If the instrument is new and tight. And if you have not yet found an optimal handposition. Then you might press the 1st piston slightly outward. Resulting in an adhesive effect between the piston and the casing.
Work on your hand position and the angle the fingers strike the pistons.
As for oiling you might have luck with my approach: To use a fairly thin oil mixed with a little of a somewhat heavier oil. But I can not say, how it will work in your climate, so you will have to do your own experiments. Start out with a few drops of "heavy" to a bottle of "light". And make sure that the emulsion is well shaken, before you apply it.
