especially when ya run synthetic Rotella that costs about 20 bucks a gallon...
BUT, if we had the bigger capacity, the oil would last longer, which would pay itself off eventually maybe right?
Get a FS2500. Ive got 5000 on this oil change and the oil is still nice and honey brown. The filter will also allow to run about 1.5-2 quarts more. With this system, you should be able to go 15k on a oil change. I plan on going to syn rotella t on my next change. With these extended drain intervals, you will make up the diff so you can afford to run syn oil.

I would not run more than the recommended 11 quart total on a factory stock truck that has the stock pan and filter system, more is not always better... Too much oil can bathe the crank too deeply and this condition can and does cause a lot of aeration in the oil and is very bad for bearings... This goes for all engines, be it Diesel or gas... I have spoken with a very reknown crank/rod/piston/cam/rocker maker and a Mobil 1 consultant and they spoke in no uncertain terms about their feelings on this... Cummins and petroleum engineers aren't substandard, and if they thought 12 or more quarts would've been better then You can rest assured they would have required so... They want their engine to last as long as possible... I'm not trying to be a big shot, but I have seen few engines that has scorched bearings due to this very topic... I'm passionate about engine longevity, mine and others...
