I have a 2004 mazda 3S with a 2.3L engine and I have alot of prblems with it but the one that im most concerned about is that theres never any oil left in the engine no matter how manny time I fill it it leaks out I have checked it a couple of times but I have never found a leak theres no leak spots in my driveway and when I start it and rev it black gunk comes out of my muffler

If its not leaking externally-that oil has to go somewhere-perhaps its being burn in the combustion chamber/cylinders. Blue smoke indicates oil is burning-black is for rich mixture more fuel then air is being burned-Verify the smoke
