Gang,
Here is UOA #3 on the Explorer, this time with Kendall GT-1 0W-20. The same combination went back in, but I will be switching to M1 after this run. Though I had hoped to see the silicon continue to drop, it actually rose this time so I will be checking the air filter and associated connections to be certain that I do not have a leak.
Else, all looks pretty good. Enjoy!

3rd UOA Comments: We were wondering if some fuel would turn from starting the engine to put the truck on the ramps,
but nothing was present here. Some engines are okay with a brief start-up prior to sampling, and some
engines can leave a little fuel in the oil in that scenario. A little fuel in this oil wouldn't have hurt anything
anyway though. Copper continued to improve nicely, even with the longer oil run, so we're seeing some
good progress here. Silicon increased, so you might give your air filter/intake a quick once-over to look for
issues. The TBN was fine at 2.5 since 1.0 is low.
2nd UOA Comments: Here's the lower wear we mentioned. You even went twice as long as last time and still got
improvements. The wear-in stuff is washing out nicely. Copper is still pretty high, but that metal tends to take
a while to wash out and there was more of it to start with. Silicon can take a while to wash out too, but the
improvement is still a good sign that the air filter is getting the job done. You'll notice titanium and sodium
here, but they're just additives in the oil itself and not harmful. The viscosity is correct for a 5W/20 with no
fuel or coolant was found. Doing okay.
1st UOA Comments: There's nothing unusual in this factory sample from your new Explorer. High metals and silicon are
common in factory oils. The metal is from new parts wearing in and silicon shows harmless factor sealers.
We looked ahead and things look a lot better in the next sample. It may take a couple of oil changes, but
this engine should look like universal averages soon. They show typical wear levels for this type of engine
after about 6,000 miles on the oil. No fuel or coolant showed up and the oil filter kept insolubles low.
