    This is a great UOA of the Rotella T syn. Will think about trying this with my solid roller without a doubt. Even with the quart added for 11.5k the TBN of 7.6 is basically where a lot of new 10-30 oils are new out of the bottle. TBN is a measurement of active ingredients. Oil can be run to 1-2 so this oil has a ton of miles left on it.

    To me puts many of the uber expensive race oils to shame. Destroys Valvoline "Racing" oil.

    This isn't my test but a cut and paste from Bob is the oil guy site. Just thougt it was interesting and caught my eye.

    Here is my Used oil Analysis 11,500 miles on Rotella T syn 5-40 62K on the truck with the FS2500 bypass filter. The other UOAs in the pic where using Delo 400 15-40 not much of a change going to run RTS until 14K and do another UOA. I'm happy to see the Silicon down some I'm sure having 62K on the air filter makes it filter a little better. This is a mix of CI-4 and CJ-4 RTS.

    Shell Rotella T 5W/40 (Syn) 1qt make up oil 11,500 Miles on the oil FS 2500 filter

    Congratulations! Your 2006 GMC has scored its first "hat-trick" of perfect reports. This was your second longest oil run since testing began and all of the wear metals in this blend of two different 5W/40 oils matched up well to averages for the 6.6L Duramax. Iron at 20 ppm is due to the longer oil run since iron will track with miles of oil use. Now that your diesel is well beyond the break-in stage you should be able to extend oil use up to ~14,000 miles. The TBN was strong at 7.6 so this type oil had plenty of life left in it. Try 13,000-14,000 miles next time.

    How many quarts does the Duramax hold?

    about 10 on my 2002. I buy 3 gallons, drain it, prime my new filter and douche that gallon down to the 2 quart mark through the open drain because there is a big hump in the middle of the pan and my oil stays cleaner if I wash that out with new oil, then plug the pan and pour the rest of my 3 gallons in. Usually gets it a skosh overfull and I'll try 9 for filling next time if I remember and save a quart.

    All the ones I ever serviced held 10 quarts (INCLUDING FILTER).....measured by a dispensing gun (carried diesel oil in bulk)....not from pouring it out of jugs or bottles. I'd say it's a pretty precise measure.

    I was running Rotella in the camaro during break-in, I might go back to Rotella for the camaro.

    But I'll stick with Castrol in my Ranger.
