Ok, last night I was driving along... Suddenly the oil warning came on. The red one. It also said stop engine check oil level. I pulled over and checked the oil.. It wasn't below the line. The level seemed to be ok, but I added a bit of oil in case. I just had the oil changed 2 days prior. I started driving home and the car started running like crap. Occasionally, there was a squeaking noise. The car had no power and I couldn't hear the turbo. There were no CEL, just the oil light which never went off.

Any suggestions?
