If the two were on the shelf next to each other and the same price, I would use the Pennzoil.

What's wrong with the Castrol OE Professional 5W-40? the one my dealership uses meets LL01, A40, 502/505, and I think even the Mercedes spec as well. It also has fluorescent dye added.
Does not meet MB 229.5. It has higher NOACK then M1 0W40, Catsrol 0W40, Pennzoil 5W40 etc.
As for dye: why is that relevant?
Because many many many German cars have the potential to become leaky mofos at random, and the dye helps to track down whether it is a valve cover, VANOS line, oil filter housing gasket, or God knows what else.
In any case, I use Castrol 0W-40. Just wanted to hear your thoughts.
