So I've searched about using seafoam in my 03 cobra and I see people talking about sucking it through the intake and putting it in the oil but all I want to do is put it in my gas tank and just let it clean that way, no way I'm putting it in my oil. From what I read that seems to be fine for our cars to just put it in the gas tank but just wanted to be 100% sure. Also, while I'm running through the gas that has the seafoam in it should I not go to hard on my car?
