My oil report came in after my first oil change and I think I should have ran the oil a little longer. Seems like the dealer had done an oil change prior to me buying the car. Not much information from this one I suppose? Looking forward to the next one after 6500miles on 0w40.

Without TBN and TAN it's hard to say how much longer it could've gone. Viscosity is still within spec and none of the elemental metals looks high.

While not everyone agrees with switching oils, with that kind of lead ppm, I'd switch to lighter oil. Just my 2 cents.

Thanks for looking, I will pay for TBN and TAN next time - I didn't because I suspected the oil hadn't been in there that long judging by the color and what the sales guy had told me.

Color means nothing, unless you are looking for coolant contamination. Oils turn black under use.

Ahh, good call. So what do you look for on a 2011+ to determine bearing wear?

Guys, for the umpteenth time, you cannot use a UOA as the only gauge for bearing wear. Even Blackstone says it is not an authoritative way to check engine health. There will be engines that run for 200,000 miles with high particulate counts, and some that need rebuilds in 20,000 with "perfect" reports.

One of the major reason I switched was after I installed an oil pressure gauge, I have noticed that on cold starts where I left the car outside over night, the oil pressure is way high in the 95-100 range. It's almost like the oil is not flowing at all for a minute or 2. If you leave a bottle of 10-60 outside over night in the winter, you will know what I mean. I figured as I don't drive hard at all, it wouldn't hurt to give it a test during the cold time just to see. Oil pressure never went pass 90 during cold starts with the 0w-40. Another plus I think with 0w-40. Will see what BS looks like during the next oil change. Leaning towards using 0w-40 year round but undecided on what to use during the summer months yet. For sure will use it during winter season.

It looks like blackstone doesn't create their averages for the years where lead/copper were removed, no?

Their averages are generally for a given engine. They don't differentiate between the years.

Yeah, it appears that way indeed; probably not common for auto manufacturers to change the internals like this so it may be difficult to differentiate the years.

Lead was high. Change interval was about 14k. I used 0w40 to try and get my lead down this time.
