So the dealer put 5w-20 rather than the specified 5w-30 (which I knew from the invoice) but it still did OK. I did a lot of towing with this in summer traffic so I am impressed. I now have Edge 0w40 in there which has been proven in DI turbos and did well in my 335 so I expect the next UOA to be a good one.

Comment: Metals and silicon have improved by leaps and bounds in this second sample from your

Expedition's V-6. Aluminum and copper are now within a normal range for wear, although we wouldn't be

surprised if they decreased even more next time. Silicon's still a bit high, but that element tends to take a

while to wash out (and it stated at a whopping 261 ppm!). No excess fuel dilution or other harmful

contamination turned up and the TBN was still strong at 3.6. This was Motorcraft's 5W/20 oil (note the

barium marker) and it did a good job for you. Nice report.

Looks like everything is trending in the right direction, I'd be happy with the result. Looks like the factory fill was a 20Wt oil also? It was only 7.14 cSt @ 212, seem pretty thin. It did have a lot of fuel in it however. Flashpoint definitely improved, but still probably has some fuel in the oil as the flashpoint should be 402 (fresh oil MC 5W20). Curious to see how the Edge does, good luck!
