there can be 2 answers to your question 1 your fuel pressure regulator is leaking causing fuel to dump past the butterfly plates . 2 your uper compression rings are collapsed causing fuel to bypass the rings under compression eather one of these will cause fuel to get into the oil check
after a new oil change run your s10 a little while then shut it off pull off the air cleaner and with a flash light look to see if any fuel is leaking into the throttle body if not when key is off then with key on engine off and recheck
last do a compression test
