Mobil 1 ESP 5W30 = FAIL
Almost double the iron content. Operational difference between the two runs: April sample was from winter run of mostly short trips. August sample was from Spring/summer run of almost all highway miles. Operator's employment changed from local in town job to out of town requiring 50 mile commute each way each day, hence the highway miles. Nothing else whatsoever changed. Note TBN exhausted in 2nd sample for same length of run as compared to previous. M1 ESP 5W30 is VW spec 507 approved, and VW approves 507 spec oil for use in 2004 - 2006 USA based TDI's, as 507 supercedes 505.01 and 506.01. In the previous report, Blackstone stated the Mobil 1 ESP was working well and to consider extending OC to 11,000. So much for that.
I will be switching the car back to Mobil 1 Turbo-Diesel Truck 5W40 CJ4 as soon as possible.
