Rather odd for Chrysler to recommend a 5W-40, but OK.
Mobil 1 makes a 0W-40 AFE that should work fine as 0W-40 and 5W-40 are both 40W at operating temperatures. Mobil 1 5W-40 oils are formulated for diesels, but I would consult Chrysler if using an oil formulated for a diesel is satisfactory.
Most 5W-40 oils are formulated for diesels.
If you want to use Pennzoil, you'll need to use Pennzoil Ultra 5W-40 Euro.
I would call Chrysler and ask them if you can use 5W-30 or 5W-20.
