Sixto:
It is nice to have it for a Diesel engine, that much less exposure to the "liquid tar" that oozes out of the crankcase. You're looking at roughly 7 or 8 quarts being removed, so make sure you have enough capacity, the 103 of course is closer to 6 1/2 quarts.
For your own piece of mind, I would recommend the first time you change oil in this manner to pull the drain plug and make sure your equipment is doing a good job of getting all the oil out. As with any oil change, make sure the engine is up to operating temp before extracting.
