i changed the oil on my car today. my friend over at auto zone said put in this marvel mystery oil. it has a good reputation and actually works they say. dont know if anyone has used it or heard of it to get input on it. i put it in both my oil and gas cause it is good for both. my car does seem to be running a bit better. whether it is just from the oil change or this mystery oil.
