Previous fill was from the dealer. I assume it's Motorcraft 5w30, but I don't think NA is a additive in Motorcraft oil so it might have been Valvoline. It had a Motorcraft filter on it and it was purchased at a Ford Dealer. I went back with the same oil and Motorcraft filter. Car has a MRBP cat back and a Ford Racing cold air snorkel with a K&N air filter. There were quiet a few hard runs car see's max boost and redline on a regular basis, if not daily.

Titanium is an additive in this type of Castrol, but sodium isn't, so the 46 ppm we found here could be a sign of coolant. Usually, though, if that was the case, we'd see high potassium as well, so for now, we think sodium is just residual additive from a previous oil. Wear metals look great (averages are based on ~5,800 miles of oil use, and your wear is low after a longer oil run), and the TBN and TAN are both good, at
6.3 and 3.7 respectively. The slightly low viscosity isn't a concern. We wouldn't jump all the way to 10,000 miles next oil, but try 8,000 and check back.
