Lubrication of pistons is something I expect to need to do but rarely, once in years of use, but it's something I've needed to do right away after obtaining a used but new-to-me pen.
Lubricating a Pelikan by removing the nib to access the barrel is not a great way. Instead, one should use a wrench to remove the piston assembly (note that the threads are left-handed on a Pelikan!). That way you can apply the very small amount of lubrication needed directly to the
side of the piston head. Lubricating
ahead of the piston head has an effect only because the piston head can't squeegee it all, but it tends to cause an unhelpful glob of grease to form in the area where the ink is stored. The wrench required to remove a Pelikan piston is easy enough to obtain. TWSBI wrenches fit, for example.
My experience with Montblanc piston fillers is limited to 1980's and later 146's and 149's. They can be serviced in a similar way to Pelikans. It just requires a more specialized wrench to remove the piston assembly (and the threads are right-handed, BTW). I bought a wrench on eBay because the first Montblanc that I bought was in such need of lubrication, I worried about the amount of torque required to actuate the piston. NOT lubricating such a piston would be foolish, and it's either pay Montblanc to refurbish the pen or learn to do it yourself. Even with the right wrench, however, removing a Montblanc piston that has not been removed for many years can be difficult, and there is some risk of damaging the barrel in one way or another if you aren't careful. One of them took me months of repeated efforts with heat and wrench to loosen for the first time.
