Please never put 15 quarts of oil in a 6.0, you can cause yourself problems with foaming.
Also, check out oilguard at the top of this page, especially if you are determined to run 15 in the system
13.5 is a great number.

The main benefit is a little better mileage and a MUCH quieter engine. It costs $85.00/case of 4 1 gallon plastic bottles. The engine will only hold 14 quarts.

There are also good discussions and lots of information about synthetic oils in the Misc. section under Oil and Lubricants forum. It's always nice to discuss it here also when specifically pertaining to the 6.0 PSD.
