Just keep in mind that not all 5W40 oils are OK. Mobil 1 has a Euro 5W40 oil on the shelf at Walmart, but if you dig into the specs on their website it specifically says "not for vehicles with DPF". You need to be careful what you buy for the EcoDiesel.
I'm running and testing the Quaker State oil still, but my next experience will be with the Motul X-Clean. It's listed at <0.8% SAPS which is as low as you'll find on an approved MS-12991 oil.
Do you happen to have the SAPS specs on Quaker State or Pennzoil Euro? I've been running Pennzoil and moving to Quaker state soon.
On a side note, I'm at 30k now and waiting for 3rd oil analysis to come back but the last 2 had high aluminum content, 22 and 21. If it continues to be high I'm not sure what to do.....wait till something fails? Oil still has plenty of life left per the analysis so I don't want to spend even more $$ changing it every 5k or less. Now I'm changing every 7500. Truck is always at 25% oil life when I change.
