Petroleum-based oil works best with brand new trumpets. Petroleum oil is lighter and won’t be as effective on worn-in trumpets. You may have to reapply this oil more often if you use it on an older instrument. [1] X Research source Synthetic oils are typically more expensive, but they are better able to reduce friction in tighter valves. In addition, these oils do not evaporate as quickly, so you may not need to oil your valves as regularly with this type of lubricant. Try various types and brands of valve oil to see which you prefer. Each person’s experience will be different, and the oil will react differently to each person’s saliva! Be sure not to mix the synthetic oils and petroleum-based oils together.
If an oil label states “shake well before use,” this could indicate that it is a silicone-based oil. Be sure to read the labels before buying a valve oil.
The valves may seem sticky after oiling if debris collects on the oil. To fix this, gently remove the valve and wipe it with a clean cloth. Be sure to re-oil the valve before inserting it back in the trumpet.
