I recently ran my 1985 300D VERY low on oil. To make a long story short, I went about 1-1/2 days with a hole in my oil pan. By the time I figured it out, there was almost no oil left in the oil pan. I did not notice what my oil pressure was before I shut it down.

I replaced the oil pan and the car seems to run the same as before, but my turbo might be leaking oil. I'm thinking it might have gotten pretty hot towards the end there.
