Not what I had hoped for. This is my first UOA on this vehicle, and first with Polaris / Oil analyzers / Amsoil. Was bracing myself on iron, copper, fuel, and visc, based on other EB's, but the lead was a shocker. This was Plat pure plus 5w30, and judging from the Ca & Mg, it was D1G2...at least the 5 qt jug. Maybe the extra qt was older, or maybe there was residual oil from previous fill ( 5 qt PPUP, and 1 qt PPPP ). Any chance the lead is just a harmless anomaly? If main bearings, wouldn't there be other metals? Timing chain?
What would you do? Chill or panic?
Driving style: this is my long distance travel camper. So it gets long blasts of highway driving, with short drives while at destinations, often on dirt forest roads. I don't flog it, and don't tow, it's not overweight. This fill involved Oregon to Texas, with a number of stops along the way, then sitting for few weeks, then TX to UT/AZ, then the long drive back to TX, then sitting for a few weeks. Sample was from drain plug, mid drain. Warmed van up with easy 8 mi city street drive before drain.
35k on van, 6.1k on the fill...all changes have been in the 6k to 7k range. Initially using Motorcraft 5w30 blend (except dealer changes were ALWAYS suspect, seriously; one reason I changed to quickielube places, with oil & filter I brought), then the PPUP at ~23k fill, then this PPPP at ~29k. Van sat a lot for several months before first Pennzoil fill. No additives ever (that I know of). Motorcraft 500 filter in all cases.
