I read that every interjection should be separated from the sentence, no matter where it's placed, with a comma. If that's true, would phrases such as these require a comma after "oh"?
"Oh yeah" or "oh, yeah"?
"Oh my God" or "oh, my God"?
I feel as if the phrases "oh yeah" and "oh my god" are both treated as interjections and that they shouldn't need a comma after the "oh." Am I wrong, or is there a rule to this?

First off, that sounds like a made up grammar rule, so I wouldn't worry about it too much either way.
But to your question, you can insert or not insert the comment depending on what effect you want to convey.
Putting a comma in there could make it sound like there is a slight pause after "oh". You might want to omit the comma if you want it to sound like Bob in the Bob's Burgers clip Andrew posted. That is, with no pause.
Either way, it really doesn't matter much
