Well This Is My Fourth Pregnancy &'d I Tried Castrol Oil With My 3rd ..... I Was Desperate &'d I Was Ready For Everything To Be Over With ; So I Mixed Some Castrol Oil In Orange Juice.... Waited Almost 30-50 Mins &'d Nothing Happened ; I Think The Next Couple Of Days I Went To The Hospital &'d I Was Dilated 4cm So The Doctor Admitted Yo The Hospital.... Well They Ended Up Breaking My Water Bag &'d Saw That I Had Some Poop In The Amoic Fluids... So No It Didn't Work For Me... But Maybe It Will For You 😀
