The oil light on my car says -2100% i need an oil change. Bottom bottom nut that holds the oil in on the oil PAN. It doesn't screw in. So if I take it out, I need a whole new oil PAN, and we not doing that.
You gotta just get one of those expanding gasket things. It's like a plug, kinda. That's what im using. That was also what my daughter was using until recently.
