This sewing machine / small mechanism oil is absolutely overkill for the job you’re doing. Some small wd40 usually does it. Fun fact: this is also a good way to keep your tools rust free! It functions well on preventing rust.
Edit: it’s not mineral oil or synthetic lubrificant is it?
I know. Unless you have really humid and rusty doors you shouldn’t even need lubrification. I personally I have never needed precise lubrification for doors. But that wd40 oh yes i needed it.
