Thrown rod!!!

No wasn't out of oil. Had just had oil changed about 1 month prior. Was coming off the interstate and it started knocking. Thank goodness I only live about a mile off interstate so I drove it home. Never lost power or anything. Just the terrible knocking. It has been sitting and hasn't been started since other than when the mechanic looked at it.

Did you ever check the oil after the oil change? Sometimes those places don't get it right!

Actually Scott has a good point.

I had a friend who had his oil changed at a shop and they either forgot to install a new filter, or didn't tighten it down enough, and when his engine siezed he somehow proved that it was due to the shops negligence and they ended up buying his new engine.
