of the piston is out of the valve casing. Avoid removing the valve completely.
- Take a bottle of oil, touch its nozzle to the main part of the valve, and drop 3 or 4 drops of oil into the valve casing by squeezing the bottle.
- Move the valve up and down a few times to distribute the oil.
- Push the valve back into the casing, holding it by the finger button. You will hear a ‘click’ as the valve settles into the correct alignment.
- Screw the top valve cap back on.
How to Avoid Common Mistakes When Lubricating Trumpet Valves
When lubricating your trumpet valves, avoid touching the main part of the valve with your fingers when moving it by holding the top finger button. This will prevent valve oil from getting on your hands and dirtying them.
Do not remove the valve completely - you just need to have enough space to apply oil around the piston. Otherwise, you increase the risk of damage or scratches. Also, it will prevent you from mixing the valves and placing them in the wrong positions.
Never oil only the bottom valve caps, as the oil won’t reach the necessary parts and, what’s more, may cause the valve to become sticky.
For better playability and a smooth feel, lubricate your trumpet valves once every few days. You especially need to reapply oil once your valves feel sluggish or get stuck.
