So I was driving on the interstate today going at about 75 mph a few seconds later wasn't even paying attention I was going about 96 mph and start to smell something burning smelt like a burnt clutch but I have a auto. Didn't think anything of it i thought it was the clunker in front of me. When I got home I still smelt it and i started to check the engine. i started the car and started To hear a light knocking sound had to listen close so i shut it off .I then found that there was no oil in the motor at all dip stick was dry There is no oil leaking anywhere i can see. I was going to change the oil this week because last week I checked it and it looked like it was time for an oil change and the dic said 48% oil life. I have oil on the way just need to know what I should do would appreciate it.
