Why don't instant noodles ooze oil
According to Wikipedia, "The dried noodle block was originally created by flash frying cooked noodles, and this is still the main method used in Asian countries, but air-dried noodle blocks are favored in Western countries."  (from   https://en.wikipedia.org/wiki/Instant_noodle   ) So I don't know where you are, but if it happens to be a "Western country", maybe that's why.
