I also discovered a gallon of rotella 10-30 on the shelf mixed with my supply of 15-40 when I did the oil change. I had forgotten that I bought a case of 10-30 last December when I thought I was headed to Niagra Falls for Christmas.
The rest of the case was missing so there is the distinct possibility that the first time I made this trip with the car I had accidentally put 10-30 weight oil in it. That might explain the excessive oil consumption as well.

I did the same thing with my ‘73 240D partly because I was ignorant and partly because there was a case of 10w-30 i the trunk whenI bought it. There was more oil on the engine than in it. I just assumed a quart a day was the cost of owning an old diesel. Fortunately at the time you could always find a case of 10w-30 on sale for $5 and diesel was always cheaper than gasoline.
