Loss of oil but no leaks on motor or underneath the car, no smoke either

Drove one night and was perfect, next day drove 5km and it was almost bunny hopping and sounded like a VW. Engine lights or oil lights have not come on at all, and i constantly check after owning a piece of crap Holden. Find it strangefine one day screwed the next. Any suggestions? ???

After I start my car it's producing smock most likely when drive three to five kilometres not only smoking but also consuming oil that,even oil light is appearing on dash board

I was driving when my car went out and it no longer starts, I have the steering wheel ! Light engine light ,oil light on, I replaced battery and spark plugs already and when I start it the pressure meter doesn’t do up what could be the problem

While i was driving i hit a small bump and i saw that the thermometer guage dropped and my oil light came on {i just did a oil change two weeks prior} and then the car doenst crank at all. The battery is good , the starter is bad so i bought a new one. I just dont know what caused the electrical issue. The right side of the interior fuse box are burnt starts at number 15 and goes on so it had to be all connected right ? how can i figure out which wire tho ?
