That iron still hanging in a touch higher than before but nothing I'm worrying about. Who knows. Climbed a little bit after the new turbo and hasn't settled down like before. Sill seeing low SiO2 with that open intake/K&N. Went back to Liquimoly Molygen this time after trying 3 of the popular Wallyworld oils the last 3 changes - M1 0W40, QSUD 5W40, and this M1 5W40 (in order). Viscosity drop is in-line with what it always is. No consumption at all this go around like normal. Driving the same - aggressive with lots of high RPM/elevated oil temps (no track use). Fuel is 93 and typically I run 2-3 gallons of ethanol for a roughly E22-ish blend.
