I have a friend that also drives a Ram 1500 3.0L V6 EcoDiesel. At my suggestion last year........ He got to the point where he wasn't worried about warranty and wanted to test his oil to see how long it should really last (He recently switched from EuroL 5w30 to Rotella T6 5w40). He has tested two samples, both right at 10,000 miles on the oil.
In both cases, the OLM on his truck reported that the oil was at 0% and needed replacement at 8,200 miles on the first one and 8,700 miles on the second one.
Oddly though, Blackstone suggested he move his Oil Change Interval to 11,500 miles based on both samples.
So what are we to believe and how accurate, really, are the OLM's in our vehicle software????
During the spring, summer and fall.... he was pulling his boat trailer a lot. He mentioned to me that when he is not towing with the truck, the OLM usually hits 0% around 9,500 miles. So is the OLM nothing more than a logarithm based on..... maybe a collection of RPM data rather than the true scientific condition of the oil? Ie. Higher RPM's when towing = less miles according to the OLM.
