This was run between 2,500 and 22,400 miles in my Forester's 5-speed manual transmission. Viscosity was flagged. This was a Wix prepaid analysis kit. There was a bit of black sludge on the magnetic plug, but nothing that I haven't seen before. I didn't see anything shiny on the plug or in the oil.
I'm concerned about the level of iron, and the viscosity is obviously low. Thoughts?
I refilled it with the same, but maybe I should switch to something else.
