2001 Honda Prelude, 2.2L VTEC, 5L oil capacity, Amsoil SDF-20 oil filter, 70,000KM on engine.
Oil used was Motul 8100 0W-40 Ester, 7000KM on current sample, previous oil was Amsoil 10W-30 ATM.
NOTE: I forgot to take sample while oil was draining into the pan, so I had to take sample from drain pan. Drain pan was relatively clean though.

This is disappointing. Oil has sheared down 2cSt in 7,000KM. Iron is pretty high as well, compared to last winter's Amsoil 0W-30 which yielded 9ppm of iron after 9,000KM. I'll try this oil for a further 10,000KM and test again, hopefully it'll be better. This oil costs $11/L as well, almost as much as Amsoil 0W-30.
