I guess it has DPF and SCR system right?
In that case go with oils that have lowest possible SAPS content.
My preference is Mobil1 5W30 ESP. You can also go with Pennzoil Platinum Euro L 5W30 or any other oil that meets ACEA C3 requirements, as well as BMW LL-04, MB 229.51, VW 504.00/507.00.
EDIT: I just checked, and Colorado has all emission systems that any BMW, MB, Audi and new VW's have.
So stick to Low-SAPS oils if you want DPF to last long time and if you want to prevent carbon build up. Go with oil that has VW 504.00/507.00 spec. since that is most stringent spec. when it comes to SAPS level.
Like I said, my choice would be Mobil1 5W30 ESP.
