Re: Is my engine ruined?
LOL, you gotta love shops that can't keep track of their own work. It would probably take only 5-10 seconds of running it with no oil to completely destroy the crank and rod bearings. Since you've been driving it ever since, your tech is obviously not the brightest bulb out there!
As a precaution, it never hurts to check your oil every once in a while. Doing so will give you peace of mind and will guarantee you're never stuck with a seized engine caused by oil starvation.
