While there is nothing wrong with your logic (Rotella Syn every 5k is fine), the cost isn't quite half... $16 vs. $22 means the Rotella about 30% less. The M-1 TDT comes in a gallon jug, though... can't remember offhand if the Rotella Syn is a 4 or 5 quart container. If it's 5qts for $16, that would make the difference $3.20/qt vs. $5.50/qt, for a 40% savings...
But you're also changing the oil twice as often. Personally I'd rather spend less time under the car! And, even with the cost differential... at $3.20/qt every 5k, vs. $5.50/qt every 10k, it's actually cheaper to use the Mobil-1 (Rotella would be $6.40/qt every 10kmi, M-1 still $5.50/qt at 10k).
