2004 Dodge Cummins Rotella 5w-40 syn 15,000

All,

This latest sample shows much better Iron, Copper, and Lead. Could the high wear numbers in the previous sample have been caused by a bearing streak?

Thanks,

Wayne

Could you have lugged the engine sometime in the last sample ? Wear is highest with high loads and low revs, even more so with diesels.

Yes, 305/555

Not really as the truck spends most of it's life running down the highway.

Insoluables are running very nice on this analysis. Personally I would stick at the 15K mark because this was a winter run. Even though at 145K miles on an 04 truck it must only be shut off to change oil.

Use a 15W40 dino in the summer and the 5W40 in the winter.

Probably easiest to say, fantastic report.
