UOA by Oil Analyzers Inc.
Driving conditions: Oil in use since March 2011; 7 mile daily commute each way; spirited driving with a few redlines here and there on days where I have a 30 minute drive. A trip to SC during June. Most of my consumption is usually on trips if I’m driving on the interstate at steady highway speeds. 3500 rpm's at 80 mph. Cobb Stage I "Off The Shelf" ECU reflash done 700 miles ago. +29% HP/+21% Torque. Probably not done early enough to affect this OCI though.
Comments: Lubricant and filter change is suggested if not done at sampling time; Infared results indicate OXIDATION is SEVERELY HIGH. Infared results indicate that NITRATION is at a SIGNIFICANT LEVEL; FLAGGED ADDITIVE levels indicate slight LUBE MIXING

I'm thinking that most of the oxidation is from the ester based Motul. I'm happy with the low wear. TDS states the viscosity on this oil is 11.9 and TBN is 11.2.
Haven't changed the oil yet.
