I took my first sample on my '03 6.0 PSD at 24,000 miles. I bought it new and have till 6-18-2010 Ford warranty left. I have been running Rotella 5-40W Synthetic 2,600 mile on sample before I was to try the Rev-X. After adding the Rev-X I noticed that the turbo was Spooling up quicker and getting higher PSI. So far from another forum many have said it could be the turbo.

The high copper and lead readings would initially suggest a serious problem developing in the bearings, but these levels of metal also tend to turn up when Restore additive has been used. If that is not the case here then this 6.0L may need some attention. All other wear metals read right around universal averages, which are based on an oil run of about 5,200 miles. The oil's viscosity was quite low for 5W/40, reading more in the 10W/30 range. No fuel was present, and the TBN read strong at 7.3, showing lots of active additive left. Let us know on the Restore.
No Restore has been added.
