Are there any good eyeliners for daily makeup on oily skin?

My skin is oily, so it tends to be quite greasy.
Also, perhaps because of the hot weather these days and the amount of sweating, my eyeliner gradually smudges and wears off by the afternoon after I apply it.
I also tend to prefer eyeliners that draw a natural line for daily makeup.
I don't find myself reaching for eyeliners that are too thick or dark, perhaps because they make my makeup look a bit excessive.
Is there an eyeliner that draws thinly and naturally yet has good staying power?
Please recommend an eyeliner that isn't too dark and draws a natural line.
