I took my car in to the dealer for an oil change, picked it up tonight and drove about a mile and the car stalled out on me. when i restarted it there was a slight knocking noise and i heard one small screaching sound. i immediately drove it back to the dealer, checked the oil and it was at the minimum. the head technician there at the time wanted to fill it up and i told him to leave it alone and i would come back and see the service manager in the morning. i left and came back 30min. later because i did not feel comfortable with not having the key and it being locked and the guy had already put more oil in it and said the noise was gone. What should i do. do you guys think my motor is shot now from the noises i described and what action does anyone think i should take? The technician there was trying to bullshit me and tell me that he doesnt think ill ever see a problem from it but i disagree. Any info will definitely be appreciated. thanks.
