Mexican oil change 

What happens when you have a car that's leaking or burning oil, so you frequently have to add oil to keep your engine from blowing up. Because of the constant consumption and addition of oil, your car always has fresh oil.

Yeah, the head gasket blew in my old hoopty. Now it burns a quart every week, so I'm doing the Mexican oil change.
