Just a couple of additional data points (conflicting with the above) on M1 0W40.
Vehicle is an '06 Dodge Sprinter with the OM 647 turbo diesel and I have only used M1 0W40 - except for one OC (the 2nd or 3rd mebbe ?) where I used M1 TDT 5W40.
1st oil analysis done with 117,579 on the clock, and 14,183 on the oil: AL showed 7
2nd oil analysis done with 133,541 on the clock, and 15,962 on the oil: AL showed 6
The above analyses were done by Blackstone (they listed the Universal Average for AL at 17) and included the following commentaries by them:
"Your Sprinter looks good, and we don't know if it could look much better than this, but heck it's worth a try." (in reference to my comment that I planned to install a bypass filter) "Metals are low, even though you're running longer oil changes (14,183 miles) than average (9900 miles)."
"This oil was in use longer than your first sample by almost 2,000 miles. ..... Wear metals read at or below universal averages, which are based on a 10,000-mile oil change interval. That means your Sprinter's diesel is wearing better than most of the ones we've tested."
On the second oil analysis, I added a Motor Guard bypass filter at approximately 2K prior to sampling the oil (at a little under 14K miles into the OC)
All oil changes (up to the point of the last one I did @ 135K) were extended beyond the normal 10K recommendation and were changed according to the Sprinter's ASSYST maintenance computer's oil quality monitoring. These OCI's generally ranged from 12K to 14K miles.
My current oil change (M1 0W40) has about 19K on it and I am awaiting the results back from Blackstone from a sample that pulled at around 15K miles into the OC. I will probably sample again at 25K or 30K into the OC if the UOA comes back looking good.
