I had a complete oil change flush on February 20th. On March 22nd, a loud noise came from my engine. I brought it in, and they said the engine was shot. There was no oil. Everything was completely dry, with no sign of an oil leak. No sensor lights came on. Nothing. I went back to Mr. Lube, and they say they have a video showing oil being put in. Plus, they say I could not have driven very long if they had not put oil in the vehicle. Why did this happen? My car is totaled.

Answer

There was most likely a small internal oil leak.
